Conservationist Jeff Corwin provides an urgent portrait of the wildlife that is teetering on the brink of extinction. From the forests slipping away beneath the stealthy paws of the Florida panther, to the giant panda's plight to climb ever higher in the mountains of China in search of sustenance, to the brutal poaching tactics that have devastated Africa's rhinoceros and elephant populations, Corwin takes readers on a global tour to witness firsthand the critical state of our natural world. Along the way, he shares inspiring stories of battles being waged and won in defense of the earth's most threatened creatures by the conservationists on the front lines. These stories of hope and progress underscore an important message: Our own survival, as well as that of the world's wildlife, is in our hands. The race to save the planet's most endangered wildlife is under way. Every heartbeat matters.--From publisher description.
