International Day for Preservation of Ozone Layer to be observed today
Today is World Ozone day, the International Day for the preservation of the Ozone Layer is being observed today. The day marks the commemoration of the date of signing of the Montreal Protocol in 1987 on substances that deplete the Ozone layer.
It is mainly intended to spread awareness of the depletion of the Ozone Layer and search for solutions to preserve it. This year, the theme for the Day is 'Caring for all life under the sun'.
The Ozone layer is a fragile shield of gas which protects the Earth from the harmful ultraviolet radiation of the sun and thus helping preserve life on the planet. Substances like Chlorofluorocarbons, halons, Carbontetrachloride are responsible for ozone layer depletion.
The principal aim of Montreal Protocol is to protect the ozone layer by taking measures to control total consumption of these chemicals. It requires the control of nearly 100 chemicals in several categories. For each group of chemicals the treaty set out a time table for the phase out of production and consumption of those substances.
