They were made and used because they are extremely stable, they had useful gas-to-liquid transition temperatures, and they were cheap (fluorine production is dirty, dangerous, and hence expensive).
They contribute to ozone depletion because they are so stable they can only be brokne down in the intense radiation of the ozone layer, and their chlorine payload is released to do its dirty deed over and over.
The CFC's are responsible for ozone depletion. They come from refrigerants.
Volcano and Oceans do contribute to ozone depletion. But the extent to which they do is very less.
CFc's and freons are responsible. They cause the depletion of ozone layer. The depletion is due to Chlorine and Fluorine.
The various CFC's and the H CFC's are the ones which contribute maximum to the ozone depletion.
You can contribute from home towards ozone depletion. You can plant trees and stop use of CFC's.
Refrigerants release CFC's. They react with ozone to deplete it.
Human can help prevent ozone layer depletion. They can stop using CFC gases like refrigerants and contribute for better tomorrow.

CFc's and freons are responsible. They cause the depletion of ozone layer. The depletion is due to Chlorine and Fluorine.
The various CFC's and the H CFC's are the ones which contribute maximum to the ozone depletion.
Ozone depletion can be stopped by substitutuing refrigerants with some other gases. It will help stop Global Warming too.
Ozone depletion is due to CFC's. These CFC's are released from refrigerators.
You can contribute from home towards ozone depletion. You can plant trees and stop use of CFC's.
The depletion of ozone in stratosphere is due to the continues usage of CFCs. These cfc contribute to the depletion of ozone molecules.
The use of CFC contributed to depletion of ozone. It is because they react with ozone to decompose it.
Depletion of ozone alters ecosystem. This then alters the climate change.
