Ozone Depletion

Ozone Depletion

• Caused mainly by emmissions of CFC's into the atmosphere.
• Main Sources of CFC's are
• Aresol can propellants
• Refrigerant gasses

• CFC's enter the atmosphere and destroy Ozone (O₃)

• Ozone blocks harmful Ultraviolet Light (UV) from entering the atmosphere.
• Over time this has caused ignificant "Ozone holes" over the polar regions of the earth, and these are becoming larger.

Scientists fear that increased UV levels could cause increases in cancer rates in affected areas.
