Life depletes when Ozone Depletes. We know that life would not be possible without the Sun. But keeping into consideration the amount of energy emanating from the Sun, it would be too much for life on earth to be sustained if it were not for the Ozone layer. Sun emits harmful ultraviolet radiation and the Ozone layer acts as a protective stratospheric shield, hence making our life as we know it possible.
Today, i.e 16th September is observed as International Day for the Preservation of the Ozone Layer or World Ozone Day. In order to keep in check on substances that deplete the Ozone layer, a deal named Montreal Protocol was signed by almost every country in the year 1987 and subsequently, in 1994, the UN General Assembly proclaimed this day as the World Ozone Day.
The history of the day to preserve the future:
The blue planet is blessed with natural substances that have kept life on this planet intact. For years now, humans have made their contribution to bringing the planet in peril and one of the examples is harming the environment as a consequence of depletion of the stratospheric layer of gas that safeguards people on earth from harmful cosmic rays.
To take actions against this, and to curb the existence of all the substances that add to the ozone depletion, Montreal Protocol came into existence where countries from across the globe decided to curb substances such as:
These substances are widely used for cooling and refrigerating purposes. As a result of the usage of these harmful substances, a hole in the ozone layers in Antarctica was discovered back in 1970, which ultimately led to acute global warming in the past 20 years. Although the 1985 convention that gave rise to the Montreal deal did make progress in conserving the Ozone layer and further in January 2021, the Antarctic hole caused by Ozone-depletion was finally closed as a result of the collaborative efforts by these countries, according to the World Meteorological Organization.
Ultimately, the main aim of the Montreal deal was to control, preserve and take timely measures towards curbing the consumption of substances that cause the depletion of the ozone layer.
The theme for 2021:
The theme for 2021 for International Day for the Preservation of the Ozone Layer is ‘Montreal Protocol -‘Keeping us, our food and vaccines cool.’ According to the official website of the UN, this year’s Ozone Day seeks to highlight the Montreal Protocol that does so much more, including, slowing climate change and helping to boost energy efficiency in the cooling sector, which contributes to food security.
