"When we try to pick out anything by itself, we find it hitched to everything else in the Universe." - John Muir

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable "trophic cascade" occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix.

NOTE: There are "elk" pictured in this video when the narrator is referring to "deer." This is because the narrator is British and the British word for "elk" is "red deer" or "deer" for short. The scientific report this is based on refers to elk so we wanted to be accurate with the truth of the story.
