Kevin Richardson is known as The Lion Whisperer, because of his unique relationship with lions. It's pretty amazing -- he's hugging, playing with, and otherwise just hanging out with lions in a way that seems insanely risky, but he makes it work. In this short documentary, Richardson explains how he came to know some of his lion friends, and what the threats are to their long-term survival. Have a look, unless you're afraid of lions. (Oh, and there's a long digression on hyenas that's actually pretty informative!)

You may have noticed that this film is also an ad for GoPro cameras. While I've never used one of these things, they seem pretty rugged. GoPro has a bunch of YouTube videos showing how they're used.
