    “1.Human Population Growth-Cole Kinchler”

    This article on Human Population Growth is entitled “7 Billion” this is because in 2011 there is estimated to be 7 billion humans on Earth. In the article it discusses the increases of growth that the world has had, for instance in 1930 there were 2 billion people and this number has continued to double every couple of decades until now. Some people can say that they have lived to see the population double or even triple in their lifetime. The article say that an estimated 10.5 billion people will be alive by 2050, if the rapid growth of our human population continues to grow the way it had. The article says that generally after war times there is a baby boom after soldiers return home, which sometimes produces an unusual jump in the population size. Another factor to the human population growth would be that women are having less babies which has in a way slowed down the rapid growth that the world was having, but since there are so many more people now than there were a while ago the population still rapidy increases if each women just had 1 baby.

    In this article I learned a lot of new information about the population growth that I had no clue about before. For instance I knew that a lot of people were on our planet, but I did not no that it was so close to 7 billion. In the article I learned that in other countries that do not have different medicines or decent amounts of food that it signifigantly decreased their life expectancy, and when some developing countries recieved some medicines or extra food their life expectancy increased and they slowly over time began to have less babies because of this. The article shows that in more developed countries people are less likely to have more offspring while in nondeveloped countries they generally have more. I had already known about the reproductive patterns of developed and nondeveloped countrues, so when I read that part of the article I recognized that information to be true, and it helped me learn more about the rest of the information in the article because i felt a connection with that part.

    Antoni van Leeuwenhoek was examining a small specimen under his microscope that he himself had made. He noticed animalcules swimming around and became very intrigued, some would say obsessed. He saw all of the little specimens swimming around and then translated that information to how many people inhabited the Earth. Leeuwenhoek estimated there to be about a million people in Holland, then using maps and geography he predicted that the Earth’s capacity was 13.385 billion people. A century and a half later another scientist discovery human egg cells, causing the world’s population to double to more than a billion. A century later it doubled again to two billion. Before the twentieth century no one had lived long enough to see the population double, but in today’s society we have seen it triple. In 2011 there was an estimation made of seven billion people on Earth. The population has increased and it is said that by 2050 the population will reach 10.5 billion, or it could stop at eight billion. The tally depends on the choices individual couples make when it comes to having children. The population still grows about eighty million each year. Earth’s water tables are falling, soil is eroding, glaciers are melting, and fish stocks are vanishing. Close to a billion people go hungry each day. In the future there will likely be two billion more mouths to feed. That doesn’t even include those in poverty trying to find a way out of poverty.

    Population has worried many people for a long time. In 1798 Thomas Malthus presented his general law for population which says that population will grow until war, disease, and famine reduces the number of people. That same year a smallpox vaccination was invented and nearly doubled the average life expectancy. Ehrlich said that millions of people would be saved from illness with proper medical care, and the green revolution began. After World War II, penicillin, the smallpox vaccine, and DDT were sent to other countries to help with medical care. The life expectancy doubled in many countries, causing a world wide population increase. With the assistance of vaccines, women didn’t have as many children because now the majority of children made it to adulthood. This is what some people call a hallmark of human progress, and all countries go through it.

    This article talks about the many different things that effect our population in the every day world, such as starvation, death, disease, war, and the choice to have many kids or few kids. This article taught me many new things, for instance I learned that Leeuwenhoek made his own estimation, and even without a census to go off of. I knew how the amount of food affected a population, but it shocked me as to how just giving a country a little more food can really help them boost their population. It never occurred to me, until now, how much we rely on medicine and how much it affects us. Without medicine our life expectancy would dramatically drop and women would have more kids to increase the chance of them having their own children.

    1. human population growth- Tyler Aderholt

    Antoni van Leeuwenhoek was a cloth merchant whose hobby was microscopy. While examining objects he discovered animalcules. This inspire him to figure out the Earth’s population. With spherical geometry and a map he estimated that about 1 million people lived in Holland. After this he concluded that there couldn’t be more than 13,385 billion people on the Earth. Historians later stated that there would have been around half a billion people on the earth at the time of Leeuwenhoek. A century and a half later the population had doubled when a scientist discovered human egg cells. In 1930 the population doubled again to 2 billion. In late 2011 the UN stated that the population was around 7 billion. With more women now in their child bearing years, the population will continue to grow. By 2050 the population is estimated to be around 9 billion people. With the population growing at about 80 million people a year the Earth’s resources are starting to run out or deplete. Close to a billion people go hungry every day and with new medicines and inventions to keep us alive longer that number will continue to grow.

    This article was very informing. I had no idea how quickly and drastically our population has grown over numerous centuries. I did have an idea that there were about 7 billion people on the Earth today but had no idea that our population increases 80 million people a year. My point of view is that it will continue to grow because we are always coming out with new medicines to cure sicknesses and diseases. We create new machines to make our jobs and lives easier which will cut out injuries and deaths. We also need to start becoming aware of our natural resources and start doing something about it so we have resources left in the near future.

    “1. Human Population Growth – Anna Davis”

    The frightening idea of the apocalypse has haunted the minds of humans since the first man had the audacity to fathom the idea of an “end” of time. There are many theories behind how it will happen, when, and its causes, but one that many seem to agree upon is the idea that the earth’s population will grow too large to support itself. In this article, this belief is addressed, and somewhat supported, due to the fact that the human population is suspected to grow from its current 7 billion, to an astounding 10.5 billion in 2050. This percentage of growth is almost unfathomable considering that in the late twentieth century no one lived to see the population double, unlike today when people can see it triple in a lifetime. The worry with the population growing at such an exponential rate is that the Earth is not going to have enough resources to support such a large population. Already today, over 1 billion people starve daily, and that brings fear for the future where the population will have only grown. The problem for a time was that too many children were being born, while new rises in healthcare extended the lives of the ones having them. Because of this, the number of people living at a specific time rose, rather than the births equaling the deaths, so that the population stayed at a constant, a concept known as “replacement fertility.” Today, many countries are reaching replacement fertility, or even falling below it, as women are educated and preventive options are being given so that less children are being born. This is a step in the right direction, though in countries like India, the fertility rate is still so high that other more radical options are needed.

    I learned a great deal from this article, and in a way, I feel as if my eyes have been opened. I regrettably admit that I’ve never put a great deal of thought into the problems of the growing population, mainly because I live in a country where most families have two kids for whom they can provide. It never really struck me that in some places, overpopulation is a great problem. Such a problem, in fact, that in places like Rwanda, it could be a factor in mass genocide, like the article stated. The article also made me more grateful for my own upbringing and culture, where even as a woman, I have the opportunities to become educated, decide how many children, if any, I would like to have , and know that my standing in society can be whatever I’m willing to work towards. I have deep sympathy to the women in India I read about in the article, who’s only chance to rise in mainstream society was through having children with the right men and then securing their places with male heirs. It saddened me that over fifty percent of them are illiterate and marry before the age of 18, giving them little other options than having many children because they have never been given the opportunity to know that there are other options available to them. I think, after reading this article, the best way to reduce the population growth, is to educate these women and give them the opportunities they lack so that they, too, can realize that their self-worth is not measured only in how many male heirs they can produce.

  • 5 1. Human Population Growth-Daniel Gilliland // Jun 3, 2011 at 9:51 am

    According to this article, and the United Nations, the population of the world will be at 10.1 billion by the year 2100. This could easily be gathered by looking at the title, “U.N. Forecasts 10.1 Billion People by Century’s End.” A lot of this has to do with Africa, whose population is rapidly growing. This is slightly bad news considering it is already difficult for the ones there to get food and water. Another factor is that fertility rates are not declining as expected in some poorer countries, and they are actually increasing in wealthier ones. According to Hania Zlotnik, the director of the U.N. population division, some countries now face the choice of whether to renew family planning programs. Such programs have actually stalled in many countries. In this forecast though is the assumption that food and water will be able to be provided to the billions yet unborn, and that things such as climate and wars will not be a factor to limit growth. If needed, it is possible to bring down growth rates in poorer countries with well-designed programs. Women in places like Bangladesh and Iran have chosen to have fewer children with voluntary access to birth control. Also, the AIDS epidemic has not done all it was expected to numberswise, which is a good thing. More factors in Africa include lack of women power in relationships, early marriage and polygamy. Also, a much smaller percentage of women in Africa use contraceptives than elsewhere in the world. Some studies show that providing them may not be sufficient. It may take women feeling more independent before they choose to have a smaller family size. Meanwhile, China’s population is projected to actually decline, and the U.S. is expected to continue to increase due to immigration and higher fertility.

    I thought this article was very informative, and I learned a lot from it. I didn’t know that the population of the world was growing that rapidly at all. It certainly makes me wonder what we would do if the population of some places in Africa got as high as is expected. It would likely grow very hard to sustain all these people in the world. As for the United States, our population has not stopped growing, and that can only mean less space for those of us in the future. One has to think how many more places will be cut down to put up more housing for people moving in. The article mentioned Yemen, whose population has quintupled since 1950 to 25 million. Yemen already has critical water shortages, so if it and countries in its area continue at this rate, could that possibly affect us over here? I’m sure it would.

