VII: Read and answer the questions.
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.

 Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater ( the water beneath the Earth’s surface). It is one of the most serious types of pollution.
 Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to water pollution. These factors cause ‘point source’ pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
 Water pollution can have dramatic effects . In many poor nations, there are frequent outbreaks of cholera and other diseases because of people drinking unstreated water. Human can even die if they drink contaminated water. Polluted water also causes the death of aquatic animals such as crabs, fish or birds. Other animals eat these dead animals and may also get sick.
