Water is very important for all human 

        beings, animals and plants. Chemicals and other

        harmful substances pollute water. This  would

         result in the pollution of streams, lakes, river

         and seas. Sever  water pollution can kill large

         numbers of fish and other animals. People who
         use this polluted water can fall ill.
                      Humans polluted water in many ways.

          Insecticides  and fertilizers used in large quantities

          In  forming are some examples of ways of polluting 

          water. When it rains these chemicals flow into streams,

          lakes and rivers. Harmful chemicals, gases and waste
          materials are also sometimes released from industrial

          factories into waterways.

                        We should control ways of water pollution.

          We can do this by helping to keep our sources of water

          clean. In  agriculture we should not overuse chemicals.

          Another way of preventing water pollution is ton build

          cleaning treatment plants in factories. If we stop throwing
          waste into lakes, rivers, and seas  they will  be clean and

          beautiful  forever.
