Still we must be vigilant that our solutions don't accidentally (or intentionally!) factor down to "there's too many humans, lets starve out some of those poors".
I completely agree with you about that. There are a number of climate change solutions (particularly around population control measures) that land uncomfortably close to eugenics. As a side note, my wife and I are not having children precisely because of the climate crisis. We don't want to bring children into a world that is looking increasingly unsurvivable.
