You need to be
much better informed. Our influence is unprecedented. Our destructive and covetous environmental alterations on a multiplicity of levels rivals the great calamities that resulted in past mega extinctions. Right now species are dying at rates unseen since the late Cretaceous. You can't thump your bible and make this FACT go Bye Bye
. Once you get over your human hubris and sense of entitlement and actually look at what's happening with objectivity it is undeniable that we are precipitating sweeping and irreversible global changes. In short, our activities hardly render us as an "intelligent species". Far from it indeed. Perhaps if you had spent 20+ years in hard science and deductive research you'd have a firmer grasp on these dynamics. Alas.
Whether or not we die out as a species is immaterial and of no consequence to anyone or anything save those we share this blue orb with. Perhaps our selfish and deleterious passage into oblivion would be a GOOD THING for this world. I'm inclined to think so.
P.S.
I recall a fascinating series of sci fi novels I was into some years past:
DUNE and several derivatives, sequels and prequels (Frank and Brian Herbert). One planet, devastated by unbridled greed and absolute environmental collapse precipitated by over exploitation of every resource until the planet was rendered almost an unlivable, oil/SOOT/filth blackened cess pool of depravity was the Harkonnen home world of Geidi Prime; a probable future incarnation of earth if present ravaging continues unabated.
