  • Ozone Layer
    • CFCs
      • Odourless
      • Chemically stable
      • Non-flammable
      • Tastless
      • Why we use them
        • Refrigerant gases in...
          • Air Conditioners
          • Freezers
          • Refrigerators
      • CFCs
        • HCFCs
          • HFCs
    • UV radiation breaks CFCs down
      • Chlorine reacts with Ozone
        • Breaking it down into O2 and ClO
          • Cl + O3 --> ClO + O2
            • ClO + O --> Cl + O2
              • O3 + O --> 2O2
    • Sherry Rowland
      • Looked at CFCs in troposphere
      • Discovered that CFCs were destroying the Ozone Layer
    • Dr Joe Farman
      • Discovered the 'Hole' in the Ozone Layer over Antartica
    • Montreal Protocol
      • International meeting
      • Government agreement to cut out CFCs
      • Cut out HCFCs in developed countries by 2020
        • And then the rest of the World by 2040