  • 6 1. Human Population Growth-Leah Reeve // Jun 3, 2011 at 4:10 pm

    The title of the article I read is “Africa Needs Population Growth, Not Birth Control”. The United Nations released population expectations stating that Nigeria will reach 725 million people by 2100. This projection scares the West and they are calling for Nigeria to limit their growth. The author of the article, Chinwuba Iyizoba, talks about the African view of population growth. He says to rejoice in population growth, not try to control it. He claims that the theory that high population growth will soon deplete the food resources and send the country into poverty is not true. The real cause for poverty in African countries is corrupt leaders and that western governments turn and look in the other direction. The population growth in Nigeria is a good thing because 1) it gives financial security to large families that take care of each other since there is not much social security today and a bigger family means a better pension, 2) they avoid the huge pension debts that are upon the populations in America and Europe, and 3) a large population means a large workforce to help the markets grow and prosper.
    I found this article very interesting because everything I have heard my whole life about human population growth being bad is refuted in this article. The author says he is one of seven children born in Nigeria. I would think that since Nigeria is a poor country it would be hard to sustain a family that large, but it is the culture in that country and how they survive. By limiting their population who knows what would happen. Birth rates would go down but as the author pointed out in the article, American birth rates are going down and whites may soon be a minority in the U.S. I thought this was a very good article that helps you see and start to understand the situation of population growth in other countries, not just America.

  • 7 1. Human Population Growth - Erin Markus // Jun 6, 2011 at 3:48 pm

    The article “Population 7 Billion” points out that from as early as the sixteen hundreds there has been talk of how many people the world can hold. A man by the name of Antoni van Leeuwenhoek was able to use his knowledge of the population of Holland and spherical geometry to predict that Earth could not possibly hold more than 13.385 billion people. This number, at that time, seemed unreachable. However, by 1930 the world population had already reached two billion. It is expected that by the end of this year, there will be nearly 7 billion people living on Earth. This number has increased so heavily due to a couple of major factors. One of the major contributors to the increase is due to advances in medicine. People are now expected to live almost twice as long as they were in the seventeen hundreds. With new advances such as vaccines and antibiotics, along with better nutrition and sanitation, the average human is expected to live to 77 years old. Another reason for the population growth is that nearly 1.8 billion women are currently in their prime childbearing years. The fertility decline is currently influencing millions of women to only have two children to replace them and their partner. The article points out that if each of these women produces two children, by 2050, the population could reach nearly 10.5 billion people.

    The article, by Robert Kunzig, did a great job describing the population increase overtime and its effects. By following population increase from as early as 1677, Kunzig provided the reader with a history that for most readers would otherwise be unknown. It also presented the reader with many shocking numbers to demonstrate future predictions of the population. Another interesting part of the article were the cause-effect relationship reasons for the population increase. One of the more interesting ones that he pointed out, was how the discovery of chemical fertilizers led to an increase in crops such as corn and potatoes, which ultimately led to the end of starvation in certain parts of the world. Overall this article was a very easy read and at the same time very informative.

    The world’s population is said to rapidly increase within this century in the article “U.N. Forecasts 10.1 Billion People by Century’s End” by Justin Gillis and Celia Dugger. This article establishes that this drastic increase in population might not be the best thing for some countries. The article starts out by stating that Africa’s population of one billion will triple to 3.6 billion within this century alone. However, the tone of this fact is somber, mentioning Africa’s need for food and water, even at its population now. As population grows, so does the need for basic essentials needed to survive, which causes a problem. Later, Gillis and Celia quote John Bongaarts when he says that the world would be better off with a smaller population. There is also an emphasis on family planning within countries. This article states “Well-designed programs can bring down growth rates even in the poorest countries.” These “programs” mentioned are like information and access to birth-control, abortions, family planning programs, etc. It is concluded by stating that the population of U.S. is quickly growing and is projected to rise from 311 million to 478 million by 2100.

    This article helped in my understanding about the world and its growing population. Statistics in here shocked me. I have never taken the time to think about how much population affects…well, everything: the economy, food and water sources, and demands, just to name a few. I was also a little saddened when it talked about Africa and its food and water crisis. I knew that Africa had this problem; however, I never took into consideration the fact that an increasing number of babies are being born each year and will also need food and water. Another point that caught my attention was how many countries are trying different ways to prevent this dramatic increase of people with birth-control and abortion and family planning. In China, they even have a law on how many kids you can have, which I never knew. With all of the facts and predictions, I can say that I now have a new view on the world and its changing population.

  • 9 1. Human Population Growth - Emily Beckett // Jun 10, 2011 at 10:13 am

    The human population has grown tremendously over the last few centuries. The world population grew greater then 6 billion just before the end of the 20th century. Population estimators predict the world population will reach 8-12 billion before the end of the 21st century. Although this population is very high almost half live in poverty while the rest live a comfortable and healthy life. The rapid growth of the human population sometimes can hurt the financial and natural resources needed for families. The article “Population Action” said that the number of chronically hungry people increased by 4 million per year in the mid-to late 1990s. The article then tells that in Ethiopia 12 million of the 77 million people are threatened from famine and food insecurity.

    Fertility plays a huge role in the human population growth. More developed countries have lower fertility rates while the less developed countries are higher. This is controlled by economics. The high fertility of the developing world is expected by the number of jobs, like low- technology agricultural tasks. As technology improves, families start to decrease their production because it decrease their standards of living.I think this article helped my understanding of human population around the world, and how it effects people’s lives.

  • 10 1. Human Population Growth - Sean Kennedy // Jun 10, 2011 at 6:34 pm

    The article that I read was called 7 billion. This refers to the 7 billion people on Earth in 2011. The article mainly covers how the population continues to grow and how it could become a problem in the future. Leeuwenhoek estimated that the Earth could only hold about 13.385 billion people and continue to support them. The UN demographers estimate that in about 2045 the population of the world will reach about 9 billion. This increase in people throughout the world makes it harder to get the resources that everyone needs to survive. Some countries already do not have enough resources. Some countries have noticed this and have made programs to slow the increase in population. One instance is in China. China made a law where a women could only have one child thus reducing the rate of increase in population.

    This article was very informative. I was shocked on how drasticly the population was growing. I believe we need to make sure we have enough resources in the future. However the population growth will continue because of our advances in medicine. After reading this article it has made me more aware of the problems with population growth.

  • 11 1. Human Population Growth - Jordan Wagnon // Jun 18, 2011 at 2:04 pm

    This article was about the drastic changes in human population. Soon, if not already, there will be seven billion people in the world. Not long after that, in 2050, there could be around 10.5 billion people. There are lots of reasons for this- increased life expectancy, fertility, peacetime, sanitation, medicine advances, etc. The question is, how many people can the Earth hold? Antoni van Leeuwenhoek predicted in 1677 that the Earth could only hold a little less than thirteen and a half billion people. And with the continuing increase in population, especially in poor countries, who knows how long it will be before we hit that number? Or pass it? Right now the population is about 60% in Asia. That is going to change though- the African population is expected to almost double in the coming century. While this is a step towards a more evenly spread population, the increase in people will cause major food shortages, among other things.

    When I read this article, I was shocked. I had no idea that population would be such an issue in my lifetime. We need to start working now to find new resources- food and clean drinking water, oil for heat, etc., because, as if the problems now weren’t big enough, they’re about to get bigger.

  • 12 1. Human Population Growth - Gray Johnston // Jun 19, 2011 at 1:58 pm

    The beginning of this article talks of a cloth merchant named Antoni Van Leeuwenhoek who is very fond of microscopy. While looking through his self made microscope Leeuwenhoek noticed animolecules. This discovery intrigued Leeuwenhoek and made him want to expand his research to the world population. He guessed that the world’s resources could only withstand a population of 13.385 billion. The world’s population is rapidly increasing due to the number of child bearing women in the world. The world’s population increases nearly 80 million people a year. At that rate the world is expected to have close to 9 billion people. In some places in the world up to a million people starve each day. Restrictions are already being made in some countries to try and slow down the world population, but at the rate the population is growing the resources in the world will soon be depleted.
    This article was very eye opening. I had no idea our world population was increasing so fast. We do need to make plans to try and save our resources, but trying to control our population is not going to work. With the advances in medicine and better working conditions we have today, people are going to live longer. The world needs to figure a way to live without the use of all of our natural resources. This article has made me aware of the threats our population has on the world.

