Lessons from the wolf

Article Abstract:

The Yellowstone National Park and wildlife service had brought 14 wolves in the year 1995 by truck which made unexpected effects on the park. The wolves helped in reducing the elk population of the park which in turn spurred regrowth of vegetation, the wolves also brought changes in the lives of the park's other animals like ravens, red forces and even songbirds.
