Around the world many animals face threats to their existence. The destruction of their habitats, hunting, and pollution are all factors that may cause their populations to decline. In Europe, such endangered animals include greater horseshoe bats, sand lizards, and large blue butterflies. This book looks at the dangers faced by these threatened species and describes how people are trying to help them. Illustrated with superb photographs, the book has distribution maps and up-to-date information on status and populations.
