Preservation of Ozone Layer Activity

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. This year’s theme was ‘Montreal Protocol – Keeping us, our food, and vaccines cool.’ Students of class XI and XII explained the importance of this day through Power Point presentations, poems and speeches.
