International Day for the Prevention of the Ozone Layer 16-Sep. 2021
International Day for the Preservation of the Ozone Layer 2021 Theme. This year's theme for the International Day for the Prevention of the Ozone Layer is 'Montreal Protocol – Keeping us, our food, and vaccines cool.
There’s a lot to celebrate: A treaty joined by every
country on the planet that has virtually eliminated
chlorofluorocarbons (CFCs) and dozens of other ozone-destroying chemicals
worldwide, protecting the fragile stratospheric ozone layer we rely on to
screen out dangerous ultraviolet radiation. The Montreal Protocol is saving
millions of lives and avoiding untold harm to agriculture and other vital
natural systems. It’s also reducing the speed of climate change.
You can visualize what NASA scientist Paul Newman calls
“the world avoided” here:
September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer. This designation had been made on December 19, 2000, in commemoration of the date, in 1987, on which nations signed the Montreal Protocol on Substances that Deplete the Ozone Layer.
In 1994, the UN General Assembly proclaimed 16 September the
International Day for the Preservation of the Ozone Layer, commemorating the
date of the signing, in 1987, of the Montreal Protocol on Substances that
Deplete the Ozone Layer.
The closure of the hole in the ozone layer was observed 30
years after the protocol was signed. Due
to the nature of the gases responsible for ozone
depletion their chemical effects are expected to continue for
between 50 and 100 years.
HISTORY AND SIGNIFICANCE
Humans have
been a threat to the natural paradigm of the blue planet. One of the
consequences of the oblivious actions harming the environment was the depletion
of the fragile layer of gas that protects people on earth from harmful cosmic
rays, called the ozone layer.
The Montreal Protocol was a deal for countries across the globe to curb the existence of all ozone-depleting substances such as aerosols, chlorofluorocarbon, halogens, etc., widely used for cooling and refrigeration purposes. The usage of such harmful substances resulted in a hole in the ozone layers in Antarctica, first discovered in 1970, which led to acute global warming in the past 20 years. source news18

The Montreal Protocol – keeping us, our food and vaccines
cool
The Montreal Protocol started life as a global agreement
to protect the ozone layer, a job it has done well, making it one of the most
successful environmental agreements to date. A united global effort to phase
out ozone-depleting substances means that today, the hole in the ozone layer is
healing, in turn protecting human health, economies and ecosystems. But, as
this year’s World Ozone Day seeks to highlight, the Montreal Protocol does so
much more – such as slowing climate change and helping to boost energy
efficiency in the cooling sector, which contributes to food security
