Humans are not good at climate timescales. We’re pretty much out of time for preventing the worst affects but those affects are delayed and slow. For example, what if we hit the AMOC collapse tipping point? That will have disastrous results for northeast US and Europe but will take more than an entire human life to manifest. Not a problem for that specific human

Similar with kids. Kids are a choice for your situation in your locale. Despite all the doom and gloom, especially “the circumstances”, civilization will muddle on and it dotes need people. If we recover, it will be thanks to people. If we don’t , there’s still opportunity to live a good life.

Despite it being championed by the nazis, there’s a good argument that we’ve already locked in excessive population loss. Overall population hasn’t peaked yet but as each generation has fewer kids, the peak is in a few decades and the dropoff may be fast enough to be catastrophic. This is similar to climate change in that it operates at timescales humans have difficulty understanding, but it is a problem and now is the time to try to turn that around. And assuming you care about human rights, the shortcuts proposed by Nazis are not ok, and this is going to be a real challenge
