Dancing with Wolves
The Serengeti Rules is an amazing documentary on Keystone Species which are vital for the healthy functioning of an ecosystem, Examples of Keystone Species are Wolves, Pumas, African Elephants, Otters, Starfish; amongst others. Not all keystone species are predators but may be herbivores, the common denominator is that if you remove one of these from the natural habitat the whole ecosystem collapses with devastating results.
Here's a video explaining the impact of the re-introduction of Wolves to Yellowstone National Park in 1995 after an absence of 70 years.
Here is the documentary mentioned.
