Human Population

            Human population is the global issue that I chose to research. The reason it is important is because of overpopulation. Overpopulation is when there is an excessive amount of people, in this case, in the world. “While at the beginning of the century the Earth had an estimated 1.6 billion inhabitants, this number grew to 6.1 billion by the end of the century, and further significant growth is a near certainty.” (Lutz & Quiang, 2002)With overpopulation things like global warming, pollution, habitat loss, more restrictions, extinction and many more issues likes these follow it. All of these issues are very bad for the environment and can cause serous harm to the Earth in the future. Questions that emerge from preliminary research are questions like how do we change overpopulation and how can we deal with it now? I think that overpopulation is definitely an issue that will take a long time to fix if possible. There will have to be new laws created and a lot of innovation to current products used. “Carbon-dioxide levels are now greater than at any time in the past 650,000 years, according to data gath- ered from examining ice cores. These increases in CO2 correspond to estimates of man-made uses of fossil car- bon fuels such as coal, petroleum, and natural gas. The global climate computations, as reported by the on- going Intergovernmental Panel on Climate Change (IPCC) studies, indicate that such man-made CO2 sources could be responsible for observed climate changes such as temperature increases, loss of ice cov- erage, and ocean acidification.”(Busnell, 2010) Fixing the overpopulation will relieve so much all around the world and help it to be a better place for human existence to continue to live in.
