I have to admit, well, I don't, but I'm going to anyway :lol: ... I'm in the same camp as Twinfan and Afghan Dave.
"We" (the human race) are not going to do anything that substantially reduces the "environmental problem" unless"we" recognise what that problem really is... and take, er, "suitable" remedial action. But "we" can't do that in any "logical" or "fair" way because it would not make any sense, to a human, for a species to do it to itself deliberately.
However, circumstances will eventually sort it all out, and what remains, if anything, will start again. I'm hoping I won't be around to be one of the ones that has to start again - that'll be tough - but if I am there, I'm sure I'll rise to the occasion, most of us would.
A successful species in a fixed location will use up all of its resources. If does not adapt or relocate, it will die out. That's it - bottom line. tw@tting about over carbon footprints/whatever is not going to change this.
The big picture is that we all die, sooner, or later... :D
