We aren't killing the planet, we're only making it cringe. We're killing ourselves...the planet will recover fine.
Since the implementation of flight we've covered little over a century. In that time we've developed cellphones and microwaved burritos...so be patient eh?
It's been 100,000 some odd years since we discovered fire, 20,00 since we developed soap, and we spent a couple of millennia without writing or farming, and several centuries committing mass genocides and continental war. So...try to have some perspective.
