Ozone - Good and Bad

Ozone has both good and bad effects. The ozone layer high in the stratosphere is beneficial because it prevents harmful ultraviolet radiation from reaching the earth's surface. This ozone is not harmful because it lies far higher in the atmosphere than the air we breathe. However, high concentrations of ozone at ground-level have harmful effects on human health, vegetation, and many materials used by humans.
