Stories of survival have captured human imaginations throughout history. This makes a lot of sense, given the struggles of early humans. There is no shortage of perils that people have had to survive against, and hostile environments to which they've had to adapt. The world is full of danger, especially when it comes to being isolated in extreme environments and being cut off from any form of social order. Deserted islands have been a popular setting for such stories for ages, from Robinson Crusoe to Cast Away, but some more unique challenges come from surviving a much colder environment. Harsh weather, deep snow, scarce food, and the temperature itself can all be a person's undoing.
