With one-third of known species being threatened with extinction, wildlife conservationists are some of the most important heroes on the planet, and Wildlife Heroes profiles the work of 40 of the leading conservationists and the animals and causes they are committed to saving, such as Belinda Low (zebras), Iain Douglas-Hamilton (elephants), Karen Eckert (sea turtles), S.T. Wong (sun bear), Steve Galster (wildlife trade), and Wangari Maathai (habitat loss). Since we all should have an interest in conservation, there is a chapter providing information on ways people can get involved and make a difference. Chapter introductions are by author Kuki Gallmann, actor Ted Danson, actress Stefanie Powers, Congressman Jay Inslee, and TV personality Jack Hanna.
