Discovered in 1913 by French physicists Charles Fabry and Henri Buisson, the ozone layer or ozone shield is a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet radiation, as defined by Wikipedia. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometres (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically. It is the preservation of this Ozone layer that brought into existence the World Ozone Day.
Every year, 16th September is celebrated as International Day for the Preservation of the Ozone Layer across the globe. 32 years ago, on 26th August 1987, 197 countries signed the Montreal Protocol to prevent the use of substances that negatively impact the ozone layer. The treaty was recently amended as well. “The Montreal Protocol on Substances that Deplete the Ozone Layer” was enforced on 16 September 1989 by the United Nations and has shown positive effects year after year. So much so that, it is considered the most successful international environmental treaty to date.
’32 Years and healing’ is the aptly dedicated theme for this year. It showcases hope and progress towards making amends to keep the Ozone layer and thus the existence of Earth safe and sound.
Here’s how Twitter is celebrating World Ozone Day:
This #WorldOzoneDay, let's switch to public transport. A train carries many commuters at the same time without much pollution, while private vehicles cause more pollution. So, let's spread awareness about the importance of trains and together let's reduce pollution. pic.twitter.com/6yGJZ2Ghjv

Did you know that the ozone layer is healing?
In the 1980s, it was confirmed that man-made chemicals were severely damaging the Earth's ozone layer, the precious gas shield around the world that protects us from the Sun. #WorldOzoneDay pic.twitter.com/SfbJ7ZpPqn

Ozone is like immune system to any form of life, giving protection against harmful and lethal solar flux. Do the needful to protect our ozone. Get your vehicles' pollution level checked duly. #WorldOzoneDay

On International #OzoneDay we celebrate an environmental success story. Thanks to #MontrealProtocol the ozone layer is expected to recover. WMO's Global Atmosphere Watch network measures ozone to support policy and inform #ClimateAction. pic.twitter.com/WU5DHUATUz

The Earth without the ozone, is a house without a roof.?
Let's us each take a step, to reduce our carbon footprints and save the Ozone Layer from depletion.#WorldOzoneDay #MondayMotivaton #ClimateChange pic.twitter.com/kOWL6pMJdE

Thanks to the Montreal Protocol and the Kigali Amendment which will help reduce the production and consumption of hydrofluorocarbons, potent GHGs, and thus avoid global warming of up to 0.4°C this century. There is HOPE. #WorldOzoneDay #ClimateChange pic.twitter.com/FserSQW733

This World Ozone Day, while it is great to know that the damage done to the Ozone layer is being reversed each year, we still have a long way to go. Let’s work together to reduce the emission of harmful gases.
