Illustrating the relationship between animals and people, and the struggle to survive that many animals face day in day out, this book reveals how many types of animals are in danger of extinction as they are hunted for their skin, teeth and bones and how other species have become threatened because humans have destroyed their habitats. All sections of the animal world are represented, from butterflies, beetles and bugs to snakes and larger mammals - bears, big cats and elephants. The text explains what is currently being done to protect these endangered animals and how research is helping experts to understand what can be done to preserve them and their habitats in the future.
