This lyrical, environmentally focused picture book showcases the unique beauty of our one and only universe--its galaxies, stars, and planets--as well as our one and only Earth and the precious life it contains.

Join one girl as she leads her friends to a tree-planting ceremony. Along the way, she explains in simple language the value of the universe and Planet Earth. Readers will see the Big Bang, the Milky Way, all the planets in the solar system, as well as Earth's atmosphere, and the life within it: its oceans, trees, bugs, and seven billion human beings. Finally, the girl and her friends plant a tree--doing one small thing to help their one special planet.

Both informative and inspiring, here is a beautifully written and gorgeously illustrated science picture book about our universe that will encourage young readers and listeners to protect and preserve the environment.
