Of course, which is why I'm saying we're at a greater long-term threat due to under-population than overpopulation.
Overpopulation, if it really is a thing, is the tiniest blip in human history, and is already correcting itself. The growth rate has been in decline since 1962. My prediction is that the spread and advancement of technology will accelerate this trend so that we reach zero growth by the end of my lifetime.
Nature would have us reproducing at age 14 or something. We'd be dead by 30. As a late father, I understand why we're meant to be immature and naive when we have children; because there is no convenient time to do it, and understanding the implications of child rearing scares most people away.
I'm not suggesting we go back to "nature" only that our social and medicinal "advancement" brings with it its own problems.
