"Overpopulation occurs when a population has exceeded its carrying capacity. The entire planet and virtually every nation is already vastly overpopulated. Africa is overpopulated now because, among other indications, its soils and forests are rapidly being depleted—and that implies that its carrying capacity for human beings will be lower in the future than it is now. The United States is overpopulated because it is depleting its soil and water resources and contributing mightily to the destruction of global environmental systems. Europe, Japan, the Soviet Union, and other rich nations are overpopulated because of their massive contributions to the carbon dioxide buildup in the atmosphere, among many other reasons." http://animalrights.about.com/od/wildlife/a/HumanOverpopulation.htm
If I had a billion dollars to address a global problem, I would disprese it to people in our country to spend it however they please. Life is too short to worry about every problem and to live scared about "what could happen" if we continue our ways. I would spend some of the money on campaigns targeted towards elementary and middle schools, our next generation, on how they could make a difference in the world and make changes in their homes to help the planet.
