  • Chlorofluorocarbons are involved in a catalytic reaction CFCl3 + UV Light ==> CFCl2 + Cl Cl + O3 ==> ClO + O2 ClO + O ==> Cl + O2 Cl + O3 ==> ClO + O2 ClO + O ==> Cl + O2
  • Depletion of the ozone results in stunted plant growth, cataracts, and skin cancer.
  • The Montreal Protocol was created to lower the amount of ozone-destroying substances in the atmosphere.
