> I'm asking is our current global population level sustainable? It sounds like that's a no. At the current levels, it is not. If we shifted over to renewables then it would be. I find focusing on the population extremely weird, given that the vast majority of emissions are coming from a relatively small portion of rich nations. We could eliminate the entire global south and still tip this planet into disastrous global warming purely based on the emissions of small, rich countries in the north. Put more blatantly, I find that a lot of the discussion about overpopulation is an attempt to put the blame of global warming and our sustainability problems on those who emit the least per capita. There is very little merit to discussions about controlling population size while rich nations continue to depend on fossil fuels to maintain their standards of living.

"If we shifted over to renewables then it would be." How would that help soil erosion, food production/waste? How would that help with other resource use like metals, timber, fish stocks, etc? There is a lot more to sustainability than just CO2. Even looking just at that, where can we get that much lithium, copper, concrete/asphalt substitute, silicon for solar, etc? There are restrictions to the resources we use and process. "Put more blatantly, I find that a lot of the discussion about overpopulation is an attempt to put the blame of global warming and our sustainability problems on those who emit the least per capita." Where was that said? That's not what I'm saying. You still seem to be focused solely on fossil fuels here ("emit"). As nations develop, they will also adopt a more modern and higher consumption lifestyle. This is a global trend that also applies to developed nations continuing to get richer and indulge in having an even better life (eg parents always want more for their kids than they had for themselves, substantial numbers of people want the newest iPhone, look at house size over time, etc).
