They react with ozone. Decompose it and cause ozone depletion.
The chemical mainly responsible for ozone deplation are CFC's. They contain chlorine and fluorine which react with ozone to destroy it.
Chlorofluorocarbons (CFCs) are the main chemicals responsible for ozone layer depletion. Once released into the atmosphere, CFCs can reach the stratosphere where their chlorine atoms can destroy ozone molecules.
Chlorofluorocarbons (CFCs), halons, and certain types of hydrochlorofluorocarbons (HCFCs) are human-made chemicals that cause ozone depletion. When these substances are released into the atmosphere, they break down and release chlorine and bromine atoms, which then destroy ozone molecules in the stratosphere.
The compounds with the highest ozone depletion potential (ODP) are chlorofluorocarbons (CFCs), specifically CFC-11 and CFC-12, along with halons. These substances are long-lived in the atmosphere and are able to destroy ozone molecules efficiently.
The humans destroy ozone by usng CFCs. These are compounds which react with ozone to deplete it.
The chemical mainly responsible for ozone deplation are CFC's. They contain chlorine and fluorine which react with ozone to destroy it.

CFC's react with ozone to cause depletion. they decompose the ozone layer.
CFCs (chlorofluorocarbons) destroy ozone in the ozone layer.

As the CFCs are carried to Antarctica there is a big ozone hole. Chlorine and bromine atoms from CFCs (chlorofluorocarbons) separate and destroy ozone molecules, but remain active for several years continuing their destruction. So if more CFCs will be produced in the world more CFCs will be carried to Antarctica by the polar winds and more depletion and the rate of depletion will exceed the rate of formation of ozone molecules resulting in the expansion of ozone hole over Antarctica.
No, ozone depletion was caused by CFCs in the atmosphere.

CFC's are compounds which cause ozone depletion. They decompose ozone.
Manmade chemicals like chlorofluorocarbons and bromofluorocarbons are the major depleters of the ozone layer. The chlorine and bromine separate from the CFCs (chlorofluorocarbons) and destroy the ozone molecules.
