I think some
had to spend time in front of their portable camera narrating crap. "I'm setting up my shelter this way, down wind, under a strong oak, and hope it keeps the bears that are native to this area away. Also I'm off the ground because I'm scared of sneks. I mean, I know how to deal with them if I have to, but I don't want to." kind of stuff. And, "Oh look, this is the leaf of the Kooka-Kooka plant. You can use it to heal small wounds, cure sunburn, and if that's not enough, it's full of protein, carbs and vitamins. But, as you can see, they're rare, and only one leaf per plant."
It's pretty standard on those nature shows.