  • 13 1. Human Population Growth- Madison DeHaven // Jun 19, 2011 at 2:26 pm

    As the years go by, the human population is growing tremendously. Due to this rapid growth, ecosystems are unable to provide to all that live in them, climates are changing for the worse, and many countries are sinking deeper into poverty. It is assumed that if nothing is done to slow this rapid growth of humans, the world population will reach 11 billion by the year 2050. This number is so outrageous that there is no way the earth can support this much life and famines will be guaranteed to break out. Also, the arising children will not all be able to recieve an education due to the fact that there will be so many of them and not enough to teach. The growing number of humans will also require a growing need for energy supplies, which will lead to more and more pollution and global warming. Something must be done to prevent this growth in human population through things like voluntary planning programs and an easy access to contraceptives because if something is not done to slow this growth, it could be the end of us all.

    This is an issue I have also thought a lot about, especially after attending a festival of 400,000 people and not being able to take one step somewhere without bumping shoulders with someone else. It made me think, if this is how bad it is in just one city inside one state, I could not imagine how it is in places like California and New York. Which then got me thinking about how bad it will be years from now. This article not only opened my eyes to the problem of population growth in the U.S., but also the popultion growth that is more rapid around the world like in Uganda, which in 1950 had five million people and today has 25 million and by 2050 should reach 127 million all in just one small part of the world. This article confirmed my thoughts with actual numbers and graphs of how bad it could get if we do not do anything to prevent unnecessary growth of humans.

  • 14 1. Human Population Growth - Stephen Lea // Jun 19, 2011 at 10:09 pm

    One problem that the world faces everyday is how to support an ever increasing population. How do you feed such a large number of people when the population is expected to increase to 10 billion by 2100. Climate change also makes growing the food more challenging for farmers to keep up with demand. Most people in developing countries want smaller families but have a hard time controlling the implementation of family planning. One side thinks that the food production industry needs to work together with those who fight for population control. The other side thinks we just need to use our resources more efficiently.

    This articles goes with many of the things I have heard about population increase. The population has to slow down or the food industry must speed up. I however agree that food resources could be used more efficiently, and that in itself would help greatly.

  • 15 1. Human Population- Ali Goff // Jun 28, 2011 at 2:39 pm

    I also read the article “Population 7 Billion”. It talks about the rising populations and the predictions of those before us. It questions what will happen with the rising population to the Earth as we are already facing problems such as global warming, pollution, starvation and much more. It states that the childbirth per woman has gone down, in a lot of places below replacement rate. Ultimately this article says that we need to stop worrying about the number and start worrying about the conditions faced by the people and how people are consuming resources. In fact, it said that if Texas were to be as densely populated as New York then the whole world population could fit into it.
    I really enjoyed reading this article and I liked how the author didn’t try to tell you what they thought the population was going to be by this date. I really liked that the author made the problem more about the poor conditions the increasing population was facing instead of what the population would increase to. I think this topic is important to everyone, because it affects all of us and our future.

  • 16 1. Human Population Growth- Caitlin Miley // Jul 6, 2011 at 10:37 pm

    http://ngm.nationalgeographic.com/2011/01/seven-billion/kunzig-text

    National Geographic is doing a special series on the topic of human population growth, including many fascinating pictures and articles. I read one of the articles, titled “Population 7 Billion.” It tells us in the article that it has been predicted that by the end of this year the population will reach 7 billion. This has many people concerned that the Earth will not be able to support such a large population size. However, the articles gives some comfort by reminding us that our knowledge of science and medicine have only expanded, and people have been worrying about population size for many, many years now.
    It amazes me how fast population can grow. One way populations can boom is by introducing new medicines. For example, developing countries were introduced to things such as Penicillin after World War 2. Drugs such as this caused the life expectancy in these countries to greatly improve. Because people were living longer, they were able to have more children, which caused an increase in population. The article said that there are people today who have seen the population triple in their life time. It also predicts that I could easily be alive when the population hits an estimated 9 billion by the year 2045.

  • 17 1. Human Population Growth-Maggie Cox // Jul 10, 2011 at 2:06 pm

    While looking through his homemade microscope in 1677, Antoni van Leeuwenhoek decided to calculate Earth’s human population. He finally concluded that there were less than 13.385 billion people in the world. Historians have estimated that there were actually only about half a billion people on Earth during Leeuwenhoek’s time. Since then, the population has only been rising. According to the UN Population Division, it is estimated there will be seven billion humans by later this year, and the global population will continue to grow for at least a few more decades. By 2050, it is possible the population could reach 10.5 billion. The population grows by almost 80 million each year. With the lack of fresh water, eroding soil, and food sources dwindling, around a billion people starve each day. These growing numbers have many people worried. Decades from now, it is possible there will be two billion more mouths to feed, and most of them in poor countries. In 1798, Thomas Malthus stated that the populations grow faster than the food supply until war, disease, and famine cause it to decline. However, historians believe the world population hasn’t fallen since the Black Death of the 14th century. As advances in medical science increase, so does the population. Each day, lives are saved due to medical science. Since the eighteenth century, fertility has been declining. Women don’t have to have as many children to carry on the family as they did in the past. Hania Zlotnik, director of the UN Population Division explains, “We still don’t understand why fertility has gone down so fast in so many societies, so many cultures and religions. It’s just mind-boggling.” Unfortunately, in 2030, the largest generation of adolescents in history will be having children of their own, causing the population to soar for another quarter century. Hopefully by that time people will be able to live humanely and in a way that doesn’t destroy the environment.

    It’s insane to think how many people live on this earth. Before reading this article, I knew it was billions, but I couldn’t have guessed. As the population continues to increase, I worry about what humans will do in the future. So many countries around the world lack clean water and food. The number of hungry people increases each day. What are we to do? I believe if people don’t start respecting the earth and all it’s natural resources, future generations will be in deep trouble.

  • 18 1. Human Population - Amanda Boutwell // Jul 13, 2011 at 11:24 am

    According the the CNN Tech article, world population projected to reach seven billion in the year 2011. In the developed world, the United States and Canada will account for most of the human growth- half from immigration and half from a natural increase in population. High fertility rates and a young population base in the developing world will fuel most of the growth, especially in Africa where a mother will often give bith to six or seven children over a lifetime. There are several problems with the ever growing population. Food, territory, and education could all become scarce. Today we face problems such as global warming, pollution, and starvation so the conditions of a rising population are a worry in our lifetime.

    Personally, I think the Earth and our economy will be able to support the ever growing population. Yes 7 billion is a scary, crazy number to deal with, but what hasn’t our country dealt with? This article did teach me about the struggles we are dealing with as the birth rates increase, but just as babies are born… people also die. It’s the circle of life and it’s a never ending cycle that the Earth will deal with forever.

  • 19 1. Human Growth Population - Anna Catherine Manning // Jul 13, 2011 at 7:16 pm

    This article suggest that the population of our planet is expected to grow to numbers that are completely overwhelming. According to a report released by the United Nations, the population is expected to hit 10.1 billion by the year 2100. Scientist are questioning if the planet can support 10 billion people because an overwhelming population brings complications. Factors contributing to these statistics are that of fertility and how it’s not declining as rapidly as some poor countries expected, ideological battles over abortion, the role of women in society and the variety of new treatments now used to prevent death. The need for materials such as food and water will skyrocket due to it becoming scarce in some areas.
    Most overcrowded countries already depend on America or other countries for their import of resources. Examples are Nigeria and Yemen. These are just examples of fast-growing countries that are in desperate for education and other plans to control the population.
    The United States is also growing at an incredible rate; a rate faster than any other wealthy country. This is mainly due to the high immigration and the higher fertility among Hispanic immigrants. The director of the United Nations is now faced with a choice about whether to revisit ideas and programs that deal with education and family planning. Economist at the Center of Global Development in Washington say there is a need for family planning services in all countries but especially in countries where there is a high population of AIDS. Well designed programs with information and voluntary birth control methods can bring down the growth population.

    I tend to agree with having programs to educate family planning but especially in countries where there is limited supply of food and water resources. It already seems out of control in some countries. You cannot hardly watch tv with seeing and hearing about the over populated areas and the lack of resources. Then there is the countries where millions of children are born with AIDs. So sad.

  • 20 1. Human population growth - John Richburg // Jul 18, 2011 at 1:40 pm

    In “Coming to a Planet Near You: 3 Billion More Mouths to Feed,” The United Nations estimates that the world will populate 7 billion people on October 31, 2011. This massive population could do great harm in the greenhouse problem. Burning fossil fuels for energy and the rising demand for agriculture will all add to this problem. Some countries use certain strategies that help the growing population slow down. Rajiv Shah owns the main agency that funds global development and prevents hundreds of millions of unwanted pregnancies. Some people for some odd reason are actually worried that there will not be enough younger people to work to support retirement for older people.

    This article taught me so many new things on the topic of human population growth. I never knew how rapidly our earth’s population had been growing. I had wondered for a long time what would happen when too many people were crowded on our planet, though. I also wondered if we were doing anything to try to help the problem. This article showed me that we are trying. Whether it is something like using strategies to control the population or offering certain programs on different topics that relate to population control.

