Pollution is not a ozone layer issue. The "hole" in the ozone layer is a thinning of the layer (mostly above the South Pole) that occurs each year for a short period (about 4 months total cycle) because the sun is unable to hit the layer. Ozone is a very unstable element and with energy from the sun it degrades into simple oxygen (O2). The layer is normally about 3 mm thick and once a year, when the sun can not hot the layer, it degrades to about 1 mm.

There is some trace amounts of a few items such as CFC's in this area. These gases do have the ability to react with ozone.
