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

2 Ozone Importance OZONE SHIELD PROTECTS EARTH FROM ULTRAVIOLET
RADIATION

3 Ozone Importance ULTRAVIOLET RADIATION FROM SUN OZONE = SUNSCREEN

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

5 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

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