A completely unrealistic plan though, to anyone who has thought about it for half a second.

A mars colony is probably doable. A self-sustaining mars colony? For the length of time it would take a completely devastated Earth to recover? Absolutely impossible, at least with our current technology.

Think about the level of supply chain you'd need to get something like a computer or a solar panel made on Mars. Where do you get plastic? Iron ore? Copper? Pure fantasy.

It would still be cool to have a colony on mars.
