I don’t think I would anthropomorphize the whole species like that, but I actually think some people are consciously pulling back for that exact “we have too many people already” reason. I believe it to be wildly misguided though. I think it’s a sick mind that perceives their own species as an invasive pest to be exterminated. Humans can be bad and they can be good. If you are dismayed, as I am, at how bad the bad people can be, I would argue that all the good people laying down and dying (either immediately or through voluntary infertility) does not solve that problem. If anything, that might increase the bad-to-good ratio. The actual fixes for that are MUCH harder: 1. Have more kids and raise them to know right from wrong. 2. Have a positive impact on the world to promote doing what’s right.

For instance, Fred Rogers did more for improving the world than 10,000,000 people guiltily refusing to have kids would have.

So did Mother Teresa, who, through her work, both increased the population and inspired others to do good.
