The Scientific American
“[A] valuable, far-reaching look at endangered species and global efforts to save them. Determined but far from didactic…Corwin manages to dull the hopelessness and build a strong case for continuing efforts now and in the future.”
“[A] forceful plea for humanity to stop the so-called “Sixth Extinction,” [100 Heartbeats] stress[es] that humans are responsible for the extinction crisis, and only they have the power to stop it.”
Columbia Journalism Review
“Corwin’s conversational, upbeat style makes readers care about the species in peril.”
“Corwin advances the important message that every heartbeat matters.”
"The importance of this absorbing and exciting book is that it bears witness to Earth’s vanishing wildlife by an expert who has actually visited the species, one by one. Corwin reports their status and prognosis, their case histories, and humanity’s chances to save each one—if we awaken in time."
—E. O. Wilson, research professor, Harvard University, and Pulitzer Prize–winning author of On Human Nature and The Ants
"On a warming world, conservation and wildlife protection is an increasingly desperate battle. Here are the stories of some real heroes, who should move us all to real action."
—Bill McKibben, author of Deep Economy

—Bruce Babb itt , former US Secretary of the Interior, and chairman, World Wildlife Fund
"Drawing from his travels to the front lines of the extinction crisis, Jeff Corwin paints a compelling portrait of the many threats facing our planet’s wildlife. Alternately frightening and inspiring, 100 Heartbeats holds important lessons about the impacts we have on endangered animals and what we can do to save them."
—Rodger Schlickeisen, president and CEO, Defenders of Wildlife
"A riveting firsthand account of the lives of endangered animals and the stalwart efforts to secure their future. 100 Heartbeats makes the case clearly: Those present on the planet now have the responsibility, potential, and the opportunity for heroic rescue."
—Thomas E. Lovejoy, PhD, biodiversity chair and former president of the Heinz Center for Science, Economics, and the Environment
"Jeff Corwin is the best nature guide I know. In his gripping new book he pulls us into the life-and-death struggle to save the world's most endangered species. Rather than a collection of obituaries for endangered species, 100 Heartbeats illustrates how committed individuals and conservation organizations can prevent extinctions. This engaging mix of adventure, compassion for nature, and solid natural history is a perfect introduction to a world we are about to lose unless we act now."
—Dr. Eric Dinerstein, Chief Scientist, World Wildlife Fund
