16 September was declared as International Day for the Preservation of Ozone Layer by the United Nations General Assembly. The designation was made on 19 December 2000 which commemorate 1987 date on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed. World Ozone Day shows that the only way to solve major global problems is through collective decisions and science-led action.
30 years after the signing of the protocol, the breach in the ozone layer was closed. Considering the nature of the ozone depletion gases, their chemical effects are predicted to last between 50 and 100 years.
The ozone layer or also known as the ozone shield, a porous layer of gas, absorbs most ultraviolet rays in the earth’s stratosphere. These rays can cause many diseases of the skin.
The United Nations and 45 other countries signed the Montreal Protocol on Ozone-depleting substances on 16 September 1987. This day is observed every year as International Day for the Preservation of Ozone Layer. The aim of the Montreal Protocol is to protect the ozone layer by reducing the production of ozone layer depletions.
Ozone for Life
This year International Day for the preservation of the Ozone layer will focus on Ozone for life and will celebrate 35 years of ozone layer protection. This year, we mark 35 years of the Vienna Convention and 35 years of worldwide conservation of ozone layers. Without sunlight, life on Earth will not be possible. Yet radiation from the sun would be too much to survive if it were not for the ozone layer for life on Earth. This stratospheric layer protects the earth from the harmful ultraviolet radiation of most of the sun. Sunlight allows life, but the layer of ozone allows life as we know it.
