Living in space is essentially like living in the ocean with all the same environments challenges. We don’t do that and never have because it doesn’t really make logical sense, we have better options available. It lends the question of “why do that?”
Why? Why do we want to live in space colonies? To what end?
This planet will be habitable for tens of thousands of years at the bare minimum if we take care of it, certainly moreso than the vacuum of space.
