It is amazing what the human race is capable of globally when they work together. The International day for the preservation of the ozone layer is in commemoration of the Montreal Protocol, a treaty signed on 16th September 1987. A global treaty designed to phase out the production of ozone depleting chemicals like CFC’s {chloro fluoro carbons}. Since 1987 global emissions of ozone-depleting substances have declined by more than 99%. The Antarctic ozone hole slowly started decreasing after this agreement was signed and in December 2020 closed according to the World Meteorological Organization: https://public.wmo.int/en/media/news/record-breaking-2020-ozone-hole-closes
What more can we do to protect the ozone layer?
1} Buy air-conditioning and refrigeration equipment that do not use HCFC’s as refrigerant.
2} Minimize the use of cleaning products and pesticides that are harmful to the environment.
3} Buy peat free compost or make your own compost.
All these efforts will also help toward reducing climate change which is the global challenge today.
