I mean, what's notable about the data in the OP is that it raises the possibility that the population isn't going to "slowly rescind"; that it may be a whole lot faster than that given current trends. I don't think anyone itt is saying we need to close schools, or ban contraception and women in the workplace tomorrow (at least I hope they aren't), but just to throw a wild number out, if we knew for a fact that the world's population was going to drop from 8 billion to 4 billion between now and 2200, that would merit some discussion, no? There's no soft landing scenario for that.
200 years ago we had 1 billion people. So we have, for better or worse, managed a 8-fold increase in population over that time but cannot manage a 50% decline?
Makes no sense to me. Why is this going to be such a challenge?
It's not a challenge, it's just that it will make us all worse off in the long run.
Could the Egyptians have built the pyramids with 300 slaves?
Our technological progress would slow down if we had half the number of people. To think otherwise is just being bad at math. Slower technological progress is bad for the species. Somewhere, 20 to 100 years down the road, there is going to be a kid that has his arm replaced by a biological arm grown from his own DNA in a periti dish, and he will wake up with 2 arms instead of 1. I want to be part of that process, even if it is just a drop in the bucket.
Fewer drops in the bucket make it take longer to fill up the bucket.
Tyler Cowen said it better when he said that economic growth is an intrinsic good. Fewer people will reduce economic growth. Jesus said that the man who sees good and doesn't do it does evil. The earth can easily sustain 10 billion people. Solve for equilibrium.
