Yellowstone National Park or ecosystem

This is a video that I just came across recently but it’s actually from several years ago and it’s a perfect example of how I believe that in nature when you upset one piece of the pie, the rest of the pie is upset as well.

The story/video is entitled “How Wolves Change Rivers – video by GrrlScientistover at The Guardian. It’s really a quite amazing video and I must admit I learned a lot about how just the wolves in Yellowstone affect the whole park.

Sincerely-
