Wolves killed to many elks. To cows, and sheep it was dangerous living near the park. Wolves are not normally danger to humans. But unless humans hibernate the wolves by giving them food. The return of wolves was a impact on the Greater Yellowstone Ecosystem. Wolves have preyed elks. The Dilemma is, The wolves are back, and may be delisted. I would solve the problem by moving the wolves away from killing animals. Also let the wolves run loose. Put a radio collar on all the wolves, and i would monitor it too. I would put a shock collar on the wolves.
