Ozone is good for biological systems, but only when it is not in close contact with them.
In the upper atmosphere (the stratosphere), ozone provides a shield that protects Earth from harmful ultraviolet radiation. When in contact with organisms in the lower atmosphere (the troposphere), however, ozone can harm them. Detrimental changes in ozone concentrations have occurred in both the stratosphere (losses) and the troposphere (increases) as a result of anthropogenic emissions of air pollutants.