  • 21 Human Population Growth--Richard Greene // Jul 19, 2011 at 2:08 pm

    In 10,000 B.C. the population of the world was around 5 million people. 2,000 years later, the population had only risen to 8 million. In 1900 at the turn of the century there were 1.6 billion people on earth. Now, there are almost 7 billion, this means the world population has quadrupled in just 100 years. Having this many people in our world today has really helped improve on almost everything. Consider this, in the year 1900 the population of the U.S. was 76 million and the average lifespan was 47 years. Now the population is over 300 million and with more people to discover more medical advances and more healthy ways to do things, the average lifespan of an American is 78 years. With more people able to find more improved ways to do things, American farmers are now harvesting more crops than ever before. The world population is expected to keep booming. With more people to create and invent new things, the world will become more advanced and for the most part, benefit from the increase in population.

    I do not look at the population increase as a bad thing because so many good things will come out of it. The life expectancy will keep rising and peoples lives will keep improving the more advanced the world becomes. It really is incredible how the population has jumped so much in just over a century.

  • 22 William Heartsill - Population Growth // Jul 19, 2011 at 3:53 pm

    My article discusses the possibility of the global population reaching 10 billion by 2100. It states that the current population in almost 7 billion and growing. It says that the population could reach 8 billion by 2023, 9 billion by 2041, and 10 billion after 2081, ultimately ending with the population reaching 10.1 billion by 2100. According to the article, the U.N. states that most population growth will occur in “high-fertility countries” such as sub-Saharan Africa, Asia, Oceania, and Latin America. The article also discusses factors that could affect the rate of population growth. According the the U.N. small variations could have a drastic effect on the population many years in the future. If growth rates were to increase even slightly, the population in 2100 could reach 15.8 billion. Conversely, if the growth rates decreased, the population could even decrease to 6.1 billion. Evidence of decreased fertility can be found by the fact that many countries have aging populations, a pattern linked to decreased fertility. In addition to this, many countries with lower fertility are expected to peak long before the end of the century, leading to lower population growth. On the other hand, increased life expectancy due to research in diseases, such as AIDS, that would prevent much early death, could increase population growth. All in all if growth rates stay the same, the population is expected to increase over time, it will depend on many factors to determine how much.

    Personally, I think that the increase in population is not an extreme problem. I believe that if the planet and the people on it have been able to deal with the increases so far, then this should not be a very large problem. I think that the plant will eventually reach a point when it can no longer take any more people, but I believe we are no where near this point. I believe when the population reaches this point, people will be forced to use radical ideas to deal with the problem, or the population will begin to regulate itself, outside of human hands. Either way I believe that this is not an urgent problem and we need to worry more about the harm caused by the actions of people in the world, rather than the number of people that inhabit it.

  • 23 1. Human Population - Kerrilyn Gibson // Jul 20, 2011 at 12:48 pm

    This article highlights the major findings of the 2010 census. Many of the 10 major points were interconnected, for example, Latino population has increased 43% since 2000 and that racial and ethnic diversity is increasing across the nation. Also, areas of the most increased population density are the Southern and Western United States, and the populations in theses areas has moved to the suburbs of metropolitan areas. Despite the increase in racial diversity across the nation, I was surprised to find that the 11% of the country’s major cities have become “majority minority”, meaning that more than half of the city’s population is considered minority individuals. Another of the major findings is that the United States has the lowest percentage of children (under 18 in 2010) ever documented in America at 24%. This is a global occurrence, as many of the world’s developing countries have lower percentages of children than the US. But, the census bureau is aware that they missed 2.5% of African Americans and 1.7% of children which would only slightly skew the results.
    I was both surprised and unsurprised by the amount of people moving to suburbs. I am always amazed about how many new subdivisions are cropping up, especially during the slumping housing market. Some houses stay on the market for years, but most people opt for new homes in new subdivisions. The reason why this surprised me is that I read about another study done that reported by 2012 there will be more people worldwide living in urban areas, which contradicts the census data. The growth of minorities, particularly those of Latin descent, did not come as a surprise because predictions of this trend had been made previously.

  • 24 1. Human population growth -Andrea Gardner // Jul 20, 2011 at 2:13 pm

    2011 is the year that it is estimated the world population will reach 7 billion. Overpopulation brings on a number of problems such as lack of food, jobs, and places to live. This article suggests that the solution to overpopulation problems is immigration. It suggests that the immigration could be a way to help relieve the pressure of the overpopulation of the poorer parts of the world by havig those people immigrate to the already developed aging world. The article also discusses the importance of education, especially for women because literacy is known to decrease the rate of fertility. It is up to the people now to develop a plan to control the population in the future.

    This article prosed a new idea to to me. I have never really considered the issue of overpopulation and how it could affect our generation later in life and future generations. Although the idea of immigration sounds okay in writing, it would be extremely difficult to carry out in real life. There needs to be a more realistic solution on how to control population without moving people around or putting a limit on how many children people can have like China has done in the past. I think instead of trying to control the amount of people we shoud focus on how to provide and renew resources for the future.

  • 25 1. Human Population Growth - Christina Tam // Jul 21, 2011 at 3:40 pm

    National Geographic sheds light on how the human population came to be so massive, where it will go, and the problems it may present in our future. In the 1670′s a microscopy enthusiast made an estimate that there was no more than approximately 13 billion people living at the time. there were much less people than he had predicted at this time but his actions promoted interest in then human population. Population has grown due to medical advancements which save lives and lengthen the average lifetime. Many thought with the increase in numbers that the world could not physically keep up. However, environment advances quickly followed those in the medical field. With advances such as high bearing seeds and pesticides, the produce could keep up with the population. Soon man tried to take control off the vastly growing human race.In China, government controlled and limited each couple to one child. Others promoted and rewarded sterilization or vasectomies. Eventually in most countries the average number of children produced per family was below 2, which meant that those parents were not being fully replaced. Some studies in India showed that one reason that the increase has declined was that girls who were educated saw more options in there life and may have put off their child bearing years. Today the argument leans less towards population control and more towards decreasing poverty. Less focus on the number of people but instead worry about how much of a carbon footprint a concentrated population emits. For example, some places in Africa, a person only emits a couple percents of what the average american emit.
    I am amazed at how every little thing in the world can increase or decrease the rate at which the population grows. To think that our technology and advances in life effected the rate at which the population grows astounds me. Obviously this could effect everyone of us. Population drives big cities and the economy. The rapid rise in population could either hurt or help our economy in the years to come. I also like this article because it addresses that we need to be aware of our environment and planet conservation efforts.

  • 26 Human Population Growth-Jay Holton // Jul 24, 2011 at 1:57 pm

    Many economists have attributed China’s slowing economy to its evolving demographics. As a result of the one-child policy, a higher percentage of the population is maturing than would be normally. Though the economy is still one of, if not the strongest and healthiest in the world, many are fearful of the dropping growth. With typical growth of the overall market as high as 15%, the recent evaluation at only 9% seems to be a very drastic change, and many experts project that that number will eventually move all the way down to 7%… However, this is still positive growth, and those same experts advise to merely tone down the levels of investment to allow for China to internally build itself back up, which shouldn’t be too hard considering a current population surpassing 1 and 1/3 billion people.

    The fact that the economy growth of China has nearly been cut in half doesn’t really even worry me so much. I’m no economist, but moving from the highest percentage growth in the world relative to its size down half still makes that 7% growth a very large change every year. Even though we live in the U.S. and always have to have the biggest and best, i’m glad there’s another country out there even larger than ours to keep the world economy under control, because if our economy was the best out there, this wouldn’t be nearly as blessed and good of a world to live in…

  • 27 1. Human Population- Casey Bailey // Jul 24, 2011 at 4:21 pm

    My article discusses the estimation that the global population will reach 7 billion by late this year, the causes of this occurrence, and various proposed solutions. High birth rates, better health care, and more sanitation were listed as the main three causes of population growth. All of those are usually considered to be good things, but I’d never thought about how they could backfire before. Unlike the causes of population growth, the proposed solutions to the problems caused by an excess of people are countless. Some ideas include mass sterilization, more education for women, and a higher quality of living for everyone. The first two of these are being tried in India, and both seem to be successful; however, educating women not only leads to lower birth rates, but also gives them more opportunities to create a better life for themselves, so it certainly seems like the better option for most people. Speaking of which, the article also discussed how many people are suffering due to larger populations not because they can’t get enough, but because many governments are focusing so much on this issue that the people who are already here are being neglected. This lead to the idea that a better way to deal with population growth is to focus on the people here first and try to improve their lot. This isn’t the most popular idea, but it seems to me to be the best option. In any case, people seem to be at a loss as to how to deal with this problem. Many can only hope that people as a whole can adapt in order to survive, perhaps by eating less meat and finding alternative fuel sources. However, only time will tell.

