Children's Literature
From the science-themed "Discovery!" series, this informative nonfiction selection about the extinction of various life forms features bold color photographs, interesting diagrams and fact-filled sidebars. The book begins with a history of the extinction phenomenon and goes on to describe species that are continuing to vanish at an alarming rate today. Andryszewski emphasizes humankind's detrimental effects on the environment and how these effects are accelerating the rate at which our planet's biodiversity is disappearing. These activities include industrialization, pollution, the inadvertent introduction of non-native species, the use of poor farming methods, and over-harvesting of flora and fauna. Earth's delicate fragility and the interdependence of life are clearly explained. The final, brief chapter barely scratches the surface of what steps might be taken to quell this disturbing trend. This reference would be a serviceable supplement to a middle or high school environmental science curricula. The text includes a glossary, an index, and a useful list of additional books and websites about this timely topic. Reviewer: Tracy L. Sontrop
