Paul Fleischman offers teens an environmental wake-up call and a tool kit for decoding the barrage of conflicting information confronting them. We're living in an Ah-Ha moment. Take 250 years of human ingenuity. Add abundant fossil fuels. The result: a population and lifestyle never before seen. The downsides weren't visible for centuries, but now they are. Suddenly everything needs rethinking — suburbs, cars, fast food, cheap prices. It's a changed world.  This book explains it. Not with isolated facts, but the principles driving attitudes and events, from vested interests to denial to big-country syndrome. Because money is as important as molecules in the environment, science is joined with politics, history, and psychology to provide the briefing needed to comprehend the 21st century.  Extensive back matter, including a glossary, bibliography, and index, as well as numerous references to websites, provides further resources. Gr 6 Up—Written in a lively style, lavishly illustrated, and timely in its subject matter, this well-researched book is a call to action: now is the time to save our environment. The author describes his technique as getting altitude, or getting above the problem, to see the big picture. Rather than simply offering a list of simple things kids can do to help the environment, he offers more complex solutions for becoming aware of the issues, such as noticing that there is a problem, becoming aware of defense mechanisms preventing people from acting, and learning about systems like capitalism that allow environmental threats to continue. Each chapter, divided into nifty topic-highlighted paragraphs, is filled with historical facts and current events, sidebars, photographs, and definitions of key terms. Backstories, including the oil embargo, the ozone crisis, and the Kyoto Protocol, are presented along with a section on how to weigh information (evaluate the media, follow the money, and check for fallacies). The presentation of facts and the author's positive message are what shine here.
