Grades 8-12. This remarkable book offers young people the tools they need to become informed, responsible global citizens. While it opens with a tale of Fleischman finding dead bees in his driveway, the discussion quickly broadens to consider the application of critical thinking skills to environmental issues. Rather than advising readers to take specific actions, Fleischman tells them how to evaluate information on topics such as climate change and encourages them to take action by charting a course that seems reasonable. He also discusses techniques to sway public opinion, such as sowing doubt, discrediting scientific studies, and hiding corporate funding of organizations promoting, for example, fossil fuels. The cascade of facts, observations, informed commentary, and sage advice may occasionally overwhelm. On the whole, though, thoughtful readers will appreciate this insightful, refreshing title’s broad scope, use of specific examples, and the many references to related books, documentaries, and online articles, lectures, and interviews. The appended How to Weigh Information section is particularly excellent. A Newbery Medal–winning writer, Fleischman notes that he is no trained scientist, but his exceptional ability to organize the information here and present it articulately makes him a notable citizen scientist.
