“Mankind is a real smart species. We’ll kill everything here and then fly to Mars.”
Indeed! lol. Just like one of the smartest guys around, Stephen Hawking, said: “humanity will have to move to outer space within a century or become extinct.” Sarc? Nope. Why would we find worth living after we turned the earth into a smoldering hell hole, is a mystery to me. Never mind the techno-fantasy of a Mars colonization.
