Wells explores the characteristics that make Earth capable of sustaining life. Beginning with an imaginary journey through the solar system, a boy and a girl visit the other seven planets and see firsthand why they are uninhabitable, learning some facts about each along the way. Earth is special because of its distance from the sun, atmosphere and water. The final few pages discuss ways that humans have not always taken care of these valuable resources and how they can be conserved. While the overall text has an offhand, casual manner, the backmatter includes several paragraphs that will get readers to think more deeply about some of the subjects raised, such as the planets’ differing orbits and the possibility of finding another planet like ours somewhere in the universe. The pen-and-acrylic illustrations suit the informal tone of the text and feature a cartoon boy and girl being piloted around the solar system by a monkey. Those toward the back get more serious as they promote a conservation message. A good beginning look at the special features that make Earth our home. (Informational picture book. 5-9)
