Ozone layer depletion has scared several people over the years, but now there is hope for a recovery. The ozone layer has been severly depleted right above the artic areas, which gives scientist a new suspect to blame. Instead of pointing their fingers at greenhouse gases, they have realized that climate has a major role on ozone depletion. The colder it is the more chlorine reactions occur, and the easier the ozone will deplete. Several people were scared that radiation would spill into earth drastically and cause a higher rate of cancer, but the amount of radiation absorbed by the earth is not enough to cause any increase in cancer. Now, scientist beleive that the ozone layer will recover by the end of the century as long as we prevent using chlorofluorocarbons (CFC’s).
