Extinction

School Library Journal

Gr 8-12-- A superior account. Stefoff discusses previous extinctions in some depth, effectively contrasting them with the present situation to give a well-balanced treatment of the problems. Beginning with a few examples of human-caused extinctions, she gives a clear idea of the magnitude of the dilemma. She also covers prehistoric extinctions in order to show how the present crisis differs. While presenting some of the more interesting current viewpoints, the author also conveys the current scientific consensus. Most usefully, she outlines up-to-date ideas on ``paths to extinction.'' Particularly effective are the descriptions of the benefits to humanity of biological diversity. Although animal species get most of the attention, some plants are mentioned. Since this is a controversial topic, Stefoff's style of comparing and contrasting viewpoints is particularly appropriate. Christopher Lampton's Endangered Species (Watts, 1988) is shorter and aimed at a lower reading level. The black-and-white illustrations are well keyed to the text; there is a supplementary section of color photos bound into the center. Three boxed articles also interrupt the text. The list of further reading includes recent periodicals as well as books. --Jonathan Betz-Zall, Sno-Isle Regional Library System, Edmonds, WA
