"I generally avoid over-population arguments. But there's no question we're in population overshoot. The catch is we're not going to do anything about it. There will be no policy. The usual suspects: starvation, war, disease, will drive the population down. There's little more to say about that really, and it's certainly an unappetizing discussion, but it's probably the truth. In any case, we're in overshoot and we face vast resource scarcities."
