World Ozone Day Festival Images

World Ozone Day is observed on September 16 every year to spread awareness among people about the depletion of Ozone Layer and find possible solutions to preserve it. On this day, people from all over the world hold talks and seminars on the ozone layer. Educators teach students about the benefits of the Ozone layer and special events and activities are organised to spread awareness.

World Ozone Day 2022 Theme

"Montreal Protocol@35: global cooperation protecting life on earth" is the theme of World Ozone Day 2022.

World Ozone Day History

It was in 1994 when the UN General Assembly declared 16 September as the International Day for the Preservation of the Ozone Layer OR World Ozone Day.

As mentioned earlier, the date commemorates the signing of the 'Montreal Protocol on Substances that Deplete the Ozone Layer which was signed on 16 September 1987.

World Ozone Day Significance

What is the Ozone Layer?

Ozone, chemically represented as O₃, is made up of three atoms of oxygen. Ozone is a pale blue, harmful to life, smelly, and highly reactive gas present high up in the stratosphere. It is this high-up location of ozone that makes it beneficial for us rather than harmful. Had it been present closer to the earth's atmosphere, its greenhouse effect would be harmful to us leading to global warming and other disasters associated with it.

Where it is found?

It is found some 15-35 km above the surface of the Earth. It occurs naturally as well as a man-made product in the Stratosphere (Earth's upper atmosphere) and Troposphere (Earth's lower atmosphere.)

How Ozone Layer protects us?

Ozone reduces the harmful UV radiation, especially the UV-B variant, from reaching the Earth's surface and causing us sunburn, skin cancer and cataracts among many other diseases.

What if there is no ozone layer? If this invisible shield is somehow taken away, be ready for immune system impairment for life on land, and phytoplankton productivity interference for ocean life.

Cause of Ozone depletion The main cause of ozone depletion and subsequently the creation of an ozone hole is ODS (ozone-depleting substances). ODS are manufactured chemicals like halocarbon refrigerants, solvents, propellants, and foam-blowing agents. A few examples of ODS are chlorofluorocarbons (CFCs), HCFCs, and halons.
