Dwiggins, Don. Spaceship Earth: A Space look at Our Troubled Planet. San Carlos, CA : Golden Gate Jr. Books. (80 p.) 28 cm.
Satellites gave us the chance to look back on Earth and see it as one place. Looking up you don't have the sense of how thin the atmosphere is and how we are clinging to a very large sphere of rock. Satellites allowed us to see Earth as one place as well as see that we were changing the earth. This book concentrated on showing how pollution, erosion , and other problems were visible from space. For the first time we could take the "temperature" of the planet and see what we have done.
