I'm a fan of the Alone series on the History channel. Contestants are dropped off in a remote location and have to survive on their own with minimal gear. All of them are highly trained in hunting, wilderness survival, etc. but only the best (and luckiest) make it past two months.

Humans are not meant to live alone. Even a small group could divide the labor and survive orders of magnitudes longer than a single individual. The most important survival gear is family and community.
