> speaking of climate change, global overpopulation kinda has an impact on it!

You are right, of course; but just to put some perspective to it:

If Thanos-style the population and the CO2 emissions would be cut in half, this would not be enough at all -- we need to get back to 350 ppm (or similar).

I'm writing this to counter the meme that "climate change is Africa's fault, because of their population count".
