Too many humans (Score 1)

In "Shadows of Forgotten Ancestors", Carl Sagan and Ann Druyan write of a study done on overpopulation in animal societies. Rats went nuts, apes held out a little longer, and chimpanzees held out the longest. It looks like, thus far, humans hold the record. The point is, there's a lot of this type of thing floating around these days, it seems. Perhaps because of the media we just happen to pay more attention to it, or are just now realizing what's been with us all along. Or perhaps this is all a sign of an overcrowded population doing a bad job of coping with a crowded habitat and diminishing resources.
