World Ozone Day or International Day for the Preservation of the Ozone Layer is a global event held annually on September 16 to promote awareness about the ozone layer's significance and the dangers of its depletion.
History of World Ozone Day
The date of the world ozone significantly goes to the 1980s when scientists realized that there was a reduction in the ozone layer due to certain human-made chemicals such as chlorofluorocarbons (CFCs) and halons. This dire realization led to concern about the impacts that might ensue from the depletion of the ozone layer on man as well as the environment.
In response, the Montreal
Protocol was signed on the 16th of September, 1987 aimed at eliminating
production of the ODS. The protocol has been ratified by all the member states
thus placing it among the most successful environmental conventions in history.
Significance of the Ozone Layer
The ozone layer is a thin shield of gas in the Earth's stratosphere that
absorbs most of the sun's harmful ultraviolet (UV) radiation. It plays a
crucial role in protecting life on Earth by preventing excessive UV radiation
from reaching the surface, which can lead to higher rates of skin cancer, eye
cataracts, and ecosystem damage.
