The fact of the matter, according to the American Gas Association, there's a 1,000 to 2,500 year supply. Idiot outfits, such as Planned Parenthood and the State Department's Agency for International Development, peddle these doomsday ideas to the world's poverty-stricken people as they sought to do at last year's Cairo summit on population control. There is absolutely no relationship between high population density and poverty. Zaire, with a population density of 39 people per square mile, has to be just about the world's poorest country. Hong Kong has a population density of 247,501 people per square mile - over 6,000 times more crowded than Zaire.
People are valuable.
The Earth is loaded with room and resources to support an even greater population. Even if the Earth's entire population moved to the United States, it would make our population density 1,531 people per square mile. What are called overpopulation problems result from socialistic government practices that reduce the capacity of people to educate, clothe, house and feed themselves. Poor countries are rife with farm controls, export and import restrictions, restrictive licensing, price controls, plus gross human rights violations that encourage their most productive people to emigrate. The true anti-poverty lesson for poor countries is the most promising route out of poverty to greater wealth is personal liberty.
