Our nature is one very complex system, and every plant as well as every animal has it’s role in it. The absence of wolves from Yellowstone for about 70 years had a deep impact on the complete ecosystem and things drastically changed. Having no predators to hunt them, animals like deer, thrived and believe it or not that can be a problem.
When they decided to reintroduce wolves to Yellowstone National Park in the United States, back in 1995, they had no clue, how mind-blowing the results will be. It may sound odd, but this actually opened up room for more and more different animals to live in the park, and the craziest part is that the presence of wolves affected the rivers themselves!
