The Americans were the first to bring the idea of a national park to the world: Back in 1872, the area of Yellowstone National Park was designated a national park by the US Congress — the first national park ever to exist in the world.
Among the most famous national parks worldwide are, besides, Yellowstone National Park, Denali National Park in Alaska, Waterton-Glacier International Peace Park and two parks in Canada: Kluane National Park and Reserve and Banff National Park.
Each episode of this series is dedicated to one jewel of these natural wonders. For one year each, the filmmakers accompany the rangers and scientists who have dedicated themselves to the preservation and exploration of this unique and beautiful nature that is threatened, especially by climate change.
