(Fisher 25). This means the chlorine molecule can stay in the atmosphere, and it has been proven that a single chlorine molecule can destroy up to one hundred thousand molecules of ozone (Dolan 28). What Can We Do?Scientists have discovered that the ozone layer can recover from the damage cause to it. If all CFCs were to be banned completely as of now, the earliest date the layer could recover is 2050 (Environment Canada). Since many ODSs have been banned, the hole in the ozone layer has stopped growing, however it hasnt gotten any smaller. Aerosol cans, fire extinguishers and insulating products such as foam, are all currently CFC free (Gribbon 57). There is now the major task of finding an alternative coolant for use in refrigerators and air conditioners. Chemical companies have been looking for other gases to use in these products but are yet to fined a suitable substitute. ConclusionTo allow the ozone layer to recover, humans must stop all CFC emissions. Air conditioners which still use them must be banned, and production must be stopped. In doing this we will be allowing the ozone layer a chance to heal itself and to keep on protecting the Earth. We should stop the effects of these chemicals while we still can, before the Sun permanently damages the quality of life on our planet....
