How Wolves Change Rivers
George Monbiot’s five-minute film traces how the return of wolves to Yellowstone changed animal behavior, vegetation, riverbanks, and the shape of the rivers themselves.
Change moves through a system.
George Monbiot wrote and narrated this five-minute film; Sustainable Human produced the music, sound, and images. It follows the reintroduction of wolves to Yellowstone and the chain of changes that followed across animals, plants, riverbanks, and waterways.
I return to it because it makes a systems idea visible: changing one relationship can alter conditions far beyond the point where the change began.
