You probably don't think much about water, even though you use it every day. There's a lot of water on our planet, but we can only use a small amount of it. Water covers about 70 percent of the earth, but only about 3 percent of it is fresh water. Most of the fresh water, about 75 percent is in the form of ice. In fact, the frozen areas of the world have as much fresh water as all of the world's rivers will carry for the next 1,000 years. The demand for unpolluted fresh water is increasing because the earth's population is increasing.

This eBook includes a brief history of past civilizations that faced drought, a look at the current drought conditions in California, various water reclamation methods, and simple water saving techniques.
