> As more children survive to adulthood, women are having fewer kids than ever before. The result is a global population that’s creeping slowly toward middle age.
So people are _already_ having fewer children. Assuming we want to maintain the human species, _someone_ needs to be having children. For diversity everyone should be having _some_ amount of children.
Then of course, it depends on your climate change mindset.
If you think humanity is doomed and there's no way out of this: Don't have children because you think they'll die suffer through the apocalypse.
If you think humanity needs to continue and we will solve this problem: have children because we can avoid the apocalypse.
If you're unsure? Have children. Someone's bound to survive the apocalypse. Maybe it'll be your genetic material.
Personally I think we'll make it through. Life will be different, but we've got a better chance of surviving than humanity has ever had in the past. I think it's more likely that we'll get wiped out by a cosmic event that we don't even see coming.
