Grades 3-6. A trio of authors offer an engaging look at endangered species and what is being done, or needs to be done, to save them. They begin by selecting 17 from the International Union for the Conservation of Nature’s list of the top 100 most endangered species. Each species is featured on a two-page spread that includes anywhere from two to four color photos, a one-page description, and a text box that answers four concerns: How many are there left? Where do they live? What threatens them? And what needs to be done? From Tarzan’s chameleon to the pygmy three-toed sloth and many in between, children will be fascinated, and hopefully alarmed, at the sometimes low numbers of each species remaining in the wild. Includes a chart of the top 100 endangered species with their remaining numbers (if known) and a generous list of further sources.
