Today is International Day for the Preservation of the Ozone Layer
September 16 is a day observed every year for the preservation of the Ozone Layer.
This year, the theme for the Day is ‘Keep Cool and Carry On: The Montreal Protocol’.
The day was designated by United Nations General Assembly (UNGA) on December 19, 1994. Its observance commemorates the date in 1987 on which Montreal Protocol was signed on substances that deplete the ozone layer.
The Ozone layer is a fragile shield of gas which protects Earth from harmful ultraviolet (UV) radiation of Sun and thus helping preserve life on the planet .
It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere. Stratospheric Ozone is not harmful, but its presence on land it is harmful. Substances like Chlorofluorocarbons, halons, Carbontetrachloride are responsible for ozone layer depletion.
