September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer (Ozone Day). 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. In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer.
World Ozone day 2020. This year, we celebrate 35 years of global ozone layer protection. For Year 2020 The theme is “Ozone for life”, with a supporting slogan “35 years of ozone layer protection” reminds us that ozone is crucial for our life on Earth and we must continue to protect the ozone layer for our future generations also.
The closure of the hole in the ozone layer was observed 30 years after the protocol was signed. Due to the nature of the gases responsible for ozone depletion their chemical effects are expected to continue for between 50 and 100 years.
No Ozone layer no life on the Earth. World Ozone day 2020
