They have done all the things we wish we could do. This book will make young scientists aware of the super powers of nature and may inspire some to find ways to change the future of Earth!
Animals have become extinct for many reasons. The most famous example, the extinction of the dinosaurs, may have been the result of an asteroid hitting Earth or an Ice Age freezing them to death.

This fascinating book introduces and explains the designations of endangerment from extinct in the wild to vulnerable. Children are also introduced to fossils as a way of learning about animals that lived long ago.
