This is probably the most retarded thing I have seen lately. It was defeated by REGULATION and now is not much of a problem. The ozone layer hole would be a good example of why we should ban things to help stop climate change.
From the NIH:
Chlorofluorocarbons (CFCs) are a group of odorless manufactured chemicals. Because they damage the earth’s ozone layer, CFCs have been banned since 1996. Before CFCs were banned, they were used in aerosols, refrigerators, air conditioners, foam food packaging, and fire extinguishers.
