In her trademark infographic style, Gail Gibbons breaks down all the polar bear facts, from where it lives to how it hunts to how it rears its young. Diagrams show a polar bear's den, how a polar bear's stays warm, and much more. This newly updated edition includes the latest information on climate change and other threats to polar bears. Gail Gibbons is the go-to source for early nonfiction for millions of educators and caregivers.
