Many species, and viruses too, have population-level boom-bust cycles. Maybe humans will self-destruct enough to wipe out a fair number of us and our impacts will dwindle for a few millennia. It'd be cool if other species took the reins for a bit.
What gives me hope is that we shouldn't be the end of evolution, just another step along the way. Maybe someday a better homo will replace us, or AI, or aliens, or just us, evolved more.
I don't think there's anything more we can do about homo sapiens in particular; we've reached our biological limits when it comes to ability to cooperate and think on a global scale. Either we improve the species at the biological level or we're just gonna keep having the same issues, amplified by new technologies but beholden to our primitive minds.
So hopefully we'll get replaced soon!
Life, uh, finds a way :D
