The pollutant that is beleived to be causing damage is CFC. It is a synthetic chemical that might lead to ozone depletion.
The chlorine molecules that break from CFCs (chlorofluorocarbons) destroy the ozone molecules.
CFC's are the pollutants which are man made. They destroy ozone to form their own compounds.
CFC's are causing damage to ozone layer. They react with ozone to deplete it.
See "What is causing the depletion of the ozone layer?"
Ozone in the ozone layer is not at all a pollutant but it is something without which no ozone layer may have existed. Ozone can be considered as a pollutant in the stratospheric region but in the stratosphere or the ozone layer it is of full or complete use. No harms there.
burning fossil fuels
The ozone at ground is a secondary pollutant. It is also called bad ozone.
Ozone layer is a pollutant when it is in lower atmosphere because there it does not protect us. The stratospheric ozone is a good one.
Basically we are. Well, everyone is. Littering is causing troubles for the ozone layer and so are factories. So basically we all are.
CFC's are the group of pollutant gases. They break up the ozone layer.
Depleting the amazon will cause global warming, That will cause ozone depletion then.
CO2 emissions and Greenhouse gasses damage the Ozone layer. Causing global warming.
Ozone gets in your lungs as ground ozone. It is a pollutant.
