World Ozone Day 2022, Theme, History & Significance
World Ozone Day 2022: Every year World Ozone Day or the International Day for the preservation of the Ozone Layer is observed on the 16th of September. World Ozone Day is marked to create awareness among the people that the ozone layer is depleting gradually and we should take certain measures to preserve it. International Day for the preservation of the Ozone Layer signifies that Ozone Depletion is being caused due to the formation of Ozone Holes which are occurring because of Ozone Depleting Substances(ODS). Some of the Ozone Depleting Substances include chlorofluorocarbons (CFCs), HCFCs, and halons. The ozone layer is found in the earth’s stratosphere and protects the earth from the harmful rays of the sun by absorbing 97-99% of medium-frequency radiation. In this article, we have mentioned the History, Significance, and Theme of World Ozone Day 2022.
World Ozone Day 2022: History
The United Nations General Assembly proclaimed in 1994 that the 16th of September will be observed as World Ozone Day or International Day to preserve the Ozone Layer. On September 16, 1987, the “Montreal Protocol on Substances that Deplete the Ozone Layer” was signed by the Governments of 46 countries. To mark this particular event 16th September was chosen as the Day to observe World Ozone Day. For the first time, the International Day for the Preservation of Ozone Layer was marked on September 16, 1995.
World Ozone Day 2022: Significance
World Ozone Day is commemorated to highlight the significance of Ozone Layer and the necessity to preserve it from getting depleted. First time in 1970s the scientists found out that the ozone layer is getting depleted. In the polar regions around the north and south pole the ozone shield has become thin. The presence of Ozone Layer reduces the harmful UV radiation especially the radiation of UV-B variant from reaching the surface of the Earth. The Radiation is very harmful and is responsible for causing sunburn, skin cancer and cataracts among many other diseases. The ozone layer will get depleted at its minimum extent if we practice certain activities:
- Use Air Conditioners only when required and at regular time intervals have a proper maintenance of ACs.
- Use minimum vehicles and prefer sharing them because they release large amount of greenhouse gases that ultimately leads to ozone depletion.
- The cleaning products used in homes must be eco-friendly.
- Avoid the use of pesticides because they somehow get into the atmosphere and affect the ozone layer.
