World Ozone Day Quiz 2024: September 16 was declared International Day for the Preservation of the Ozone Layer by the United Nations General Assembly in 1994. In 1987, 46 nations around the world signed the Montreal Protocol on Substances that Deplete the Ozone Layer. It was also known as the “Montreal Protocol”. The theme of this year’s World Ozone Day will be out soon. In the 2023 the theme was Montreal Protocol: fixing the ozone layer and reducing climate change. Not only does the theme support sustainable development, but it also recognizes that the Montreal Protocol has a much broader impact. To check your knowledge on International Ozone Day let’s attempt the Quiz on Ozone Day 2023.
