Tiny tots may not fully understand Earth Day, but it's never too early to start reading them stories about the environment and the future it faces. Al Gore's PowerPoint presentation may be a little too heavy for their wee brains, but Goodbye Earth, Hello Moon ($13) offers a great starting point for youngsters. A witty and informative read on the current state of our planet, the book provides teaching opportunities as well as beautiful artwork that both mommy and babe can appreciate.

A fledgling tome from Emily Rylander and Gabriel Meil, the two authors prove to be hooked on classics while providing a hip twist to a very important tale. A group of always popular penguins decides to rally the zoological life for a move to the moon after too many afternoons suited for frozen drinks. Swinging monkeys exclaim, "See you later, dear Equator!" while a pack of turtles pull their roll-along suitcases down the beach sadly saying, "Au revoir, Zanzibar." A clever narrative to boot, let's hope these two don't stop at the moon.
