1 Our Disappearing Ozone

2 UV Radiation Causes skin cancer, cataracts, weakened immune system Creates smaller crop yields Damages fish Changes biogeochemical cycles

3 What Is The Ozone Layer?

4 Upper Ozone Chlorofluorocarbons (CFCs) Methyl bromide Halons Methyl chloroform

5 Ozone Hole Appears each spring in Antarctica Results from an abnormally thin ozone layer Discovered in 1980s

6 Creation Of An Ozone Hole

7 Ozone Action Days Conserve electricity Carpool Don’t use gas- powered equipment Refuel after dusk Limit engine idling
