You could have said the same thing about Europe or America. We could have just stayed in Africa, and the people like you did. But taking the leap worked pretty well, even if it was tough at the beginning.
Actually, why not colonize Venus instead? Sure, it will be hard, at first, with all the sulphuric acid and intense heat and whatnot, but we colonized America, so why not Venus?
We have a record high population, healthier and richer than ever.
Not my downvote, I know what you mean.
Much rather live way out in the boonies, as far away from civilization as possible.
Oh wait . . .
