This is a good book to introduce being good to the environment for young children. It could give your young family ideas for Earth Day.
The pictures are fun and the text is short for easily distracted minds. This book goes right to the point so that each idea is made clear without all of the extra information that an older child might want.
Many simple things that a child could do to save the environment are introduced in this book so that everyone in the family (even your youngest) can feel like they are doing their part.
