The thing I don't get is: I have to imagine that no matter how badly we screw up Earth, any technologies that we build to allow us to survive on Mars could just as well be used to make Earth "livable" again for less cost. Worst-case, it's pretty much the same thing without a rocket launch.
I mean I do get the idea of defense against a cataclysmic event like an asteroid strike or wide-scale nuclear war but... That seems to be the only realistic reason to want to colonize Mars.
- outworlder 4y ago> no matter how badly we screw up Earth, Really? Our weather can potentially get incredibly violent and completely obliterate any structure we can conceivably make. There's a limit on how badly we can mess up. I think we should be focusing on establishing a space industry (or moon bases) before we even think about mars. And at that point, unless it's for hiking, we might find that we don't need planets anymore.
