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.
