Once on the edge of extinction, the grizzly bears of Yellowstone National Park appear to be thriving. Should they now be removed from the protection of the Endangered Species Act?
The Good, The Bad, and the Grizzly explores this complex dilemma, asking: how do we balance the needs of an expanding human population with the goal of preserving our wildlife as nature intended? Actor Chris Cooper narrates the film.
