As Arctic temperatures continue to rise and glaciers grow smaller, most people have become sadly aware of the plight of the polar bear. But what about the rest of the earth's creatures? How are tigers, alligators, wolves, and monkeys affected by climate change? In "100 Heartbeats", conservationist and family television host Jeff Corwin provides an urgent, palpable portrait of the animals that are only a few heartbeats away from extinction. Corwin brings to life the unique struggles of species such as the Asiatic lion, whose dwindling members are fighting for survival; the harsh lessons learned from animals we've lost, like the mouth-breeding frog; and, the inspiring stories of successful conservation that have helped to save the sea otter and other animals. And while Corwin voices a warning about the catastrophic state of our natural world, "100 Heartbeats" ultimately provides a message of hope and possibility. This is Corwin's call to arms, and his ultimate goal is to inform, enlighten, and empower readers.
