Every year there are more and more people inthe world. Factories turn out more and more products and need more and more water. We live in aworld of water. But almost all of it – about 97% - is in the oceans. This water is too salty to be used fordrinking, farming, and manufacturing. Only about 3% of the world’s water is fresh. Most of this wateris not easily available to man because it is locked in glaciers and icecaps.There is as much water on earth today as there ever was or will ever be. Most of the water weuse finds its way to the oceans. There, it is evaporated by the sun. It then falls back to the earth as rain.Water is used and reused over again. It is never used up. Although the world as a whole has plenty offresh water, some regions have a water shortage. Rain does not fall evenly over the earth. Some regionsare always too dry, and others too wet. A region that usually gets enough rain may suddenly have aserious dry spell and another region may be flooded with too much rain.
