Water pollution

Water pollution means the contamination of water due to waste disposal, sewerage, industrial dumping of the waste materials, unplanned use of the water resources, building of the houses by the side of the water sources etc. Water is the life blood of the human beings. Without water we cannot imagine the life on the earth. Water gives life not only to the human beings only but all the other living things such as animals, plants, aquatic life etc. The huge source of water on the earth is sea and oceans. The aquatic animals and plants cannot survive without water. But the water of the sea and oceans are not fit to drink for the human beings because they are very salty. The water of lakes, ponds, rivers, well etc are only good to drink. In totality these are the sources of water on the earth.
Water are polluted constantly because of the unwise use of this resource. We should not pollute the water because without it we cannot imagine life on the earth and it is the basic necessity of the human life. For the prevention of water pollution the rivers and oceans should not be made the dumping site of the industry. Rather the waste should be managed properly and they could be recycled. The polluted water causes various types of diseases in the human beings as well as animals and plants too.
