International Day for the Preservation of the Ozone Layer also known as World Ozone Day or simply as Ozone Day is celebrated on September 16. It is a UN observation and it commemorates the signing of the Montreal Protocol on substances that depletes 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.
The principal aim of the Montreal Protocol is to protect the ozone layer by taking measures to control total global production and consumption of substances that deplete it, with the ultimate objective of their elimination on the basis of developments in scientific knowledge and technological information.
The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet. Life is not possible on Earth without the ozone layer.
