It is the last great wilderness of its kind, a rare and precious haven for some of Earth's most indestructible creatures. Covering more than 500,000 square miles of Chile and Argentina, this wild place is known as Patagonia. At its crown tip is a grand island, Tierra del Fuego, a land as harsh as it is beautiful. This film tracks several species that call this extreme environment home. But the guanaco, condor and Magellanic penguin who share this spectacular place with orcas, parrots and elephant seals are facing increasing pressure from humans. The program details how new conservation models may save them and preserve the wildness at the bottom of the world.
