What is a trophic cascade? And what do wolves have to do with such a thing? This video shows how everything in nature is intertwined--and beautiful.
I dunno about you, but I could listen to the narrator of the video read refrigerator instructions. He has a nice voice, which makes it easier to learn about a global concept. And it doesn't hurt that the video is top-notch as well.
