This is bogus. Hate all this overpopulation nonsense. Every developed country in the world other than the US has a negative replacement rate (births - deaths).

This is bogus. Hate all this overpopulation nonsense. Every developed country in the world other than the US has a negative replacement rate (births - deaths). The developing world is rapidly slowly as well. If I remember right the world only has another 50 years or so of positive growth. Not only that but the demographic skew in the developing world in male-female will likely cause it to slow even faster. The slowing growth and shrinking populations will be the huge problem of this century because our social structure in its current form can't survive a shrinking population.
