The race to save endangered species

From Kirkus Reviews: "Biologist, conservationist and Animal Planet star Jeff Corwin recounts his heartwarming experiences travelling the globe to film rare animals and their devoted human caretakers. The author writes that more than 3,200 species are considered to be critically endangered-some with fewer than 100 individuals-and he estimates that "if the rate of extinction isn't slowed, by the end of the century, more than half the animal species alive today will be lost forever." Corwin experienced one of his most poignant moments in Hawaii, when he saw the puaiohi thrush, one of only 15 individuals left in the species. Although at first sight it looked ordinary, "it . . . transformed into the most vivid bird I'd ever seen. Every little feather, every twitch of its head seemed as vital an expression of life force as I'd ever witnessed."
