Parachuting back to highlight a really bad article in Vox saying it's okay to have kids (no discussion of how many is okay, so I guess a quiverfull is fine) regardless of climate change.
Bad arguments include saying that the only climate emissions that matter are the ones that happen in the next decade (and still not noticing that having kids would affect that figure). My favorite though is a cute story from the Bible that said Israelite women in Egypt wanted children when the men didn't, and one of the kids ended up being Moses. Literally magical thinking at work, "as an expression of hope".
There is the tired-yet-legit argument over personal action versus government policy, but you're really choosing the worst facts for your side if you think personal action of having (an apparently unlimited number of) kids is okay for climate. This isn't about skipping straws.
More hangovers from the horrible racism that afflicted past efforts to care about population growth.
So I'll stick with my recommendation instead - vast long-term decrease of human population on Earth, and virtually unlimited numbers off-planet.
