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.
1. What is the leading worldwide cause of deaths and diseases?
Water pollution is the leading worldwide cause of deaths and diseases.
2. How many people die every day by water pollution?
More than 14,000 people die every day by water pollution.
3. How many percent of the water in the cities of China is polluted?
25% of the water in the cities of China is polluted.
5. What phenomena cause major changes in water quality and the ecological status
of water?
Volcanoes, algae blooms, storms, and earthquakes.
Environmental pollution is a term that (1) refers to all the ways by which man pollutes his surroundings. Man dirties the air with exhaust gases and smoke, (2) poisons the water with chemicals and other substances, and damages the (3) soil with too many fertilizers and pesticides. Man also pollutes his surroundings in various other ways. For example, people ruin natural beauty by scattering junk and litter on the land and in the water.
Environmental pollution is one of the most serious problems facing mankind today. Air, water, and soil are necessary to the survival of living things. Badly polluted air can cause illness, and even death. Polluted water kills fish and other (4) marine life. Pollution of soil reduces the amount of land that is available for growing food. Environmental pollution also brings ugliness (5) to man’s natural beautiful world.
One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. But it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.
Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.
