The tundra is the most remote and least inhabited biome on Earth. Few people get to see these remote and foreboding landscapes. Readers will learn what can live in these harsh environments and why such an unwelcoming place is essential to all life on Earth. Vibrant color photographs help students get a complete picture of the tundra. "Compare and Contrast" and "Think About It" boxes allow readers to put what they have learned to use and expand that knowledge.
