> It's an interesting exercise, certainly, but the kinds of doomsday scenarios where that is likely to occur, humanity as a whole may have much larger concerns than if the people stranded at McMurdo might survive. it's not a doomsday scenario, it's just what it means to be a colony. if it can't keep itself alive it's not a colony, it's an expedition. obviously people are always moving around and moving stuff around, but a colony that can't produce any of the necessities of life just isn't a colony.