    This article mentioned a few things that I’d heard before, like that India’s population will soon outgrow China’s and the main causes of the population growth. I found it really interesting, though, that the world is apparently going through a fertility decline. I mean, it makes sense, because obviously I know that many people aren’t having more than two or three children nowadays. I was just so used to that fact that it never really clicked. I guess it goes to show that the effects of nature really are all around us. Also, I was surprised to read that everyone on the planet could fit in the state of Texas if the population density were the same as in New York City. I’ve been to New York before, and MAN is it crowded! But I never would have imagined that almost 7 billion people could fit inside Texas!! I suppose that, overall, I hadn’t realized that the size of the world’s population was such a huge issue. This is definitely a topic that I would like to look into more during the school year, because it’s just so interesting!

  • 28 1. Human Population Growth - Justin Yoon // Jul 27, 2011 at 1:24 pm

    This article talks about how there will soon be 7 billion people on earth. Many people believe the world is going to overcrowd sooner or later. One of the causes may be child death rate. When more babies die, parents try to reproduce more. Baby booms are also a problem. During world war 2, a baby boom occurred. These have both positive and negative consequences. For a few decades, there are many workers and the economy goes up. But when the “baby boom” children need to retire, it causes a mess. Also Africa’s fertility rate is very high compared to other continents.

    This article showed me that there is a serious problem with population growth and that we may need to be careful when we’re older. I also knew that human beings were growing quickly, but i didnt know we were growing this fast. I have read on Yahoo before that the world is too small for what the human population may become, so this article agrees with what i have read. The bigger problems we’ll face are also in the future. So we need to start preparing for the worst

  • 29 1. Human Population Growth - Adam Munoz // Jul 27, 2011 at 2:15 pm

    My article comes from Kashmirwatch, and it discusses the One Child Policy and its implications in China. This article points out that due to China’s One Child Policy, their economic growth has increased dramatically. The policy allowed China to slow their booming population, and helped preserve their already diminishing natural recourses. However, the policy also created an imbalance of male to female ratio, and much of the population in China are over the age of 50. This large gap may create problems for the future, but many believe it saved China.

    The article makes me realize that while the One Child Policy is harsh; it is one of the reasons why China is so successful today. Without the policy I believe China would have been less successful, and its citizens may be desperate for natural resources. Still, the policy has created problems as well. Many men in China will not be able to find a wife. I believe it is now safe for China to allow for couples to have two children, rather than only one. China’s policy may have helped them be as successful as they are today, but now I believe it is safe for them to relax the policy, and allow for each couple to have two children.

  • 30 1. Human population growth- John Derzis // Jul 27, 2011 at 6:56 pm

    In my article it discussed that world population will exceed 7 billion this year. There are many concerns facing this huge population such as food production concerns and poverty issues. In past decades these issues have not been a major issue because society has dealt with these issues way better than people thought. Scientists were worried with the population doubling in the past half century. But this will never happen again. Several economic factors have reduced the population increase. Food production, city being able to absorb growth, and schooling are examples. The 7 billion mark is a cause to worry but it is nothing compared to the 1960s where population rates were rampant.

    Before I read this article I thought that the 7 billion mark was a cause for great concern. How could the earth hold that many people and with population increasing? After I read the article I realized this is nothing compared to the earlier half century where population doubled. Also these economic factors will reduce the population growth. I had no idea schooling could be a factor to population growth. This article supports an article I read in national geographic which showed the increase in population in the past centurys and that in the futile the population growth will not be as high as the past.

  • 31 Human Population Growth - Allison Williams // Jul 28, 2011 at 11:54 am

    The article “7 Billion” written by Robert Kunzig is about the issues associated with the rapidly growing population. Robert Kunzig wrote that before the twentieth century no human had lived to see the population double, but now they are people alive today who have seen it more than triple. The population grows by 80 million each year and by the end of 2011 there will be seven billion people on the earth. One billion of those seven billion people will go hungry due to the effects population growth has on the earth: soil is eroding, glaciers are melting, and fish stocks are vanishing. Joel Cohen says that how ever many of us there will be and how we will live depends on choices we have yet to make and ideas we have yet to have.

    This article informed me of a lot of different facts and ideas. I never thought about how different life expectancy is today in countries that were just developing decades ago, some of these countries are very much developed now and because of that certain dangers have vanished and life expectancy has almost doubled. I agree with what Joel Cohen said in the article, he said, “see to it that your children are nourished well enough to learn in school and are educated enough well enough to solve the problems they will face as adults.” I also believe that human population growth is causing a lot of different issues, but it’s how the population uses the planets resources that matters more.

  • 32 1. Human Population Growth - David Orrison // Jul 28, 2011 at 5:58 pm

    New York Times writer, Georges Minois, wrote an article dealing with the general term of overpopulation. He describes the concerns and precautions taken over the last couple thousand year. Overpopulation transcended from the philosophies of Plato to the realities of cities in the 11th century. He also focuses on how food production directly correlates with the potential of overpopulation.
    Mr. Minois presented many thoughts I haven’t considered, mainly focusing in ethics and philosophy. He leans toward an stance where the world should keep procreation under regulation until there is plentiful food supply for everyone. Unfortunately, for Mr. Minois this most likely will be impossible to achieve. However, I do agree that certain measures should be taken to relieve suffering.

  • 33 1. Human Population Growth - Devin Valenza // Jul 29, 2011 at 6:42 pm

    Demographics and statistics can’t accurately point out if the world is really overpopulated, it is all due to proportion of land use to that of humans and the distribution of wealth and materials. Philosophers always suggested the limitation of human population due to unforeseeable problems to occur due to lack of control over an over-sized compact civilization. All in all, resources aren’t truly the culprit behind the reason to fear overpopulation but disorder is; when a population becomes too expansive without adequate control and distribution of wealth, society will become more disorderly in time. In the mid-14th century ad, half of the European population was wiped out. This is in due to the lack of technology to administer to the victims of the “Black Plague” and thus represents that since the distribution of wealth and luxury in this time period was so ill-proportionate, these compact societies suffered. In today’s world we have a better distribution of wealth and thus less people suffer as dear from illnesses. Though we have more adapted technology, will we be able to survive at a population of over 10 billion? Demographers state that in due time, the size of human mass will reach around 9 billion and will stabilize there. 10 billion is the proposed limit due to the faults of distribution.

    I have read about theories of overpopulation on numerous occasions- few state that the world will reach much above 10 billion. Whether it be nuclear disaster, widespread epidemic, or whatever other issue one may fathom, the world will always be limited through some natural or unnatural fashion. Seeing how there was an unpredictable population jump in the 1900′s to 6 billion in 1967, demographics is truly unable to predict the size we will grow to and what else may hinder our existence.

  • 34 Human Population Growth- Colby Jackson // Jul 30, 2011 at 3:12 pm

    My article stated that by the end of this year, there will be a world population of 7 billion. Thet population growth is not the biggest problem though. The world has enough resources to last us way through year 2050. Our biggest problem is consumption. The rich consume way to much and if they do not stop, there will be many more problems to come from population growth.

    This article has made me realize a lot of different things. I never knew that the growing population could cause so much damage to the world. My reaction to the human population growth was not a good one. People need to stop over consuming and being greedy. If they do not, this population growth problem will get worse.

  • 35 1. human population growth- mary allison thrasher // Jul 31, 2011 at 1:53 pm

    “Too Much Life on Earth?”- New York Times
    A decrease in global food stock and rapid deterioration brought up the topic of overpopulation again in 2008. there are 218,000 more mouths to feed each day, and 80 million more each year. the global population is now close to 7 billion. Populationists believe that overpopulation is only an illusion, and Malthusians warn everyone of the consequences. Most debates about over population are either religious or political even though there is now plenty of data available. A British economist said that the population growth of a country is always faster than the growth of food production, which leads to overproduction.
    i think overproduction is always going to be a problem, no matter what the year is or the size of the country. Countries are always growing and chances are every part of it aren’t growing at the same rate. i know it can cause problems but i don’t think it is right to control birth rate or anything like that.

  • 36 1. Human Population Growth - Beth Ann Evans // Jul 31, 2011 at 3:02 pm

    The article I read discussed the fact that the world population is estimated to reach 7 billion by the end of 2011. This growth is predicted to continue at a rapid speed in which there will eventually be 9.3 billion humans by 2050. The people are predicted to mostly live in Africa. The rapid population growth has many negative effects on smaller countries such as not enough food, shelter, healthcare, and most of all, not enough money.

    This article made me realize just how big our world is. I’ve never taken the time to think about how many people there are in the world I live in and it baffled me to hear the numbers and how fast that number is increasing. The fact that most of the people that are predicted to exist in the next few decades are supposed to be living in Africa scares me because many places in Africa are places of poverty and they don’t get enough water and food. It really makes me want to help out in any way that I can.

