Saving Water (Improving Our Environment)

Earth has an enormous, but limited, supply of water. Although no new water ever forms, Earth will never run out of it, either. Still, every single day, people add tremendous amounts of dirt, trash, and chemical waste to the water supply. It's time to clean up our environmental act. By taking a closer look at our water-use habits and how to prevent water pollution, you will realize that even a small action by a single person is a step toward Saving Water. Book jacket.
