I think that some of those resources would probably continue to dwindle, even if we all just dissapeared today. That’s a big part of what’s so scary about this. Climate change is progressing beyond what we can “undo”. Now, they’re also seeing greenhouse gases being released from melting ice and soil. The heating won’t suddenly stop if we all died today.

Many living organisms require certain living conditions. Who’s to say that this heat won’t eventually start to destroy the chances of growing most crops? What if these massive forest fires become a lot more common? How many animal species will die? More floods, droughts, storms, and severe heat events are all on our horizon.

I would like to believe what you suggest, but it might be optimistic at this point. We all need to help eachother to survive this, as an entire species (including the rich people ofc).
