Ever calculated the molecular weight of a CFC molecule? It's a lot heavier than N2/O2 mixture of our atmosphere. How does something that heavy, coming out of our spray cans and air conditioner at sea level, rise up to above the stratosphere?
air currents (winds) mix the CFCs up into the atmosphere a good deal faster than CFC's molecular weight sinks it down.
