Pakistan observes the day to mark the anniversary of its signing of the Montreal Protocol.
Historically, in 1994, the United Nations 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 (resolution 49/114)..
Ozone is a trioxygen inorganic molecule having pale blue color and a pungent smell. Its formula is Oз which means tri oxygen. It is not only a molecule having a pungent smell, it is the protective layer around the earth, the layer which protects the earth from different hazardous gases and attacks of bursting stars in space. Scientists proved that fission reactions are continuously taking place in the sun and other stars. If the chemicals, gases, and other reaction products directly reach the earth, it will be very dangerous for the safety and survival of the earth. Mainly, the ozone layer protects the earth from ultraviolet rays, which are very hazardous for the earth. Ozone is therefore a very protective layer for the earth.
Excessive use of chlorofluorocarbons in our daily life has become main reason of depletion of ozone layer. The main sources of chlorofluorocarbons are refrigerators and air conditioners. These chlorofluorocarbons are responsible for the gradual depletion of the ozone layer. Scientists have observed a hole in the ozone layer which is alarming for the world.
So to create awareness and to acquire environmentally friendly techniques to reduce the use of chlorofluorocarbons, the UN general assembly proposed to celebrate world ozone day, this decision was taken in 1994, and since then world ozone day is celebrated every year on 16th September.
