GoPro's marketing department has the easiest job in the world — all it needs to do is strap one of its rugged cameras to someone or something doing something exciting and it has an instant ad. In the case of this new video, the GoPro has been attached to an African lioness, and we can watch in first-person as she finds, stalks, and kills a waterbuck. The lioness is tracked by Kevin Richardson, a conservationist who's somehow confident enough to approach the lioness as a friend while she's choking the life out of her kill, capturing the footage on his own GoPro in the process.
