September 16 every year is dedicated to a cause that might not be visibly relevant but is the most important in today’s day and age. After a deal called Montreal Protocol on Substances that deplete the ozone layer signed by almost every country in 1987, the UN General Assembly, in 1994, proclaimed this day as the International Day for the Prevention of the Ozone Layer.

This year’s theme for the International Day for the Prevention of the Ozone Layer is ‘Montreal Protocol – Keeping us, our food, and vaccines cool.’ The theme is selected for the year 2021 to highlight the long-term results of the 35-year-old protocol, the first ever to be ratified by all the 197 members of the United Nations.
