The primary culprit in the breakdown of Freon is the Flourine. Flourine reacts with almost anything. Here is an interesting fact, volcanoes put tons of Flourine compounds into the atmosphere when they erupt. When mount Pinutabo erupted in the Philippines, it put more Fluorine compounds into the atmosphere in its first few seconds than man had ever produced. The Pinutabo eruption lasted 38 minutes if I remember correctly.
The bottom line is that our mere presence on Earth is insignificant compared to what nature produces. Consequently, what we do as humans is pretty minor.
As a chemist, I am well aware of all this.
My first job task in my first new job after grad school involved hydrofluoric acid and silicon tetrafluoride (specifically developing instrumentation to measure both, which I succeeded in doing). An interesting assignment and real learning experience.
I am simply pointing out errors of fact in understanding about the ozone hole chemistry of certain fluorocarbons, which is, in fact, correct.
The overall impact of human vs other natural mechanisms is still subject to all the flaws of "model-based" alarmism.