  • 37 Human population growth- Cas Schley // Jul 31, 2011 at 5:45 pm

    According to recent demographics, the world population is expected to exceed 7 billion by late October. In fact, it may keep growing into the next century, exceeding 10 billion. Some experts believe that a good way to curb the population growth, would be to increase the percentage of literate women in the world. Studies have shown that many women who have a college education, are more likely to want small families, and are usually successful at attaining that goal. An estimate even showed that if the rates of college bound women increases, the population could be 8.8 billion by 2050! However, on the pessimistic estimate, the population could reach 10 billion by 2050.
    This article really shcoked me. I had no idea sending women to college could have an effect on the population. I’d never thought about it that way. It makes sense though. And looking at the estimates, that’s a really big difference in the human population. This is actually one of the most interesting things I’ve read concerning the population.

  • 38 Austin Smith- Population Growth // Aug 1, 2011 at 12:46 pm

    Population growth in the world today has become a very rapidly increasing problem. The world’s population is scheduled to exceed 7 billion, which is double that of the 1960s. Many projections have the population at 10 billion by 2100. Many scientists are very scared as well as intrigued about whether or not the earth can even handle this many people. The amount of people may harm the economy, environment, and just the overall quality of life. All of the population growth that will occur between 2011 and 2050 will be primarily in third world countries such as Africa as well as many others. Meanwhile, population growth in the top countries of the world will remain constant. A very disturbing fact in society today is that for every 135 million people born, only 57 million people die, therefore causing a 78 million person increase.
    I believe that population growth can become a very large problem in the future but right now I think we are going at this all wrong. There are many spots in countries that have not even been discovered/ inhabited yet. If people took time to try to live in these places, then over population could be avoided for a longer amount of time. Now don’t get me wrong, I do think we should begin monitoring population growth so that it doesn’t become a great threat but overall, I don’t think it is yet.

    1. Human Population Growth- Sara Goodwin

    The article I read was titled “Population 7 Billion” by Robert Kunzig. The article suggests that by then end of 2011, the world will reach 7 billion. There are several factors to this increase. People living longer and most women right now are in the childbearing years. With this high birthrate, the population could even reach 9 billion before 2050. The population is growing and many scientists ask “how is this going to work?” Many can’t imagine how the world can handle more people. Natural resources are slowly diminishing. Right now on earth, people are going hungry, glaciers are melting, soil is eroding, and many other disasters are happening. And one other challenge we will have to fix is getting people out of poverty.

    In this article, I learned quite a bit of new information. I knew the world was increasing but I didn’t think this much! Im not so sure we can handle this many people. As our natural resources shorten, our population grows. If we are really going to have 7 billion people by the end of this year, I think we are going to have to make a few changes. The world needs to be less wasteful and smarter about using precious resources. Overall this topic was very interesting. It made me really think about our world and how its changing.

  • 40 1.human popilation growth- Christina Rodriguez // Aug 1, 2011 at 3:46 pm

    In 2008 overpopulation increased beacuse of the decline in global food stocks and rapid deterioration of the environment. The global population this has said to be close to seven billion. This number increases every year and is becoming a concern. the increasing numbers just means that we have more mouths to feed, more people to house, and more people to worry about. It is uncertain whether we can support that many people and in what living conditions. It is said that if schools were built to educate children at a rapid clip in all fast growing countries, the population would hit 8.8 billion by 2050. Efforts are afoot to move both education and family planning higher on the global development agenda. The success or failure of those efforts may well influence the future living conditions of the planet.

    I never really thought about our population growing and what it would do to our world eventually. We only have a certain amount of food and territory. If the global population increased to a certain point those two things might be hard to find for everyone. For example my grade at school is a lot bigger than the other grades. When they are trying to set up everyones schedules the school has to make sure that one class does not have too many people in to so that everyone will have a place to sit. All of these thing are just some of the things we have to think about when or population is growing each year.

  • 41 Samantha Fredrick - Human Population growth // Aug 2, 2011 at 12:40 pm

    This National Geographic article talks about population growth specifically in urban areas. Urbanization started to occur nearly 200 years abo when industrialization started to take place. People would move to urban areas for jobs, and now almost one third of the human population lives in an urban environment.

    I learn in this article that cities make a lot of sence to humans. Everyhting is close and easily accesable, but many cities are growing and becoming too overpopulated for their own good. Many people as we know now are unemployed, due to the fact that there are no jobs open. There are too many people and not enough jobs for them to fill. Another problem with urbanization has to do with the wildlife community. If you think about it, the bigger we build cities, the more trees and wildlife we will be disturbing. Common sense. So if we dont stop, they will attack, as we’ve started to see in many big cities such as new york with its diseased pigeons flying everywhere. We need to be aware of our sourroundings and respectful also.

    An article in the Sanfrancisco Chronicle stated that in a recent survey by the United Nation, the population is expected to grow to 10.1 billion people by the year 2100. This immense growth in the population causes concern for many of the poorer countries that seem to already have a heavy population. African nations, such as Yemen, undergo large population growths each year. Just in this century Africa`s population is expected to increase from 1 billion to 3.1 billion. this statistic raises awareness for Africa and other nations with growing populations that already have a difficult time providing food and water to its current population. However specialists say the increase will just make life more difficult and will not affect food supply.
    This article opened my eyes to the impact population growth has on the entire world. While it seems to be a major problem in third world countries, I know it can also greatly impact the United States. With this increase in population, an renewed emphasis in family planning focusing on birth control education and awareness is necessary.

    An article in the LA Times makes the statement that humans may have crowded out the Neanderthals, out numbering them 10 to 1. Research has shown that they lived in the same general areas, sharing the same food and water supplies. It is thought that the modern humans out competed these Neanderthals, thus driving them to extinction. One anthropologist did state that there are to many estimates to definitively say this is what happened.
    This article taught me more about Neanderthals compared to humans. It is interesting to learn about how our human ancestors lived.

  • 44 1. Human population growth - Jaeyong Lee // Aug 3, 2011 at 2:35 pm

    The overpopulation of the humans has worried many people that there wouldn’t be sufficient distribution of the foods and wealth to support 70% of the world population. Overpopulation of the humans has worried people for a long time. In the 4th century B.C. Plato and Aristotle recommended strict control of birth rates by the state because they thought overpopulation means more poverty and injustice among the people. In other hands populationists claim that overpopulation is an illusion because population will stabilize itself when it reaches certain amounts. Before humans invented agriculture they lived as hunters and gatherers and needed lot of spaces to keep ones mouth full. After the introduction of agriculture humans started to live in more populated but still in maintained population. After the Roman Empire, population increased steadily despite the war, famine, high infant-mortality, and epidemics. In the past people were unable to debate about human population because of lack of resources. Earth is capable of feeding 10 billion people but bad distribution of wealth and food has created poverty and starvation on the Earth.
    I had no idea how human population could affect the world with such magnitude. The overpopulation of humans can relate to me because I’m also one of the populations. I agree with the article about how overpopulation can create poverty and injustice because when there are more people more difference between the wealthy and the poor. It showed how in age before the agriculture people lived with only small amounts of people. It shows me human’s natural need to reproduce because during the time of crisis human population still increased.

  • 45 1. Human Population - Bruce Harrington // Aug 3, 2011 at 5:46 pm

    In late 2011, the world population is supposed to hit 7 Billion. In 2100, the world population is supposed to hit 10.1 billion. Almost all of that suspected growth is supposed to be in 3rd world countries, with 49% in Africa. These developing countries will struggle with providing food, shelter, and work for their predicted population growth. Demographicists are predicting a need for contraceptives in a lot more women.

    In this article, I learned that just 50 years ago, the world had less than 3 billion people, and since then, we’ve gained another 4 billion. This effects me personally as when I’m 55, there will be a predicted 9 billion people in the world, and I’m not too fond of a lot of people.

  • 46 Human Population Growth- Jonathan Ashworth // Aug 3, 2011 at 6:05 pm

    This article about the U.N’s recent Global Environmental Outlook which declares the rapid human population growth as one of the world’s foremost challenges. The report was prepared by 388 experts and calls for more efficient use of resources and the reduction of waste. The report identifies issues with the rapid growth such as the creation of dead zones and other such problems.

    I think that reports like this one are very important to take note of. Extreme population growth can cause obvious issues and there isn’t a really good solution to it because one can not simply say sorry but don’t have as many children and expect it to work. So its very important that reports like these get into the hands of emerging engineers and leaders so that we can tackle the issue of lack of resources head on and with ingenuity.

  • 47 Human Population Growth-A'Keria Hutchins // Aug 3, 2011 at 7:28 pm

    In 1677, Antoni van Leeuwenhoek in discovered that animalcules were found in human semen. This inspired him to see how many people lived on earth. He began to research and came to the conclusion that there were 13.385 billion people on earth. As time continued on, historians and scientist began estimating that there were actually half a billion humans in Leeuwenhoek’s day and has doubled every century. By the end of 2011, there will be about seven billion people on earth. The world is expected to reach nine billion by 2045. With this growing population, and a water and food supply shortage, more and more people will begin to starve. It only gets worse from here.

