CIRCLE OF LIFE: THE GREATER YELLOWSTONE ECOSYSTEM - ENDANGERED SPECIES ACT & GLOBAL WARMING
This program looks at the Endangered Species Act; causes of species extinction; greenhouse warming and the consequences to the ecosystem; and the federal agencies that manage the ecosystem and the federal lands found within the Greater Yellowstone Ecosystem. There is also a discussion about cattle grazing in the ecosystem and the challenges it presents to wolf and grizzly management, and considers an important wild card in greenhouse warming that is often neglected: methane.
