International Ozone Layer Protection Day


With the intensification of human activities, there is a serious hole in the ozone layer on the earth's surface, which was discovered in 1974 by Roland and Mulian, professors of the University of California.

The ozone layer can absorb more than 99% of the sun's ultraviolet rays harmful to human beings, and protect life on earth from short-wave ultraviolet rays. Therefore, the ozone layer is known as the umbrella for the survival and reproduction of living things on earth.

On January 23, 1995, the General Assembly of the United Nations decided that September 16 of each year is the International Day for the Protection of the Ozone Layer, requiring all the parties to take concrete actions to commemorate this day in accordance with the objectives of the Montreal Protocol on Substances that Deplete the Ozone Layer and its amendments.

Protecting the ozone layer means protecting the blue sky and the life of the earth.
