Many of our recent discussions have suggested that overpopulation causes, or at least contributes to, problems such as global warming and economic disparity. Is this accurate?
The world population was 3 billion in 1959. It reached 7 billion in 2012 and is projected to top 9 billion by 2042. Although the rate of growth may be slowing, especially in western countries, the total global population will have tripled in less than 100 years.
Does Earth have enough resources to support all these people? Will we run out of clean water? Will the carbon footprint of each of the 7 billion+ continue to destroy the environment?
Can anything be done to stem the tide? How can the U.S. influence nations with rapid growth to take action?
