Watch Extreme Environments Season 1 Episode 18 Online

Areas of wilderness are parts of the world that have been left untouched by modern man. Some places have survived because they are too harsh to be inhabited by civilization. Others have survived because people have worked hard to preserve their natural beauty. High in the Himalayas, Indian’s Valley of Flowers National Park is one of those protected as a World Heritage site. Known for its meadows of Alpine flowers, it represents a transition between forest and mountainside. The last great wilderness is Antarctica, which belongs to no country and is protected from exploitation by its subzero climate.
