Organizer: Vigyan Setu Foundation Bridging Science & Society
September 16 commemorates the day of the signing of the Montreal Protocol, in 1987. However, it was in 1994, when the United Nations General Assembly proclaimed this day as the International Day for the Preservation of the Ozone Layer aka World Ozone Day. The ozone layer protects life on Earth. We need to safeguard this layer for all of us. As a part of raising awareness about this fragile layer and associated aspects, Vigyan Setu Foundation brings an interesting quiz.
