Yes, but those kids are now more likely to be raised by people who are not aware of the problems, or deny them. "Well-raised" is a key word in my previous comment.
While I think we need to find a way to limit the number of humans and think it's a perfectly fine decision for people to not have children, I will continue to criticize anyone who uses CO2 excessively whether they have children or not.
"Having kids is bad" makes sense as a rule of we assume it kids will have the same footprint as us. But that sounds like another way to admit defeat.
I don't have kids. I'm in my thirties. I really struggle with this idea. I fear that this notion is part of why I will run out the clock on my window to get kids.
All I see is finger pointing when everyone needs to rise to the occasion. I'm falling in that trap myself.
Also, the way the human brain's reward system works, lots of people will say: I have no kids, now I can take an extra far-away holiday.
