Ozone is O3. It is created in the atmosphere when ultraviolet light reacts with oxygen molecules. This electrically charges them into o2

O2 + ( ultraviolet radiation 240 nm) → 2 O.

Oxygen doesn’t like being together with another oxygen atom and needs to be paired with something. This continues to become o3 in this process O + O2 → O3

O3 is also made by ionic breezes. It makes air crispy. This also explains why the air after thunderstorms is also crispy since the charged lightning bolt electrifies oxygen.

Ozone can be destroyed by a number of catalysts. Some of these are the hydroxyl radical (OH·), the nitric oxide radical (NO·) chlorine (Cl·) and bromine (Br·). All of these can come from natural or man made sources.

NOW

R12 is a CFC. CFC stands for Chlorofluorocarbon. A CFC is a relativly stable compound, however like oxygen when a CFC is struck by UV light the compoud breaks down into carbon, flourine, chlorine, and bromine.

POP QUIZ: What two elements of a CFC are also reactive to Ozone?
That’s right! Chlorine and bromine!

Now due to Earth’s atmophere being a constantly moving body of air. Chlorine and bromine eventually make there way up into the ozone layer by means of conduction (hot air rising). Although Chlorine and Bromine are in fact heavier then Oxygen they are spread gratly apart since they are in smaller quantities of oxygen. Think of it as a rock on a blanket spread out and people holding each end. Although the rock is pretty heavy, when every one pushes up on the rock it will give it enough momentum to go up.

The chlorine and bromine atoms then react with the O3 in a handful of reactions. One particular reaction is this:

Cl + O3 → ClO + O2

Oh no! The chlorine isn’t done with its devilish act yet! The ClO molecules continue their reign of terror on the ozone molecules:

ClO + O3 → Cl + 2 O2

Yarg!! It appears that r12 is not a great thing after all. This amongst other things has been steadly increasing those "made up" ozone holes

I hope this explanation helps. This has been researched and peer reviewed multiple times by many PhDs in many universities. Heck scientists have received Nobel prizes for this. There weren’t any politicians with the r134 lobby on this one.

Edit: R12 is also better than r134a.

Thank You, that is the best actual explanation anyone has ever presented me with.

I have one question though, the last reaction showed yielded one Cl and two O molecules. Would those two O molecules then tend to unite with another and form more O3 like you explained at the beginning? Since we know among other things the ionization from lightning helps in the production of O3, are you saying that our use of CFC's depletes the O3 faster than it can be naturally created?
