Water is necessary for life. All organisms contain it, some drink it and some live in it. Plants and animals require water that is moderately pure and they cannot survive if water contains toxic chemicasl or harmful microorganisms. Water pollution kills large quantity of fish, birds, and other animals, in some cases killing everything it affects. So it is very important to have clean water. Water pollution occurs mostly, when people overload water sources such as streams, lakes, underground flows, bays or seas with waste or substances harmful to living beings. Pollution makes streams, lakes and coastal waters unpleasant to swim in or to have rest. Fish and shellfish harvested from polluted waters may be unsafe to eat. People who consume polluted water may get ill if they drink polluted water for a long time.
