Chlorofluorocarbon (CFC) is a harmful gas because it destroys the ozone layer. It has largely been phased out now, but it remains in the atmosphere for many years and is very destructive. It takes almost seven years for it to rise and move up to the ozone layer where it releases chlorine. This chlorine destroys ozone and keeps reforming and destroying more.
