Pollution and Pollutant:
You must have heard about the Ganga cleaning project. Why do you think it became necessary to clean a river as lovely and pure as the Ganga? This is because a large number of people use Ganga water for bathing and performing other rituals and because we have also started having Ganga for disposal of a lot of waste products. If you are living in a big city you must also be familiar with a lot of smoke and dust in the air, the peculiar foul smell from rotting garbage, high level of noise from vehicular traffic and so on. Along with Ganga River being polluted, Yumna waters are also polluted now in fact all river waters are polluted and are made unsafe for human consumption. Air is also polluted because it is mixed with a lot of smoke and fumes, all these are making it difficult for us to breathe. We all know that some smoke is given out by automobiles, factories, and the chullahs that people light. The atmosphere and the soil are also not spared. Lots of noise is polluting the atmosphere further industrial, human and animal wastes are polluting the soil too. Pollution is the addition of any substance to the environment in excess to what is normally present, thereby making the environment impure. The substance which causes pollution is known as a “Pollutant.” A pollutant is harmful to our health, when you wash clothes or bathe in the river; the dirt, soap etc are the pollutants. They make the water dirty or unsafe for drinking.
