Nature: Bears of the Last Frontier

Bears are an ultimate icon of the wild, regarded as among the most successful wild animals on the planet. Three of the eight bear species in the world -- brown bears, black bears, and polar bears can be found in Alaska, one of North America s last truly wild frontiers. Nature joins adventurer and bear biologist Chris Morgan on a year-long motorcycle odyssey deep into Alaska s bear country to explore the amazing resiliency and adaptability of these majestic animals as they struggle to make a living in five dramatically diverse Alaskan ecosystems: coastal, urban, mountain, tundra, and pack ice.
