Just because you don't have a massive support crew doesn't mean you're going to die.

I'd recommend you check out a series called Survivorman: http://en.wikipedia.org/wiki/Survivorman

It's a guy who goes out into the wilderness to survive with nothing but some basic gear and a couple of cameras and tripods. Less flashy but way more realistic.

Two different shows, one is about showcasing techniques in extreme situation and feature an ex british special forces with a heavy background in adventuring while the other is about putting one guy alone in a survival situation for a few days featuring a regular guy who has personal interest in survival.

Though they're not with him, Les stroud also has a support crew and a way to contact them in case of life-threatening emergency.

No he doesn't. Most episodes he says that he has to get out on his own. If he missed his rendez-vous search and rescue teams kick into action to go out and find him.

There was one particular episode where he had to find some natives to get him out because he was dying of dehydration. He got sick and had diaharrea and no one was there to help him.
