About International Day for the Preservation of the Ozone Layer

The Ozone Layer is the protective layer of naturally occurring gas, comprised of three atoms of oxygen found about 10 – 15 km above the earth’s surface that protects us from the harmful ultraviolet radiation or UV-B rays of Sun. Scientist in the 1970 found that the layer was thinning and later found an Ozone Hole developed due to the presence of CFC’s. This compels nations to work together and framework co-operative activities to protect and preserve of ozone layer.

On December 19, 1994 United Nations General Assembly designated 16 September as International Day for the Preservation of the Ozone Layer. The decision was made in commemoration of the date, in 1987, on which nations signed the Montreal Protocol on substances that deplete the ozone layer.
