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.
The ozone is depleted due to greenhouse gases. Pollution causes these greenhouse gases.
Ozone layer is depleted by the pollutants. CFC's are such man made pollutants which destroy the ozone.
Air pollution causes global warming. This global warming can thus cause ozone depletion.

Ozone layer is a layer of earth. It is being depleted. The reason is CFC.
Ozone layer is being depleted by CFC's. They react with ozone and decompose it.
Ozone is being depleted by CFC's. They react with ozone and deplete it.
The stratospheric ozone layer is being depleted by pollution from manmade chemicals. This ozone layer plays an important role in protecting life on earth from ultraviolet radiation given off by the sun.
See "What is causing the depletion of the ozone layer?"
The ozone layer gets depleted where temperature is cool. It is because of the property of ozone.
Ozone layer depleted. It is because of use of CFC's.
Ozone layer is depleted. The main cause are CFC's.
