Save Our History - Season 1 Episode 21 Yellowstone National Park
Our first and foremost national park, Yellowstone was established in 1872 by Congress. Today, it encompasses 2.2-million acres and draws over 3-million visitors yearly. But it's under constant threat from pollution, urban encroachment, and the same tourists that have made it so valuable. We join ecologists, as well as the National Parks Service, in their search for ways to preserve this vitally important ecosystem, while keeping it available to visitors for years to
come.
