World Ozone Day
World Ozone Day is observed on September 16. It is also known as the International Day for the Prevention of the Ozone Layer. It marks the anniversary of Montreal Protocol that was brought forth by the global community to regulate the ozone depleting substances.
The theme for this year’s World Ozone Day is “Montreal Protocol Keeping us, our food and vaccine cool”. The Montreal Protocol aims to promote international cooperation in protecting the ozone layer – a layer of gas in the Earth’s stratosphere that absorbs 97 to 98 per cent of the UV rays from the Sun and maintain the ozone-oxygen cycle.
