   | Full Text Reviews: Booklist - 03/15/2018 *Starred Review* This appealingly informative book highlights the American bison (declared the U.S. national mammal in 2016) and six other endangered species that were saved from the brink of extinction because of the critical role they play in their environments. Reasons for their near extinctions were varied: some were overhunted (gray wolves, whooping cranes, American alligators, American bison), while others were devastated by pesticides (bald eagles), lead poisoning (California condor), or by alien species (giant Galápagos tortoises). The coverage is thorough; in addition to providing information on these animals themselves, the book also highlights individuals who have made significant environmental impacts. Rachel Carson, who exposed the dangers of pesticides, is mentioned, as are scientists and conservationists who are working today to help protect endangered species. Policy changes, too, are explored: the book examines the Endangered Species Act of 1973, which affords such animals with protection, as well as instances where that protection is eroded by reversals of government orders, or government-sanctioned slaughters. Readers will be moved by Castaldo’s appreciation for these animals. Even though each of the species discussed survives today, Castaldo stresses that their survival is not guaranteed. This inspiring and engaging book, with plentiful photographs, includes suggestions on ways to help, online resources, places to see these animals, helpful organizations, end notes, bibliography, an index, and a glossary. - Copyright 2018 Booklist. School Library Journal - 04/01/2018 Gr 5–7—Even in the midst of what Castaldo (and many scientists) dub the "sixth great era of mass extinction," there have been successful efforts to salvage endangered species. Here she profiles seven such initiatives—all animals and all North American, except for the Galapagos tortoises—with quick side glances at several other examples. Some of her selected species, such as the whooping crane (at one time 16 were left in the wild) and the California condor (five, including just one female), really did come close to the titular "brink" and still aren't that far away from it. Others have recovered in great numbers. For instance, the Yellowstone bison herd needed to be reduced in 2017, an event the author refers to as a "Mass Bison Slaughter." Along with brief introductions to condor "nest technicians" and other wildlife workers, the author points out ongoing dangers to animal populations of all sizes, from lead poisoning to "microtrash," and offers shout-outs to such "Eco-Heroes" of the past as Rachel Carson and Richard Nixon. She closes with generalized action notes for young eco-activists and extensive lists of organizations, sites, and information sources. VERDICT Though the "success stories" here are told elsewhere in greater detail, middle school students will find this a topical, timely affirmation that nurturing the planet's biodiversity is not a lost cause.
