When the earth came into the existence the pollutants were very few. The amount of pollution  has increased due to the increase in population and decrease in the natural resources. Their rates have increased many folds and have an adverse effect on the human health. It also leads to the financial losses. Basically  pollution  is defined as an unwanted  change  in the  environment  which involves the  physical , biological and  chemical changes  involving air, water and land which affects the human life in one way or the other. It also affects the natural resources, living conditions and the cultural aspects of the humans. It can  be natural  or manmade. The natural  pollution  comes from the natural gas,  volcano eruptions , soil erosions and cosmic rays. The natural  pollution  is less in concentration as compared to the manmade  pollution . In the contamination there occur harmful organisms which cause the disease.

Pollution is when something is added to the environment that is harmful or poisonous to living things. Smoke in the air from factories is a type of pollution as it is bad for the lungs when breathed in. Sewage in drinking water is another type of pollution, as it can make people ill because it contains germs and viruses. People living next to a building site where there is too much noise can become sick as they cannot sleep or relax.
