Animals live in many kinds of habitats, located in different parts of the world. This book compares and contrasts these habitats and encourages students to learn how animals have adapted to where they live. Using cause-and-effect vocabulary, the book also explains why many animals are endangered and the reasons their lives are at risk. Students are asked to map the locations of different animal habitats and to come up with their own suggestions on how people can help threatened animals. Teacher's guide available.
