A. The world's population right now is around 7 billion people. Geographers estimate the world's population will go from 7 billion to 9.5 billion by 2050. It is predicted that around 97% of population growth will be in developing countries. Our future population is dependent primarily on fertility rates. If our total fertility rate stays at 2.5 children by 2050 our population will reach 12 billion people. On the flip side, if our total fertility rate goes down to 1.5 our population will go down to 8 billion by 2050. Japan is a more developed country with millions of people yet there aren't enough people working. Japan is experiencing a decline in birth rates there are only 1.3 children per woman. On Japan's population pyramid the elderly…show more content… Thomas Malthus believed that the human population rate would largely outsource the food supply. Many geographers believe Thomas's argument is unrealistically pessimistic. Geographers argued against Malthus's beliefs on the topic of population growth. While Malthus believed that the growing population would outsource the food supply, geographers believed that a greater population would mean greater production of food. With a growing population this also means a greater demand for everyday necessities, which creates more jobs for people. The people who are most against Malthus are the Marxists because they argue that the world produces enough resources to meet everyone's needs, but the wealth isn't distributed equally. One thing that supports Malthus's argument is that population is growing rapidly, but he didn't account for the amount of rapidly increasing birth rates in developing countries due to medical technology. However there are several things though that do not support Malthus's argument such as the overall food production has increased during the last 1/2 century more than Malthus predicted. Malthus also didn't anticipate for better growing techniques and technology, higher producing seeds and the cultivation of more land which helped expand the food
