A beautifully illustrated book on endangered species and the opportunities to save them.

Earth has seen at least five great extinction periods, each wiping out up to 95 percent of all living species. They involved massive volcanic eruptions, disastrous meteor strikes and rapid climatic changes. The main point of Endangered is that the sixth great extinction will be the result of humankind's abuse of the environment.

Featuring more than 400 photographs, this book details the plant and animal species that are either endangered or so severely threatened that they soon will be. The authors offer a thoughtful celebration of nature's diversity not scaremongering -- and a plea to rein in current behaviors that negatively affect the planet. Their proposals form a reasoned and hopeful guide to a future world that will be safe for all species. Creatures profiled include marsupials, monkeys, sea turtles, birds of prey, and butterflies and moths.

The extraordinary imagery and the compelling and objectively presented information make Endangered essential reading for anyone interested in natural history....
