As a counter, and to re-use your own metaphor, this position of "let's forget about mars and only deal with climate change" is equivalent to saying to the man without a parachute "you'll be totally fine if you just put on a parachute". Despite the fact that he's a smoker, has a missile locked onto him, and is busily aiming himself at the lava pool of an erupting volcano as he falls. You seem to misunderstand that nobody here said climate change isn't urgent, or that it should be less urgent than getting to mars. Or that it's not worthy of more resources at the moment than getting to mars. The point being made is that we can and should be doing both at the same time.
