Although Leonardo DiCaprio is better associated with the “Wolf of Wall Street” than with actual wolves, he is an activist for global conservation, donating over $15 million to environmental organizations.His newest development, “American Wolf,” hints that his role as a wildlife activist may be expanding to that of wolf conservationist. The book behind “American Wolf,” which is being written by Nate Blakeslee, tells the story of a female wolf of Yellowstone Park, fondly called ’06 by her human admirers.
