pollution

Environmental Pollution is the release of harmful environmental contaminants, or the substances so released. Generally the process needs to result from human activity to be regarded as pollution. Even relatively benign products of human activity are liable to be regarded as pollution, if they precipitate negative effects later on. The nitrogen oxides produced by industry are often referred to as pollution, for example, although the substances themselves are not harmful. In fact, it is solar energy ( ...

pollution: Encyclopedia - Water pollution Water pollution or H2O pollution has many sources and characteristics. Humans and other organisms produce bodily wastes which enter rivers, lakes, oceans and other surface waters; in high concentrations these wastes result in bacterial contamination and excessive nutrient loading (eutrophication). Industries discharge a variety of compounds such as heavy metals, and wastewater, sometimes in toxic concentrations, from industrial processes that may also be too hot or too low in dissolved oxygen to support life. Silt-bearing runoff from ...

pollution: Encyclopedia - Haze

Haze is an atmospheric phenomenon where dust, smoke and other pollutant particles obscure the normal clarity of the sky. It occurs when dust and smoke particles accumulate in relatively dry air. When weather conditions block the dispersal of smoke and other pollutants they concentrate and form a usually low-hanging shroud that impairs visibility and may become a respiratory health threat. Dense haze caused by industrial pollution is also known as smog.< ...

pollution: Encyclopedia - Ganges River

The Ganges River (Ganga in Indian languages; Ganges is the Latin form) (Devanagari गंगा) is the major river in northern India and Bangladesh.

pollution: Encyclopedia - Carbon tax

A carbon tax is a tax on energy sources which emit carbon dioxide into the atmosphere. It is an example of a pollution tax, which has been proposed by economists as preferable because it taxes a "bad" rather than a "good" (such as income). A carbon tax, because of the link with global warming, is often associated with some kind of internationally administered scheme; however, this is not intrinsic to the principle, and politically improbable. In 2005, New Zealand intended to become the first nation to introduce a (national) car ...

pollution: Encyclopedia II - Light pollution - Light pollution as a problem

"Light pollution" is a term that is used to refer to light that people find annoying. Some skeptics claim that light pollution should not be compared with "real" pollution, arguing that any instance of stray light has no long term effect. This is because unlike traditional forms of pollution, light pollution is not persistent. The amount of light pollution at any given time is directly related to the amount of artificial light that is being emitted at that time, meaning that if all artificial lights were immediately switched off, the visual ...
