Water covers nearly 75% of the earth but most of the earth’s water is salty or permanently frozen. Ninety - seven percent of all the water on the earth is salt water which is not suitable for drinking. Only three percent of all the water is fresh water, and only one percent is available for drinking water. The other two percent is locked in ice caps and glaciers. Fresh water is found in ice, lakes, rivers, streams and underground. With all the people on Earth relying on such a small percentage of all the water on Earth, it only makes sense that we must preserve and conserve our water. Moreover, most of the sources of water supply are contaminated by industrial waste or sewage making it all the more necessary to conserve water.
