It was in the 1970s that scientists first discovered the harmful effects of chlorofluorocarbons (CFCs) on the ozone layer. This prompted an international effort by countries around the world to work together in resolving this issue.
As part of the Montreal Protocol, signed on September 16, 1987, some industrialized countries agreed to reduce CFC production by using substitutes such as hydrochlorofluorocarbons (HCFCs) and ozone-friendly products. Such substances are not as harmful as CFCs, although they can potentially deplete ozone levels. With continued efforts, replenishing the ozone layer seems a real possibility. Scientists predict that by 2049, ozone levels will see resurgence back to 1970 levels.
