CFC's i.e. Chlorofluorocarbons are the chlorine and fluorine containing compounds which are present in refrigerators, deodorants, aerosol cans etc. These compounds when reach the atmosphere or the ozone layer react with the ozone to form unstable compounds mainly chlorine monoxide. This chlorine monoxide further reacts with the ozone to form oxygen back and chlorine is further produced. this chain continues and the process of depletion of ozone layer becomes a continues phenomenon thus leading t the so called ozone hole.
CFC's we know harm the atmosphere. But they were not known to do this when produced.
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
CFC's react with ozone. They decompose it.
They are depleting ozone layer , increasing UV light which is cause of cancer , global warming etc .
they create holes in the atmosphere
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
humans use products containing CFCs which accumulate in the atmosphere.
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
Satellite measurements of light passing through the atmosphere
CFC's when mix with ozone react with it. they thus deplete the ozone in atmosphere.

CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.
ozone
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
By the CFCs being sorced into the air, the sun is Breaking them down into the earth.
humans use products containing CFCs which accumulate in the atmosphere.
carbon dioxide

They don't. CFCs (chlorofluorocarbons) are non-toxic to humans and animals. They only kill ozone molecules.
They are carried by westerlies. They destroy the ozone.
