I dont think theres gonna be some catastrophic event thats gonna "end the world". I think with time we will feel the impact of sucking the earth and our natural resources dry that will create a chain of events which, i believe will systematically, because of dwindling resources, thin out population ending in famine and a giant bow on top of becoming a barren unlivable planet. Regardless of when or what it might be Im not worried about. Im worried about my dog not suffering and having enuff weed and fire to go out in fucking style. bring it on.. cant complain. we did it to ourselves.
