HABITATS

A brief but effective introduction to the challenges of wildlife habitat preservation, with helpful suggestions for action by young readers. With a flowing, practiced style and remarkably economical language, Patent writes about important ecological concepts, particularly the idea that biological diversity stabilizes life; she also shows how enmeshed we are in the system that created the problems and gives examples of individual and group actions to ameliorate, reverse, or prevent their disastrous effects. Beginning with specific suggestions for turning backyards into mini-sanctuaries, she goes on to inspiring successes like that of the ``Dolphin Defenders,'' African- American children who have created four habitats on vacant lots in St. Louis; describes volunteer opportunities and fund-raising schemes; and lists contacts for more information and ideas. An excellent, well-organized guide, more action-oriented than most books on the topic. Muddy b&w photos; annotated bibliography; source notes (including interviews); index. (Nonfiction. 12-15)