    Before reading this article, I never really thought about how the population would eventually affect the earth. This article has shown me that the world is only so big and the growing population will limit the food and water supply. I think the world needs to make some environmental changes. We should start saving all resources and reusing them. I was also very shocked by a statement in this article that the year 2030 will have the largest generation of adolescents in history that will have children. It showed me that the teen pregnancy rate is only going to get worse, and increase the chances of poverty in the world.

  • 48 1. Human Population - Chad Mullet // Aug 3, 2011 at 11:09 pm

    A man by the name of Antoni van Leeuwenhoek discovered that animalicules were found in human semen inspiring him to find out how many people actually lived on the earth. He investigated and concluded that there were 13 billion people in existence on planet earth today. Historians and scientists alike determined that there was actually half that being about 7 milion people.

    Before looking into this I have to admit I had never given much thought to the planet’s population. I’m surprised to hear that there are that many people living on the same planet as me. I am also concerned about our planet’s supply of natural resources. As human beings of this earth I think we should all go green and recycle everything we use to keep our natural resources available. This article taught me to appreciated the little things that we have such as food, water, and shelter.

  • 49 1. Human Population- Devin O"Rourke // Aug 4, 2011 at 4:31 pm

    My article talks about how demographers estimate that on October 31, 2011, the 7th billion person will be born in Uttar Pradesh. They say this because Uttar Pradesh is the most populated city in India, the country with highest amount of births. The article continues to talk about how just 12 years ago we reached the 6 billion mark, and only 100 years before that the world’s population was 1.6 billion. The 7 billion landmark has raised concerns due to increased greenhouse gas emissions and resource depletion, but the article says the problem is not the high population; it’s the rate of consumption of resources.

    After reading this article, I was a little surprised at the population number. I had known that we were somewhere in the 6 billion, but I had no idea that we were so close to 7 billion. The fact that 100 years ago the population was only 1.6 billion also shocked me. I didn’t realize that the population could have grown that much in that amount of time.

  • 50 1. Human Population Growth- Caroline Wasylenko // Aug 4, 2011 at 9:29 pm

    According to research, the world’s population is expected to pass seven billion in late October, and it doesn’t stop there. The new projections suggested that the human population would continue growing all the way into the next century, topping out above 10 billion. Confirmed research shows that the single biggest factor influencing population growth rates is the educational status of women. If one wanted to slow the rapid population growth in developing countries, the highest priority should be putting more girls in school. Educated women desire smaller families compared to illiterate ones, and generally manage to achieve that goal by the process of family planning and contraception. Calculations show that if schools could be built and children educated in all fast-growing countries, the global population in 2050 would hit 8.8 billion. Efforts are being made to move both education and family planning higher on the global development agenda, and may well influence the future living conditions of the planet.

    I thought this article was very interesting. It shocked me at how fast our population keeps growing and I agree that if more children were educated in other countries, then many girls would think about family planning. If actions are made, we could cut back on the population growth which would help our planet even more. Girls should be allowed to be educated in other countries, because everyone deserves an education. If we don’t do something about it soon, then our population will keep on growing at a rapid rate and more problems will occur throughout our planet.

  • 51 1. Human Population Growth-Maddy Perry // Aug 5, 2011 at 12:11 am

    Human overpopulation is one of the most pressing issues facing the world today. Increased population density results in disease, famine, and war. A major reason for the rapid growth of the world’s population is- believe it or not- charity. When developed countries send aid in the form of food to starving countries without education on contraception and family planning, the countries receiving aid are actually harmed more in the long run. An example of this phenomenon is Ethiopia, where millions of dollars in aid was delivered between 1984 and 1985 with no instruction as to family planning. The population then was 41 million and is now 82 million, and the country is fast approaching another famine. You can see now how aid without education, while fixing the problem for a short time, in the end only increases the amount of human suffering.
    I was completely unaware of the fact that giving aid solely in the form of food and money could actually be harmful to those receiving it. The article suggested mandating that the governments of the countries receiving support also educate their populations on contraceptives and have them readily available, and also to promote smaller families. This seems like a good idea to me because this would cut down on overpopulation issues such as human suffering and starvation. Overall, all aid given should come with adequate education on ways to control the population growth before it escalates even farther out of control.

  • 52 1. Human Population Growth- Landon NeSmith // Aug 5, 2011 at 1:03 pm

    This article describes how an Institute of Medicine in America is doing there part in trying to slow the U.S. population growth. They want to make birth control a free part of health insurance in order to encourage women to prevent unwanted pregnancies. Amazingly, almost half of all pregnancies in the U.S. are unplanned, so this preventative step would not only lower the growth rate but also the number of unplanned pregnancies which in turn would lead to less abortions. Medical experts also believe that this would help women space pregnancies which lowers risk to them and their kids. This plan could possibly be included in the new health care plan.

    I think this is a great way to take care of more than two birds with one stone. And after reading other articles and comments I know that this is a necessary action in order to keep the world’s population in check. I’m glad that they’ve decided to follow through with this considering I’m against abortions and know the harm unplanned pregnancies can bring. I hope that in the future more helpful actions like this will be taken.

  • 53 1. Human Population Growth- Andrew Harris // Aug 5, 2011 at 2:38 pm

    According to my article the global population is expected to reach 7 billion people. In 1999 there were 6 billion people. It is estimated that another 2.3 billion people will be added between now and 2050. 2.3 million people is the same amount of people that lived on the earth in 1950. Estimates from the Population Division of the Department of Economic and Social Affairs of the United Nations say that by 2100 there will be 10.1 billion people. Almost all of the 2.3 billion people projected will live in less developed areas. About half are projected to be in Africa. For most of human history the population has gradually grown. It took until 1800 to get 1 billion people. But, over the past fifty years, has gone from 3 to 7 billion. It is projected that in 2011 135 million people will be born and 58 million will die. This is a net increase of 78 million people. These projections form some challenges. These challenges are overpopulation which can cause disease and famine. Overpopulation would be detrimental to less developed areas. The article also says that developing countries dealing with overpopulation will face difficulties supplying housing and energy to their growing population.

    I was shocked to see how much the global population is projected to grow in a short amount of time. As the article states it took 1,800 years to reach 1 billion people and in just forty years this is projected to be another 2.3 billion people added to the population. This article makes me feel bad for the less developed countries who are going to have little food water, and shelter to provide to their growing population.

  • 54 1. Human Population Growth- Zac Thompson // Aug 5, 2011 at 3:43 pm

    In this article the writer explains how many jobs need to be created per month in order to keep up with the population growth in the country. The article says that approximately 125,000 to 154,000 new jobs would lead to a recovery of the employment population in America. It also says that instead of adding jobs we cut 37,000 positions and are only creating about 117,000 jobs which are only enough to tread water in the unemployment crisis.
    The amount of jobs that the country needs is surprising sounding but the 117,000 in comparison to the amount needed to recover does not make the current job market surprising with the lack of available jobs.

  • 55 Human Population Growth- Jordi Garcia // Aug 5, 2011 at 7:28 pm

    This article was very fun to read. It said that the global population was going to reach 7 billion by the the end of this year. I was really surprised at this because only 200 years ago the world’s population was only 1 billion. (But the reason there was a great increase of population is because of the replacement rate during that time.) Furthermore, in 2045 the global population should reach 9 billion people. It’s also predicted that by 2100 the world population will be 10.1 billion. Many people fear that there will be food shortages, pollution, and such. But there’s a solution to every problem. For example, things like overcrowding shouldn’t be a problem because it’s predicted that in 2050 70% of us should be living in cities.
    The news of the ever-nearing 7 billion milestone is exciting! I am always interested in the future and I’m very curious to find the answer to the question of how will we’re going to handle the upcoming problems! The article says that conditions will be fine as long as we balance our resources. The fact that 5% of people are using 23% of the world’s electricity is going to have to change. That means either people need to use less electricity or there’s going to be more power plants. This may lead to unhealthy environmental conditions if greener standards aren’t set. I’m excited to see how the world is going to handle such a large population.

  • 56 1. Human Population Growth- Greer Maddox // Aug 5, 2011 at 8:21 pm

    Our global population is close to 7 billion today. Each day there is 218,000 more mouths to feed, which is 80 million more each year. Populationists say that over population is an illusion. Karl Marx says, “It’s not the size of the population, but the distribution of wealth.” The prediction is that the global population will be around 9 billion in 2050 and 1o billion in 2150.

    This article taught me a lot about theories. People predict so many things from just the slightest change in population. I had no idea our global population was at its high level that it is at today and I learned how much it is growing each day. What upsets me the most is that the less fortunate countries have even less than we do and its losing many more than we are each day.

