Depletion of the ozone in the stratosphere is known to cause what 6 things? 1.Crop losses 2.Increases in eye diseases 3.Skin Cancer 4.Reduced marine life 5.Deforestation 6.Increased ground level ozone What happens when CFC or HCFC molecules get in the stratosphere & free atoms of Chlorine are set free? These atoms attack Ozone Molecules causing the formation of Chlorine Monoxide (CLO), after colliding with another Ozone Molecule, causes 2 Oxygen (O2) molecules to be made & leaving an atom of chlorine to act as "Free Agent" starting the process over until 100,000 molecules of Ozone are destroyed by just one atom of chloride.
