Discusses why the earth's protective ozone layer is shrinking, the impact of the additional ultraviolet radiation coming through the atmosphere, and what steps being taken to alleviate the problem

Reviews

Grade 4-8?Pringle involves readers in the exciting story of how dedicated scientists throughout the world struggled to gain understanding and evidence of the thinning ozone layer; the tug-of-war between industry, environmentalists, and governments; and the drama of media coverage of the crisis. Beginning with an explanation of the ozone molecule and continuing with a Jekyll-Hyde analogy of the positive/negative nature of it, the author clearly sets the stage for students in pursuit of answers. The organization is excellent, with the clear message that in order to address the scientific, as well as the philosophical, questions, one must first understand the facts. Technical terms are well balanced with everyday examples of how the changing ozone can affect humans, animals, plants, and the supply of natural resources. Crisp black-and-white photographs, diagrams, and maps illustrate the text. Concluding chapters offer suggestions for taking action and include addresses for government agencies and environmental groups. Youngsters will enjoy the behind-the-scenes details, as well as learning about scientists who pursue the investigation with all the dedication of crime-stopping detectives. An enlightening discussion of the issue.?Sarabeth Kalajian, Venice Public Library, FL
