WATER POLLUTION

1. City growth has always concentrated in the areas near some water supply – rivers, canals, lakes, seas and oceans – because man cannot live without water. The greater is the number of population, the more water it needs. The increase in water consumption on the planet may result in a water shortage in the near future.

2. Since the beginning of civilization, water has been used to carry away different kinds of wastes and garbage. Water has the capacity to dissolve many substances. When dissolved these substances are less dangerous to the environment than metals or plastics. Nevertheless, remaining in the water they can make it poisonous for many forms of life.

3. Huge consumers and polluters of water are industry and agriculture. It has been estimated that about 85 per cent of the water is consumed by industry. To manufacture a ton of paper it needs 100, and a ton of synthetic fibers – from 2,500 to 5,000 cubic meters of water.

4. Industrial and agricultural development is accompanied with the increasing amount of waste materials. It should be mentioned that rivers and lakes are also used as transportation routes, fishing and recreation areas. As a result, more and more waterways are becoming polluted. Lakes are especially affected by pollution because they cannot cleanse themselves as rapidly as rivers or oceans. The wastes are the “food” for water plants which, when growing, reduce the amount of open water and result in drying up of a lake.

5. People have long recognized that we all depend upon the earth environment. But to understand the problem is not to solve it. So, some decisive measures have to be taken to protect the earth’s wonderful and complex environment system which is so easily damaged by man’s activity.
