This video explains how the wolves saved Yellowstone National Park.

In the 1920s, the government had all the wolves removed from Yellowstone National Park. Without the presence of predators, the population of deer and elk increased substantially.

Due to overgrazing from deer and elk, the entire ecosystem in the park suffered. Then, in 1995, wolves were brought back. And that was when things started to change for the better.

In the video, the narrator explains that while it is true that wolves are responsible for killing many animals, but by doing so, they give life to a lot of other species.

Not only did they reduce the elk population, they also changed the way they behaved. The herbivores started to move away from the areas where the wolves were. Because of this, areas that suffered for many years began to regenerate.
