This is a very real concern. I just don't understand why this isn't a Hot Topic among the moms around me. They can talk about anything under the sun that is harmful to their kids, things that are directly or indirectly caused by climate change, but glossed over climate change itself. I guess it's just one of the things they feel are out of their reach, too bleak probably.
I don't have strong aversion to kids like some hardliner anti-natalist, but this is why I strongly prefer adoption than making babies.
There is a general problem with people not talking about climate, not just on how it impacts health. It's not that it's particularly more bleak than anything else, but that people are afraid of not getting social approval if they do.
