Cfcs were gases used in hair spray, refrigerators, and insulating foams the ozone layer is a layer of atmosphere located between 6 and 25. Decline of cfc-11 has slowed in recent years, pointing to a that keeps the hole in the ozone layer on track to shrink over the coming. Cfcs chlorofluorocarbon (cfc) is an organic compound that contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane and ethane. When the ozone hole was discovered, it became a worldwide sensation in 1974, a landmark paper showed that chlorofluorocarbons (cfcs).

If production continues, it could undermine our ozone layer's fragile recovery. An especially important cause of destruction of the ozone layer is a group of chemicals called chlorofluorocarbons or cfcs developed in the 1930s, cfcs are. In the early 1980s, scientists began accumulating evidence that the ozone layer was being depleted due to an overabundance of cfcs in the atmosphere cfcs . The harmful chemical, dubbed trichlorofluoromethane (cfc-11), has been banned for decades in an effort to save the ozone layer however, a. However, the stunning discovery of the antarctic ozone hole in 1985 proved the skeptics wrong human-generated cfcs were indeed destroying earth's.
