The International Day for the Preservation of the Ozone Layer, also known as 'World Ozone Day,' is observed annually on September 16th to commemorate the date when the nations signed the Montreal Protocol on Substances that Deplete the Ozone Layer. This commemoration was made in 1994 to mark the anniversary of the protocol's signing in 1987. The treaty will celebrate its 35th anniversary on this day to recognize its role in putting an end to one of humanity's greatest threats. Let us learn more about why oxygen trioxide is important in protecting humans from the sun's harmful ultraviolet rays.

International Day for the Preservation of Ozone Layer: History
Ozone, also known as trioxygen, is a colorless gas found in the Earth's stratosphere. This fragile gas shield protects the Earth from the sun's harmful rays, thereby preserving life on the planet. However, scientists discovered an extreme depletion of ozone over the Antarctic in 1985, calling the protection against harmful radiations into question. Further research established that the decrease in the Ozone layer was caused by the use of chemicals such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).
Thus, Following the signing of the Vienna Convention for the Protection of the Ozone Layer by the 28 nations in March 1985, The Montreal Protocol on Substances that Deplete the Ozone Layer was drafted in September 1987. By which, the international community regulated CFC production and consumption to protect the Ozone layer.
Although the Treaty prohibited the consumption and production of harmful substances such as CFCs that cause Ozone Layer depletion, long-lived chemicals in the atmosphere continue to affect the ozone layer. However, the trend in ozone layer depletion has been sufficiently reduced in the last 30 years, and it is expected that the Ozone layer hole over Antarctica will be recovered to pre-1980 levels by 2070.
Where you would like to hear that the Montreal Protocol implementation progressed well in both developed and developing countries, resulting in the rescue of human civilization from one of the greatest threats of all time.
International Day for the Preservation of Ozone Layer: Significance
The day is significant in raising awareness about Ozone Layer depletion and the importance of the Ozone Layer in preserving life on Earth, among individuals and policymakers.
As previously stated, the Ozone layer present in the stratosphere (15-35km above Earth) protects our planet from harmful UV rays, which can have negative effects on the human population and life on the planet. Depletion of the Ozone layer could lead to diseases such as cancer, snow blindness, skin aging, cataract, and other afflictions. Because harmful UV rays can significantly disrupt life on Earth, it is critical to regulate the use of chemicals and substances affecting the planet earth.
It was discovered that chlorofluorocarbons (CFC) are the main chemicals that significantly contribute to the depletion of the Ozone layer, which was previously primarily used as a refrigerant, but today the CFC has been replaced with hydrochlorofluorocarbons (HCFC), which is found to be a week Ozone depleting substance but has a nearly linear impact on stratospheric temperature and ozone change. (HCFC) is now widely used in refrigerators as well as home and car air conditioners.

International Day for the Preservation of Ozone Layer 2022: Theme
The theme of 'International Day for the Preservation of Ozone Layer' or 'World Ozone Day' in 2022 is "Montreal Protocol@35: global cooperation protecting life on earth."
The theme acknowledges the role played by the Montreal Protocol in causing climate change as well as the necessity of working together, forming alliances, and fostering international cooperation to address climate challenges and safeguard life on Earth for future generations.
The importance of all nations cooperating in preserving the global environment and ensuring a better future for the next generation is highlighted by this year's International Day of Preserving the Ozone Layer theme.
International Day for the Preservation of Ozone Layer 2022: Activities
You can perform multiple activites to be a part of this International Event, where some of the activities are listed below.
1. Read the Background: The fight to review the Ozone layer is still ongoing, but we have made significant progress in stopping the thinning of the Ozone layer, with scientists expecting it to recover to pre-1980 levels around the year 2070.
2. Raise awareness about the day: You can raise awareness about the day by spreading the word about it on social media platforms and encouraging others to participate in the global event.
3. Report on the impending environmental threat: Not only is the Ozone Layer under threat, but there are also other, more connected environmental threats, such as climate change, clean water, ocean health, and biodiversity.
