It appears I answered a question that wasn't asked... I somehow thought you were talking about growing food there. Well that's part of living...anyway outside the food issue there's the problem of transport an area like Alaska would need to rely on imports outside of fresh water. Getting electricity out there would be very hard as well.
So it could be done like imported domesticated farm animals to help with food, nuclear plants for energy and I guess mining could be there export.
Chances are Ra will burn us alive by that point though.
