I didn't specify a country where people should stop having babies. As far as I'm concerned, every one baby Americans have is more ecologically harmful than 5 babies in Africa.
It's not othering the problem. I think that the people who are already here are already doing enough damage, and that it's enormously selfish and pathologically narcissistic to want to add more humans to the world just to pass along your DNA. Of all the things you listed, I will never consume more than one human's worth of those resources. Whereas for every child you have, you are placing a claim on exponentially increasing resources in perpetuity.
