Water can be polluted in many ways. Farmers use chemical
fertilizers in their fields to get better crops. Again they use insecticides
that damage crops. These elements are washed away into rivers,canals and ponds.
They get mix with water and pollute it. Sometimes Mills and factories
pollute water by throwing their waste materials into the rivers and canals and
ponds . Steamers, motor, launches and even sail boats can pollute water by
throwing oil, food waste and human waste into the rivers and canals. Unsanitary
latrines in the countryside standing on the bank of rivers and canals also
pollute water. The kutcha drains running into the rivers and canals cause water
pollution. Clean water is safe for us and polluted water is harmful for us. We
should prevent water pollution in order to keep good health.
Or
Water is a major component of our
environment. It is so important for human existence that it is often called
‘life’. We need pure water to drink and for everyday domestic purpose. But
polluted water is harmful for human body. Water is being polluted continually
by human beings in many ways. Farmers use chemicals, fertilizers and
insecticides in their fields. Those toxic chemicals get mixed with water of the
rivers, canals and ponds through rain and flood. Thus the surface water
resource is polluted badly. Again mills and factories throw their toxic chemical waste into rivers and canals. In
rural areas sanitary latrines and drains standing on the river banks are also
responsible for water pollution. The villagers often throw the dead bodies of
animals and rotten plants in the river which add to water pollution. Steamers
and motor launches pollute water by dumping oil and throwing dumps into water.
By drinking polluted water people get affected with various water born
diseases. Cholera, dysentery etc break out in an epidemic form. The government
should not allow mills and factories to discharge chemical waste
indiscriminately. Public awareness should be raised. We should train people how
to keep water pure and clean. We should always remember that pure water is
essential for our life. Through proper management of waste we can minimize the
rate of water pollution.
