Children take electricity and other energy sources for granted, until one day their community has a power blackout. They come to realize that in lighting homes and keeping houses warm, we are using up natural resources that can t be easily replaced. If we fail to save energy, a time may come when our homes will always be cold and dark.Part of every child s development involves asking questions. Today, some of the most important questions kids ask are related to the natural environment. The enlightening and entertaining four-book Why Should I? series demonstrates the importance of protecting nature. Books present brief, entertaining stories that answer children s questions and feature amusing color illustrations on every page. A note at the back of each book is for parents and teachers, suggesting ways to use these books most effectively.
