CFCs were produced to be refrigerants and propellants. They served a need of modern society. They were relatively cheap and easy to form. No one knew they damaged the ozone layer (to whatever extent they do). They know to check now. 3rd world countries still produce them, because they are still relatively cheap and easy to form.
No.
The ozone hole is a natural, repeating occurance. CFCs may contribute to it containing less ozone, be larger, and last longer, but they are not responsible for the hole. Nature is.
The ozone hole can be repaired by curbing the use of CFCs. If there are no man made ozone destroying substances, the ozone layer will replenish itself.
The hole in the ozone layer came about because of the artificially produced gases CFCs (chlorofluorocarbons). These contained chlorine and bromine which destroyed ozone. CFCs are now banned. The ozone hole has very little to do with global warming.
In order to decrease the impact of ozone depletion, we should curb the use of CFCs. It is because in the absence of these CFCs, the ozone hole will automatically replenish.

CFCs
The thinning of ozone layer is called as ozone hole. CFC's are the ones that create the ozone hole.
Humans are causing the hole in ozone layer by using CFCs. These CFC are the factors responsible for depletion of ozone.

CFCs, or chlorofluorocarbons.

CFC's are man made chemicals. These react with ozone to deplete it.

polution and litter
Stratospheric pollution means depletion of ozone layer (ozone hole) by certain compounds like CFCs, oxides of nitrogen .

The ozone layer is a layer of ozone gas in the Earth's atmosphere that acts as a protective shield against harmful UV rays from the sun. The ozone hole, on the other hand, refers to a region in the ozone layer where the concentration of ozone is significantly depleted. This is primarily caused by human-made substances such as chlorofluorocarbons (CFCs) that break down ozone molecules. The ozone hole is a localized area within the larger ozone layer where ozone depletion is most severe.
