Pollution is when something is added to the environment that is harmful or poisonous to living things. Smoke or dust in the air 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 contain germs and viruses. People living next to a building site where there is too much noise can become sick as they cannot sleep
Environmental pollution or ecological disorder is now a global phenomenon with regional variations in its nature and extent. Now, when there is anxiety and debate on this startling issue, countries are entangled in accusing one another for polluting the environment. The rich and powerful nations, which are the biggest consumer, hold that the poor countries are responsible for environmental pollution.
Environmental pollution is directly linked with consumption level and living pattern. It is, therefore, also linked with the level of economic development and poverty. Pollution is the result of an unmanageable amount of residues and wastes due to the high consumption level, emissions from chimneys of industrial units, smoke from motor vehicles etc.
