Explore the lives of fascinating animals in danger of extinction, as well as those who have been saved. Learn how each animal adapted to its environment, why it is or was endangered, and how people have contributed to the threat to the animal or its habitat. Each book explores possible solutions, including how sustainable development can be used to protect the animals' environment and how the reader can get involved. Features include world maps of habitat areas, population statistics, food webs that show the relationship between the animal and other organisms, and case studies of conservation efforts.
