Wolves will travel to drink from a river. But could the presence of wolves lead a river to change its behaviour?

In his TED Talk, George Monbiot poetically explains how reintroducing wolves to Yellowstone National Park after a 70-year absence set off a “trophic cascade” that altered the movement of deer, sent trees soaring to new heights, attracted scores of new animals to the area (think: beavers, rabbits, bears, bald eagles and more), and stabilized the banks of rivers making them less susceptible to erosion. Above, see that story set to music — and howls — by SustainableMan.org, who took the audio track from the talk and laid it over beautiful nature footage. It’s a glorious glimpse of how deeply the natural world is interconnected.
