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.
