The levels of stratospheric ozone are very important and a thinning ozone layer can cause problems. The thinning of naturally occurring ozone at the poles (commonly known as the "ozone hole") is due to [[photochemical reaction]]s with [[chemical]]s such as chlorofluorocarbons. A reduction in stratospheric ozone leads to increased levels of UV-B radiation at the ground, which can lead to increased risks of skin cancer. Recovering levels of ozone in the upper atmosphere (repairing the hole in the ozone layer) is a good thing, which is the opposite of increasing the levels of ozone in the lower atmosphere.<ref name=atm/></ins></div></td></tr>

Tropospheric ozone is considered an [[air pollutant]] as it causes respiratory effects in humans and impairs plant growth. Ozone in the lower atmosphere is mostly produced by photochemical reactions involving [[volatile organic compound]]s and [[nitrous oxide|oxides of nitrogen]]. These compounds have natural sources like vegetation, wildfires, and lightning, and [[anthropogenic]] sources such as [[fossil fuel]] combustion and human-caused [[biomass]] burning. Tropospheric ozone is also an important [[greenhouse gas]] contributing to [[global warming]].<ref name=atm/> For more information about ozone in the lower atmosphere, visit the page on [[ground level ozone]].</ins></div></td></tr>
