CFCs
Chlorofluorocarbons (CFCs) deplete the ozone layer because when they are released into the atmosphere, they break down and release chlorine atoms. These chlorine atoms then react with ozone molecules in the stratosphere, causing the ozone molecules to break apart, leading to ozone depletion.
The hole in the ozone layer is primarily caused by human activities releasing chemicals called chlorofluorocarbons (CFCs) into the atmosphere. These CFCs break down ozone molecules, leading to the thinning of the ozone layer.
Chlorofluorocarbons (CFCs) are primarily responsible for the reduction of ozone content in the atmosphere. When released into the atmosphere, CFCs break down ozone molecules in the stratosphere, leading to the thinning of the ozone layer.
Chlorofluorocarbons (CFCs) are chemicals that react with and cause the destruction of stratospheric ozone. When released into the atmosphere, CFCs break down and release chlorine atoms, which then catalyze the breakdown of ozone molecules. This depletion of ozone leads to the formation of the ozone hole in the stratosphere.

Chemicals such as chlorofluorocarbons (CFCs) and other ozone-depleting substances released into the atmosphere can break down ozone molecules in the stratosphere. These chemicals react with ozone, causing it to break apart and reduce the overall levels of ozone in that layer of the atmosphere.
Chlorofluorocarbons (CFCs) are the main cause of ozone layer depletion. When released into the atmosphere, CFCs break down ozone molecules, which leads to a thinning of the ozone layer and increased exposure to harmful ultraviolet radiation from the sun.

The production of CFCs in Canada has contributed to ozone layer depletion globally, not just in Canada. CFCs break down ozone molecules in the stratosphere, leading to the formation of the ozone hole. Canada's efforts to phase out CFCs through international agreements like the Montreal Protocol have helped mitigate the damage to the ozone layer.
CFCs only interacts with stratospheric ozone because the ultraviolet light is much stronger at that altitude. UV breaks down the CFCs to release ionic chlorine (and bromine from Halons) which react with ozone to produce oxygen and atomic oxygen. Ozone does not directly interact with these compounds. It takes energetic light to "deplete ozone" with these compounds. Water vapor does a good job...
