You might think that wolves are nothing but a small part of the eco system. However, you’ll never believe what they were able to do change the eco-system of Yellowstone National Park. 70 years ago, this park was beautiful and the eco-system was balanced. But then the wolves disappeared because of human negligence and natural causes, and the park started deteriorating. Now experts reintroduced wolves in this park and the change they brought is just unbelievable.
At first this small pack of wolves started hunting down the elks and deer in the park. It gradually decreased the number of elks and deer, which in turn flourished the greenery in the park. As the grasses started to grow greener and the trees grew beautifully, small creatures like beavers, rabbits, birds and many more started to appear. They even changed how the rivers flowed.
