Grades 3-5. Carbon footprint is a term few people knew a decade ago, and now it is used constantly. But what exactly does it mean? This title from the EcoWorks series gives kids a good understanding of the term, but more importantly it shows how each individual’s carbon footprint affects the environment. After explaining what carbon is, how it is released, and how it can be a problem, the book goes on to discuss how and why countries have bigger and smaller footprints, what activities produce the most emissions, and how to calculate one’s own carbon footprint. This also explains ways to help—and what’s beyond individuals’ control. Controversial questions aren’t avoided: “What’s the point of reducing your carbon footprint if more than 1 billion people in China are increasing their carbon dioxide emissions?” Illustrated with stock color photos, the text is occasionally broken up by “Eco Facts” and other sidebars. A thought-provoking overview, and the good back matter will lead kids to more.
This series introduces students to the science and engineering behind eco-conscious practices and products. The accessible format includes well-chosen and captioned photos, and charts and diagrams where appropriate. The books are most effective when they describe how eco-conscious technologies function and are developed. For example, How a Solar-Powered Home Works tells how solar panels collect and store energy and how that energy is converted for use. Students may find How Carbon Footprints Work and How Renewable Energy Works challenging, as their focus is on ideas rather than on practical applications. Bibliography. Glossary. Websites. Index.
