About a fifth of the Earth’s land surface is tundra: cold, dry, treeless, and home to a diverse range of inhabitants including lichens and lemmings, sedges and snowy owls, and dwarf willow bushes and musk oxen. By viewing this program, students can develop a fundamental appreciation for the world’s Arctic and Alpine tundra biomes. The plants and animals that populate tundra environments are clearly identified, along with the adaptations that enable them to live in places where the temperature can drop to 70 degrees below zero.
