Five paw prints. Everyday, in the news, you hear reports of the environment being hurt by people who do NOT think about the future. Rarely do you hear of people helping the environment and making the world a better place. I guess this is understandable. Bad events made for good news. But this book is different. This books has selected 12 problems in the environment and the people who are the "heroes" trying to fix these problems. What's nice about this book are the heroes themselves. They aren't only scientists (though there are a few scientists), they are kids, teachers, retired grandparents, Native Americans, and even a masked wrestler. (If you want to know what a masked wrestler has to do with the environment you'll have to read the book.) This book was wonderful. Every chapter explains a problem, why the problem exists, who is trying to fix the problem, and how the problem is being fixed. Not only does the book give all this detail, it is done in a way for students to understand AND enjoy the book. I wish more science books were written in this way.
