==Description==

'''Pollution''' is the introduction of contaminants into a [[natural]] [[environment]] that causes instability, disorder, harm or discomfort to the [[ecosystem]] i.e. physical systems or living [[organisms]]. Pollution can take the form of [[chemical]] substances or [[energy]], such as [[noise]], [[heat]] or [[light]]. Pollutants, the elements of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as [http://en.wikipedia.org/wiki/Point_source_pollution point source] or [http://en.wikipedia.org/wiki/Nonpoint_source_pollution nonpoint source pollution]. The [http://en.wikipedia.org/wiki/Blacksmith_Institute Blacksmith Institute] issues an annual list of the world's worst polluted places. In the 2007 issues the ten top nominees are located in Azerbaijan, China, India, Peru, Russia, Ukraine and Zambia.

[http://en.wikipedia.org/wiki/Edward_I_of_England King Edward I] of England banned the burning of [http://en.wikipedia.org/wiki/Coal sea-coal] by proclamation in London in 1272, after its smoke had become a problem. But the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow.

It was the [http://en.wikipedia.org/wiki/Industrial_revolution industrial revolution] that gave [[birth]] to environmental pollution as we know it today. The [[emergence]] of great factories and consumption of immense [[quantities]] of [http://en.wikipedia.org/wiki/Coal coal] and other [http://en.wikipedia.org/wiki/Fossil_fuel fossil fuels] gave rise to unprecedented air pollution and the large volume of [[industrial]] [[chemical]] discharges added to the growing load of untreated human [[waste]]. Chicago and Cincinnati were the first two [[American]] [[cities]] to enact laws ensuring cleaner air in 1881. Other cities followed around the country until early in the 20th century, when the short lived Office of Air Pollution was created under the Department of the Interior. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late 1940s, serving as another [[public]] reminder.[http://en.wikipedia.org/wiki/Pollution]
