> World fertility rate is still somewhat above replacement, World fertility is only above replacement because of a few hot spots that have high fertility. As those cultures are converted to something more western-looking, fertility plummets. You're postulating that, somehow, this will reverse and those places will convert the west to something not-so-western-looking, or that they'll fail to convert. Both of these seem very unlikely. Do you see any trends or evidence that either of those will come to pass? > Low fertility doesn't lead to extinction in a few hundred years. Let's say the average is one child per woman (even places like Japan are above this), then it still takes 23 generations to reduce the global population to a thousand people, and a further ten generations to reduce to one. It's a compounding effect. When there are only one thousand people, you still expect those who grew up in such an environment will still somehow manage a fertility rate of 1.0? What will allow you to hit 1.0 and plateau at that for 33 generations? > Nobody really understands why fertility rates drop with wealth, That's easy to understand. As individuals can be mentally ill, so can large groups of people be so collectively. And collectively, the world is neurotic. > so it's not weird to think that further changes could Yes, miracles will happen.
