After nearly 70 years without wolves, they were finally reintroduced in the Lamar Valley of Yellowstone National Park in 1995 and that was the beginning of the change of nature.
The effects of these animals being brought back to their natural habitat were way more striking than anyone could have ever expected. Not only did they transform the entire ecosystem of the national park, but they also changed the course of the rivers. And it all started with the wolves doing what they do best; hunting the deer.
Once the population of deer reduced, the vegetation was brought back to life and it triggered other animals to reappear.
This video is by far the most fascinating thing we’ve ever seen as it shows the incredible way in which nature works.
