Kids can count reasons to love the planet and ways to protect it in the pages of this conservation-themed book. Gentle verse reminds the reader of Earth's beauties--starting with "one wide sweeping sky, two honey bees" and continuing all the way to "ten fields to plow." The text then starts counting backwards, listing simple ways children can help, such as reducing waste and reusing items. The conclusion takes us back to number one with the book's key message: "One Earth so beautiful. Remember--only one." At once celebration and challenge, this book will encourage children to take better care of the planet.
