Description: The story of how wolves changed the course of the rivers of Yellowstone National Park is a story that shifts the narrative of how nature itself works. In a very real way, the story of how wolves change rivers animates the web of life in a way that is impossible to ignore. Instead of viewing each individual species separate from the whole, people begin to see the orchestra of nature come alive. Something about this story just feels true. With the original video on YouTube having been seen over 43 million times, this video has been credited with changing the hearts and minds of people about wolves, helping to turn them from a sinister villain to an ecosystem engineer. Beyond ecosystems and wolves, this video shows that the world is far more interconnected and co-dependent that we imagined. Only when all of life thrives can humanity thrive. There is no separation. This video went viral nearly 10 years ago and has been used in countless classrooms and museums around the world to teach people the value that every species brings to an ecosystem. We decided to update the video using HD footage.

Atrophic cascade is an ecological process that starts at the top of the food chain and tumbles all the way down to the bottom. And the classic example is what happened in the Yellowstone National Park in the United States when wolves were reintroduced in 1995. Now, we – we all know that wolves kill various species of animals, but perhaps we’re slightly less aware that they give life to many others. Before the wolves turned up – they’d been absent for 70 years – the numbers of deer (because there had been nothing to hunt them) had built up and built up in the Yellowstone Park and despite efforts by humans to control them they’d managed to reduce much the vegetation there to almost nothing. They had just grazed it away. But as soon as the wolves arrived, even though they were few in number they started to have the most remarkable effects.
