Just because we always have doesn't mean we always will.
We're managing our planet like a chronic drunk driver who's somehow never had a collision. "It's fine, I do this all the time!"
All it takes is one 'not fine' and the story's over.
I just hope whatever emerges from the ashes evolves to be a species that's less of a dickhead than humans. ...assuming anything emerges from the ashes; that isn't a guarantee either.
