<onlyinclude>'''Air''' is a mixture of several [[gas|gases]] that is a precious resource and a necessity of life. Pure air is completely invisible and odourless, however [[pollutant]]s in the air can cause it to have a coloured tinge or odour.</onlyinclude> The importance of clean air as a resource should not be underestimated as humans use an extremely large amount of air simply to stay alive. Adults breathe in approximately 10-20 cubic metres of air daily - the equivalent of about 20 000 breaths.<ref name="RE1">Government of British Columbia. (May 19, 2015). ''What is Air?'' [Online]. Available: http://www.bcairquality.ca/101/what-is-air.html</ref>

==Composition==
Air makes up a large portion of the [[atmosphere]] of the Earth. The atmosphere is around 1000 [[kilometer]]s thick, but the bottom two kilometers is where most of the air is concentrated - along with a large amount of the air pollutants. Although the composition of air doesn't change much as you travel through the layers of the atmosphere, the concentration of air decreases drastically as you go up in the atmosphere.<ref name="RE2">NCAR. (May 19, 2015). ''Air Composition'' [Online]. Available: http://eo.ucar.edu/basics/wx_1_b_1.html</ref> Pure, dry air is composed of 78% [[nitrogen]], 21% [[molecular oxygen|oxygen]], and less than 1% of argon, [[carbon dioxide]], and other gases including varying amounts of [[water vapour]].<ref name="RE1"/>

==Air Pollution==
Since air is such an important resource, [[air pollution]] is a significant concern. Issues surrounding air quality - namely urban [[smog]], [[acid rain]], use and production of different [[fuel]]s (namely the use of [[fossil fuel]]s), and [[global warming]] - have become more prominent in recent years. Although air pollution is a significant issue in places around the world, with places like China issuing air quality warnings that advise people to stay indoors due to poor air quality, there have been advances in [[air pollution control devices|air pollution reduction technology]] that have led to declines in emissions of different pollutants.<ref name="RE3">Clean Air Strategic Alliance.

Available: http://www.casadata.org/whatis/Index.asp</ref> The quality of the air we breathe depends on how quickly pollutants are emitted and how well the atmosphere can disperse these pollutants. This dispersion is controlled by the wind as well as [[weather]] and the [[temperature]].<ref name="RE3"/>
