Rivers are on of the world's most important natural resources. Many cities are on the large rivers, and almost every country has a least one river that plays an important part in the lives of its people. Besides transportation, rivers provide water for crops, water to drink, and recreation for people who live along their banks And in order to get water for crops, engineers sometimes build a dam across a river and let water become a lake behind the dam. Then people can use their water not only to irrigate fields but also to make electricity for homes and industries. However the water often becomes polluted when cities on river bank grow faster and the number of industries increases. We are learning that it is necessary to keep rivers clean if we want to enjoy the benefits of the natural resources

Water pollution is a major global problem which requires ongoing evaluation and
revision of water resource policy at all levels. It has been suggested that water
pollution is the leading worldwide cause of deaths and diseases, and that it accounts
for the deaths of more than 14,000 people daily. An estimated 580 people in India
die of water pollution related illness every day. About 90 percent of the water in the
cities of China is polluted. As of 2007, half a billion Chinese had no access to safe
drinking water. In addition to the acute problems of water pollution in developing
countries, developed countries also continue to struggle with pollution problems. For
example, in the most recent national report on water quality in the United States, 44
percent of assessed stream miles, 64 percent of assessed lake acres, and 30
percent of assessed bays and estuarine square miles were classified as polluted.
The head of China’s national development agency said in 2007 that one quarter the
length of China’s seven main rivers were so poisoned the water harmed the skin.
Water is typically referred to as polluted when it is impaired by anthropogenic
contaminants and either does not support a human use, such as drinking water, or
undergoes a marked shift in its ability to support its constituent biotic communities,
such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and
earthquakes also cause major changes in water quality and the ecological status of
water.
