All About World Ozone Day (International Day for the Preservation of the Ozone Layer)!
In 1987 representatives from 24 countries met in Montreal and announced to the world that it was time to stop destroying the ozone layer.
On 16 September 1987, governments adopted the Montreal Protocol to control and reduce ozone-depleting substances, mainly chlorofluorocarbons (CFCs) and halons.
On 19 December 1994, the UN General Assembly proclaimed 16 September to be the International Day for the Preservation of the Ozone Layer.
The ozone layer filters most of the harmful ultra-violet radiation from the sun, which protects from skin cancer and cataracts.
