Where can I find chloroflurocarbon

Chlorofluorocarbons (CFCs) are the chemicals that are used in industry, refrigeration, air conditioning systems, and consumer products. Whenever CFCs are released into the air, they reduce the stratospheric ozone layer. The stratospheric ozone layer protects Earth’s surface from the harmful rays of the sun.

So nearest home for CFCs is your own your refrigerator and air condition system.

Open your refrigerator or your AC...
better if you can fly go up to ozone layer near Australia.
