Colonising other planets is a lousy idea; at the very best you could at massive expense colonise Mars, but it would be (a) almost certainly worse than Earth and (b) only s doubling of our resources.

Orbital habitats, formed by disassembling the moon, on the other hand, can give us vastly more habitable area than available on Earth, and the environment can be engineered to be better than Earth ever was.

Recently I’ve become convo bed that other planets don’t have much of a role to play in our future except as a source of raw materials.
