The earth’s surface is two-thirds water, yet most of this is undrinkable or unusable because it is either seawater or ice. Of the 1% that is available as fresh water, most is used for farming or industry. Fresh water pollution is the major problem because many rivers and streams are being polluted with pesticides, industrial waste, and sewage. In poor and developing countries, the addition of sewage to the sources of water leads to diseases, and even death.
