I saw this show on TV where the guy was dropped off in the Canadian Rockies with only some camera gear, to "survive" for a week and be picked up. I couldn't figure out the significance of not having a match or something to make fire with. He wound up useing a camera lens (supposably, I don't think it worked really) so he still used a manmade tool.

I didn't get that part and it really bothers me. Also he made a shelter right beside a creek and almost got flooded out. He ate a lot of berries.
