Oh I 100% agree. The very optimistic scenario is that a colony on mars is formed with a few people who depend on regular shipments from earth. The realistic scenario is that a colony on mars is not made this century. The extremely, wildly, super-optimistic, not gonna happen style scenario is that a few thousand people live there self-sufficiently; and my point is that, however unlikely such a scenario is, even that is nowhere close to enough, because the vast, vast majority of people would still have to deal with climate change. Moving to mars is not, and has never been, "a solution" on foreseeable time horizons.
