OZONE :) =]XD rofl ^V<>-}

Ozone is a form of oxygen, o3. In the upper atmosphere, it absorbs ultraviolet rays, thereby preventing them from reaching the surface of the earth. In the lower atmosphere it is a pollutant. Ozone is being depleted by a human produced chemical called CFCs witch contain chlorine, fluorine, and carbon atoms that are bound together. This tears apart the ozone and turns it into oxygen. There is a giant ozone hole right over Antarctica. SAVE TH O3!!!!
