Scientists studying the carrying capacity of the earth—that is how many of us can live here sustainably—have fluctuated massively. Wild-eyed optimists believe it’s close to 2 billion. Dour pessimists say 300 million. The point is that—and I’m going by the best of those figures—we need to lose 4.4 billion people and we need to lose them fast.

–Author Steven Kotler, writing at Psychology Today. His solution to overpopulation: everyone, everywhere should stop having children for five years. That would chop a billion off the planet’s population. What about the other 3.4 billion we “need to lose…fast”? He doesn’t say, so your guess is as good as mine.
