World Ozone Day - September 16

The ozone layer located within the stratosphere of the earth receives majority of UV rays from the Sun. It has a greater amount of ozone than other parts of the atmosphere, but being comparatively tiny in proportion to other gases in the stratosphere. With location and season fluctuations, it typically occurs between 10 and 22 miles above the earth's surface in the lower stratosphere.

The ozone layer was found by French physicists Charles Fabry and Henri Buisson in 1913. There was no radiation below a wavelength of about 310 nanometers at the ultraviolet end of the spectrum, despite measurements of the sun's radiation revealing that it typically matches a spectrum of a black body with extremely high temperatures. This prompted the researchers to conclude that the UV radiation that was absent was being absorbed by the atmosphere. After conducting numerous scientific investigations, it was eventually determined that the spectrum of the missing radiation could only be matched to ozone, one known molecule.

Every year, we celebrate the International Day for the Preservation of the Ozone, also known as World Ozone Day, on September 16. This date was specifically selected by the United Nations General Assembly in 1994 to commemorate the historic signing of the Montreal Protocol on Substances that Deplete the Ozone Layer by numerous countries on the same day in 1987. This protocol marked the initiation of a vital initiative to safeguard the ozone layer, addressing the urgent need as it began to deplete.

Fast forward 30 years from the establishment of the Montreal Protocol, and we have witnessed a promising development: the ozone hole has been found to be gradually closing. The positive impacts of these efforts are expected to endure for as long as a century.

World Ozone Day Concept

The Montreal Protocol's beneficial effects on ozone layer recovery and mitigating climate change, particularly through the Kigali Amendment, which gradually phased out hydrofluorocarbons (HFCs), a class of potent greenhouse gases, are the focus of this year's subject.

The Kigali Amendment's full and universal acceptance would prevent up to 0.5 degrees Celsius of warming by the year 2100. These gains may quadruple if energy efficiency measures are implemented concurrently with the phase-out of HFCs.

The earth is getting warmer. The need for cooling is increasing along with the rise in average temperatures. The consumption and emission of HFCs might rise as a result of this.

A crucial instrument for reducing global warming is the universal passage and implementation of the Amendment, which will gradually phase out HFCs from cooling systems and make them more environmentally friendly.

We are inviting all parties to participate in World Ozone Day celebrations and use the materials produced to educate the public on the vital work being done by the Montreal Protocol to protect both us and the environment. The concept is represented in the posters.

World Ozone Day History

The International Day for the Preservation of the Ozone Layer was established by the United Nations General Assembly (UNGA) in 1994. However, the Montreal Protocol was ratified in 187, and efforts to give the agreement an official seal of significance were launched in 1995 with relation to the same. All 197 UN members have accepted this convention, which prohibits the use of substances that deplete the ozone layer. Now 16th September day is special each year.

The Montreal Protocol aims to preserve the Ozone layer by limiting the production of substances thought to be contributing to its thinning.

World Ozone Day Celebration Activities 

On the International Day for the Preservation of the Ozone Layer, several events are held all around the world to increase awareness, advance peace, and motivate people to take action in favor of a more tranquil and harmonious world. Perform these activities to understand the importance of Ozone Day. Some examples of typical activities for Ozone Day celebration are listed below:

• Create artwork, articles, plays, or paintings that explore the idea of a world without the ozone layer.

• Create logos for products that are ozone- and CFC-friendly.

• Send newspaper stories on the ozone problem or write an ozone world day essay to your community.

• Create a display of CFC-using products, such as spray cans, foam pillows, Styrofoam cups, images of air conditioners and refrigerators, etc., along with some potential CFC-free alternatives, including cotton pillows and earthen or steel cups.

• Use newspaper clippings, advertising, and their own essays and captions to create a wall paper exhibit on the topic. The exhibit might be placed where it could be seen by everyone in the school.

• Have a contest to see who can create the most words out of the phrase "chlorofluorocarbons destroy ozone."

• Write to manufacturers of air conditioners and refrigerators to inquire about their phase-out plans.

• Invite a refrigerator engineer to speak to the class on the usage of CFCs in their products, including any substitutes that may have been made.

• Make a commitment to protect the ozone layer.

Conclusion:

World Ozone Day 2023 will be celebrated for September 16 and is also known as the International Day for the Protection of the Ozone Layer. The goal of the day is to raise public awareness of the need of safeguarding the ozone layer.

By altering plant life cycles and upsetting the food chain, ozone depletion has a negative impact on the environment. It is in charge of altering atmospheric patterns. Plankton-dependent animals won't be able to survive if microscopic organisms like them struggle to thrive.
