Gr 7 Up-Each book is divided into six to eight chapters, and each chapter is introduced with a scenario based in a future time describing an environmental crisis or issue that originated today. The text then explains causes and effects and suggests possible solutions. Each volume has colorful illustrations, charts, and What would you do? sidebars that challenge readers to use their knowledge and analytical skills. Suggested answers are presented in the back matter. Unfortunately, there are no maps to show the location of the countries mentioned. These titles are valuable, timely introductions to the study of global problems, stressing to readers that doing nothing is not an option. Patricia Ann Owens, Wabash Valley College, Mt. Carmel, IL
