> 1% of earth's resources to have a chance, of let's say super pessimistically, 15%, of actually surviving as a species That would be a good investment, yes. Unfortunately, a Mars colony doesn't realize that investment. There wont be a self-sustainable colony on a planet, where even the planets gravity well (which we cannot change, unless someone has SG1-Asgard-level technology lying around) prohibits long term survivability of a species that evolved in a gravity well almost three times as strong.
