It sounds like you have much more faith in the longevity of Earth as a viable life-supporting planet than I do. I'd love to see what data you're looking at that supports such optimism.
I'm just saying we shouldn't abandon or postpone progress on Earth to start an impossible colonization project on Mars.
Any opinion you or I have about how long Earth will remain viable is irrelevant. There's nothing else. Mars and every other body are not viable at all and we have no way to make them so.
