HELLO MY FRIENDS TODAY I AM ABHINAV IS GOING TO PRESENT ON WORLD`S OZONE DAY
Since 1995, on 16 September each year, the International Day for the Preservation of the Ozone Layer is celebrated. This date has been designated by the United Nations General Assembly in its resolution 49/114, to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer.
This commemoration around the world offers an opportunity to focus attention and action at the global, regional and national levels on the protection of the ozone layer. All Member States are invited to devote this special day to promotion, at the national level, of concrete activities in accordance with the objectives and goals of the Montreal Protocol and its Amendment.
The Ozone Layer describes the protective layer of naturally occurring gas, comprised of three atoms of oxygen found about 10 – 50 km above the earth's surface that protects us from the harmful ultraviolet radiation or UV-B rays of sun. Scientist in the 1970’s discovered that the layer was thinning as a result of the release of CFC’s, consequently, the Ozone Hole developed. In 1985, nations around the world convened at Vienna in an attempt to develop a framework for co-operative activities to protect the Ozone layer. This signed agreement became known as the Vienna Convention for the Protection of the Ozone Layer.
The UNEP is monitoring compliance with the programmes of the international treaties aimed at eliminating the production and use of ozone-depleting substances, including chlorofluorocarbons (CFCs), used as industrial refrigerants and in aerosols, and the pesticide methyl bromide.
Specifically, developing countries need to focus on eliminating the use of methyl bromide as an agricultural pesticide and they must halt illegal trade in CFCs.
More than 130,000 new cases of melanoma are reported around the world and some 66,000 people die from skin cancer every year.

Answer:
September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer . Ozone is a trioxygen inorganic molecule having pale blue color and pungent smell. Its formula is Oз which means tri oxygen. It is not only a molecule having pungent smell, it is the protective layer around the earth, the layer which protects the earth from different hazardous gases and attack of bursting stars in space. Scientists proved that fission reactions are continuously taking place in sun and other stars. If the chemicals, gases, and other reaction products directly reach to the earth, it will be very dangerous for the safety and survival of the earth. Mainly, ozone layer protects the earth from ultra violet rays, which are very hazardous for the earth. Ozone is therefore a very protective layer for earth.
But unfortunately, due to exceeded use of chlorofluorocarbons in our daily life. The main sources of chlorofluorocarbons are refrigerators and air conditioners. These chlorofluorocarbons are responsible for gradual depletion of ozone layer. Scientists have observed a hole in ozone layer which is alarming for the world.
So to create awareness and to acquire environmental friendly techniques to reduce the use of chlorofluorocarbons, 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. This day is celebrated worldwide on national and international levels. Governments of different countries conduct awareness programs and ceremonies to spread the use of environmental friendly and ozone protective products. Different programs are also conducted in schools and colleges to teach young ones how to protect our world. Different activities are managed by the teachers to develop awareness in students, so they can learn the use of environmental friendly and ozone protective techniques.
