Colonising mars will be a lot like colonising the moon or asteroids, but the gravity will be more human-friendly.
Humans must either become a spacefaring civilisation or go extinct along with all life on earth , full stop. Not working on that problem means dying more or less right away from a geological time perspective. (Relatively) soon earth will be outside of a habitable dust from the sun. Maybe we can move it. But im pretty sure that moving the planet would be harder than colonising mars.
I don’t think anyone thinks that colonising mars means living or even going outside of a pressurised artificial habitat . It would be very much like living in a spacecraft…. But it would be relatively easy to make it really, really big.
I have lived in places where people live in one big building for 6 months at a time, with some of them having not left the building for years. It doesn’t seem that far fetched to me that people could adapt to an essentially indoor environment.
