Pollution is now a commonplace term that our ears are attuned to. We hear about the various forms of pollution every day and read about it through the mass media. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals, and humans to survive as the air becomes dirty. The growth of urban population and the formation of big cities - megacities put the urban environment at risk of serious degradation. The supply of clean water, housing, and trees has not been able to keep up with the development of the population. Air and water pollution increases. Social evils and urban social management are increasingly difficult.
