Special postal cover to mark Ozone day unveiled in Bengaluru

Prime News, State, (Bengaluru), September 17:-The state-run postal department on Wednesday released a special cover to mark ‘World Ozone Day 2020’ at a function here in the presence of Karnataka Minister for Forests and Ecology Anand Singh, and other officials.
“The special postal cover marks the theme for 2020 ‘Ozone for Life – 35 years of Ozone Layer Protection’, which is observed on September 16 every year,” said state chief postmaster general Sharda Sampath in a statement here.
Sponsored by the Karnataka State Pollution Control Board, the special cover will be available for sale at philatelic bureaus of the main post offices in the city, Mangaluru, Mysuru and Belagavi across the southern state.
“The Ozone day is celebrated to remind the people on the decline of the Ozone layer, to take steps to prevent it and protect the earth,” said Sampath on the occasion.
The United Nations General Assembly proclaimed the World Ozone Day as the international day for preserving the Ozone layer on December 19, 2000, in commemoration of the date in 1987 when nations signed the Montreal Protocol on substances that deplete the Ozone layer was signed in Canada.

The Ozone shield is a delicate layer of gas in the earth’s stratosphere that absorbs most of the sun’s ultraviolet and other harmful rays.
The radiation layer is found in the lower stratosphere, which is 15-35 km above earth, with its thickness varying seasonally and geographically.
French physicists Charles Fabry and Henri Buisson discovered the Ozone layer in 1913.
In 1976, it was found that industrial chemicals like chlorofluorocarbons (CFCs) cause depletion of the Ozone layer, leading to increase in ultraviolet radiation, which is a threat to life on the planet.
The research led to ban chemicals and Ozone depletion was slowed.
