CFC's are the chemicals. They react with ozone to deplete it.
See "What are the causes and effects of ozone layer depletion?"
Chemical
The ozone depletion is increasing the amount of UV radiation that reaches the earth....
Ozone layer and it's depletion is pure chemistry. It's formation and depletion is due to the chemical bonds.
The chemical compound responsible for the depletion of the ozone layer is chlorofluorocarbons (CFCs) and other halocarbons. These compounds contain chlorine and bromine atoms that can break down ozone molecules in the stratosphere.
Ozone layer has undergone various changes. These are the depletion of ozone molecules.
The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.The ozone depletion is the thinning of ozone layer. It is most prominent over Antarctica.

damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
The phenomenon of fading away of ozone layer is called as ozone depletion. It is due to various ozone depletion substances.
The depletion layer in a diode is thin because it forms due to the diffusion of charge carriers (electrons and holes) from the P-type and N-type regions. As charges diffuse, they create a region depleted of majority carriers, leading to the formation of the depletion layer. The thinness of the depletion layer allows for efficient blocking of current flow when the diode is in reverse bias.
on forward biasing width of the depletion layer decreases whereas on reverse biasing the width of depletion layer increases.
