What is causing the ozone layer to get thinner?
Ozone in the upper atmosphere constantly breaks down and forms again. But because of chemicals called CFCs (chlorofluorocarbons), the ozone layer is breaking down faster than it can replenish itself. One CFC molecule can destroy as many as 100,000 molecules of ozone. CFCs are made for use in refrigerators and air conditioners. Certain types of insulation and foam rubber also contain CFCs. Is there an ozone layer problem in Washington State? The problem is worldwide. People who work or play outdoors during the summer are at higher risk to exposure from UV light.
