The United Nations’ International Day for the Preservation of the Ozone Layer is celebrated on the 16th September every year. Commemorating the 1987 signing of the Montreal Protocol on Substances that Deplete the Ozone Layer, the day advocates activities that create awareness on topics related to climate change and ozone depletion.
Not so long ago, humanity stood on the brink of a self-inflicted catastrophe. Our use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation.
