Ozone Importance GOOD: Stratosphere Ozone = O3 BAD: Ground (SMOG)

Ozone Importance OZONE SHIELD PROTECTS EARTH FROM ULTRAVIOLET RADIATION

Ozone Importance ULTRAVIOLET RADIATION FROM SUN OZONE = SUNSCREEN

ULTRAVIOLET RADIATION UV destroys phytoplankton UV causes skin cancer / sunburn UV causes eye damage UV mutates amphibians and kills eggs

OZONE PROBLEMS CFC’s = chlorofluorocarbons destroy ozone CFC’s found in coolants/aerosols/foams Takes 50 years to replace ozone Ozone Hole at the poles

What have we done? Montreal Protocol Countries agreed to stop using CFC’s
