This article fails to address one of the main causes I see people list for not having kids. It's, "Is it okay for me to bring a kid into a world this fucked up?"
A lot of young people are deeply certain that they're going to have to live through an ecological collapse and climate disasters. Why would they want to have a child, and be constantly faced with the fact that their kid is going to have a worse life than them. That their grandkids may not know what seasons were like?
It's also so ridiculously expensive now. It's not worth it.