  • 57 Human Population Growth-Phillip Moore // Aug 5, 2011 at 9:29 pm

    According to this article the global population is expected to reach 7 million later this year, up from just 6 billion in 1999. By 2050 an estimated 2.3 billion people will be added to the worlds population, and according to the Population Division of the Department of Economic and Social Affairs of the United Nations another 10.1 billion will join us by 2100. Nearly 97% of the 2.3 billion will come from less developed regions of the world, with nealy 49% of that being in Africa alone. This rapid growth of the human population is being caused by more succesful child births and a longer life expectancy that is due to advances in modern medicine. This large growth will most likley lead to a sever lack of food, water, and living space in the locations that will be most affected.

    This article did not tell me much that I did not already know. Ever since humans have been around we have been steadily increasing in number. With todays advanced medicines and science it is no surprise that the population will increase dramatically. I feel as though we should help these under developed countries prepare for the increase as best we can, but other than that what can we do?

  • 58 1. Human Population Growth - Vicki Hill // Aug 6, 2011 at 8:29 am

    The article I read tells how the world population will reach 7 billion this year and could reach 10 billion by 2050. Although fertility rates have decreased in recent years the population still continues to grow at an alarming rate. Mondern medicine and new ideas on sanitation have all helped in the soaring population of the last century, making researchers wonder whether the Earth can sustain this many people. Some countries such as China have decided to limit the number of children per household, but this is not possible in all of them. Others try to promote things such as vasectomies, but these are only available to the people who can afford them. An important point they brought up is that eduacted women have fewer children then ones that lack one. If the population puts more into global education it has the potential of lowering the birth rate across the globe. Even if this does occur, people need to be able to support the huge population that is here today. By making smarter decisions for the planet and lowering our carbon footprint, we can in essence save our planet and have a good place to live for mamy years to come.
    This article really put alot of things into perspective for me. It made me realize how many people are really out there and how limited our resources can seem. Living as a middle class American I dont really realize how many people are in poverty and how that can adversely affect my life. The world can only hold so many people and it is up to everyone to decide when we reach that point.

  • 59 Population Growth- Bayleigh Cook // Aug 6, 2011 at 12:15 pm

    The population in China has been increasingly slow than expected. In 2000, the population was 1.34 million and rose to 73.9 million in the 2010 census. The expected was to be 1.4 billion, missing the margin by about 30 million. The policy in China in 2000 was that each family have one child in hopes to have a more economically stable society. China wavers on wanting to have a larger population so to be ahead in the united nations tally or to have a safer economy.The president is worried that the population is decrease too fast, because the number of childern under the age of 15 is down, but the number for people over the age of 60 has increased. This may cause problems in the distint future.

    This article made me aware that the Chinese goverment is found a way to moniter there population and for the most part keep it under wrap. I think from here the goverment should keep the population stable and, with the economy at a higher point that they have right now, in hopes the goverment will become wealthy enough to allow it’s population to gradully increase.

  • 60 Population Growth-Hunter Dodson // Aug 7, 2011 at 4:24 pm

    As I have just learned the world population is now almost seven million people. The article suggests that we will eventually over populate the earth and use up all of its resources.”We’re already way past the carrying capacity of this planet by a very simple standard,” says Paul Ehrlich.
    I have often thought about these theories myself for many years. I am glad to finally do some research and educate myself on the subject. I think that will all of the advancements in medicine and technology the mortality rate will drop drasticly. People will get older and older and the Earth will keep getting more and more packed. I worry what the solutions may be for this sort of issue but something must be done.

  • 61 1. Human Population Growth – Eunyoung Jo // Aug 7, 2011 at 11:12 pm

    Although biodiversity has positive effects, an ecosystem can actually function with a minimal number of species because so many species occupy similar ecological roles. Therefore, a diverse ecosystem was originally believed to be able to lose a few species without any major repercussions. However, researchers have discovered that human populations are more harmful to diverse ecosystems due to mankind’s selective pursuit of large fishes. These fishes lack the competitors that could replace their roles in the ecosystem; removing the apex predators is detrimental to an ecosystem. Dense human populations are connected to heavy overfishing, land use, and coastal development. Some 75% of the world’s coral reefs are near human settlements, and 82% of countries with coral reefs are expected to double their human populations within the next 50 to 100 years. Although human overpopulation has always been a sensitive topic dealing with science, religion, and politics, a solution to protect marine biodiversity must be found soon. It has been proven repeatedly that the growing human population cannot be supported without the decline of the world’s natural resources.

    I’ve always questioned human overpopulation and how it could ever be solved. Whenever an animal starts to become overpopulated, people have always encouraged the killing of the animal to control its numbers. Take for example the deer. The hunting of these animals has been defended and encouraged due to their vast numbers. However, this method would obviously not be able to solve human overpopulation. Another solution suggested is the restriction on the number of kids each family may have, such is the custom in China. Many people consider this method to also be inhumane, and the question would remain on how to control the number of births everywhere around the world and what to do with any illegal births. Still, it seems that a vast majority are content to leave the problem be and see what happens. It makes me sad to see such beauty like the coral reefs deteriorate due to human overpopulation. Yet, the fact of the matter is, while humans are rapidly damaging nature, there is no easy answer to the problem of human overpopulation.

  • 62 1. Human population growth - Jiwoong Jeong // Aug 7, 2011 at 11:13 pm

    Many demographer and people who work for UN Population Division are worried about human population growth. They predict that the population will reach nine billion before 2050, and as population grows, there will be serious problems that could damage people such as lacking of natural resources. Especially in India, a nation policy adopted in 2000 called for the country to reach the replacement fertility of 2.1 by 2010 and still it’s going on by sterilization. Some people’s thought was making cities and towns livable is important than reducing population. They think that Even if population decreases, the problems are going to remain.
    I did not know the India has high rate of fertility and there are policy about that. There are much more problems occurring from population growth then I thought. Natural resources, starvation, destruction of environment and etc. I can’t imagine what’s going to be happen when the earth explore by high population. Even though human population growth can damage on earth, choosing its fertility and pregnant is person’s won decision and the government should respect and consider each view of the person and find out the way to deal with the problem.

  • 63 Population Growth- Susan Dean // Aug 8, 2011 at 10:59 am

    The world population is expected to reach 7 billion this year. David Lam, the president of the Population Association of America, said that dispite the large population growth, we have been producing enough food and reducing poverty. World population doubled in 39 years between 1960 and 1999. Lam says the population will decline and lose momenteum due to the number of childbearing women right now because of the population growth over the past 40 years ago. There are programs designed to aid in the increased need of food, for example the green revolution which increased food production by 41% in 49 years. Urbanization also has a huge effect on human population growth and the increased investments in education which allow for the increase in population. Lam explains how the challenges facing us now are “staggering. But they’re nothing compared to the challenges we faced in the 1960′s.”
    This article amazed me because it is completely different than any other opinions I’ve heard about the human population growth. It supports the growth and tells us not to fret over the issue unlike everyone else who has been saying the human growth is a bad thing and we do not have enough food and global support. I enjoyed reading this article and it showd me a completely different side to the human population growth issue.

  • 64 Human Population Growth-Will Hamaker // Aug 10, 2011 at 9:41 am

    Global population is expected to soar to 7 billion within this year. The saddest part is that most of the population is expected to come out of some of the poorest nations in the world. The numbers are staggering places like africa where a woman can expect to have as many a 7 children in a life time and India where the gross population is expected to succeed China population by 3 million people. Altough the U.S. and Canada are expected to supply most of the population of the “developed” nations their numbers are simply over ran in comparison to these “developing” countries. With this staggering increase can the earth support the amount of people it will aquire?
    This article shocked and intrigued me. Living in a house of 7 is hardly comfortable in suburban America but imagine the cramped setting of a hut with limited food supply and the threat of rebels waiting at your door. It is hard to imagine the U.S. being a small countries but as the numbers are predicted to grow it is a freightning prospect for me. With even more people in these awful 3rd world settings the idea of immigrating seem grander, and grander a problem the U.S. cannot fully deal with at the present time. With these huge amounts of people how is any government suppose to delegating lands to farming,housing,and preserving nature’s splendor. Healthcare also becomes an issue in my mind not in the way of treatment but as it is only natural medical care itself with evolve keeping more people alive. There are so many questions this article gave me but its hard to find answers to a developing world.

  • 65 Human Population Growth - Daniel Wertz // Aug 26, 2011 at 11:37 pm

    This article is describing the basic state of the urban world. The increase in the amount of urban areas is not just due to the fact that there is a big population growth, but that local businesses, in pursuit of making more profit, buy out the rural land to expand their influence. The highest increase of urban growth are in the world right now is in, you guessed it China. Also along with China, India and Africa fall into this category. With most of these urban areas being along a coast of some sort, a lot of effort needs to be made to keep these infrastructures safe.

    When I read this article I was under the mindset that rural areas are being eliminated in order to make way for the growing human population, but when I saw that it was the corporate world that was driving this growth, it all made more sense to me. It is clear to me that corporate America needs to get a grip on how much land they use vs how much land they really need to carry out their business.
