The theory of CFC reaching and destroying the ozone layer located high in the atmosphere is just that, an unproven theory. Somehow, CFC molecules weighing four to eight times as much as air molecules are supposed to find their way aloft to the ozone layer. In reality, most CFC escaping into the atmosphere falls to the surface of the earth, where bacteria that consume naturally produced CFCs, decompose them within a few days or few weeks.
