The thing I find most irritating about the underpopulation folks is the lack of serious problem-solving.
Encouraging people to have more kids is just one possible solution.
There are so many more possible ones! And probably better ones than creating more humans, which is costly, harms many other goals (e.g. sustainability), and is a solution that just hands over the problem to the next generation.
It seems to me that it's just lazy thinking. Surely we can come up with a better system that doesn't require everybody to biologically reproduce.
