Depletion of ozone layer can be dangerous to human life. To prevent the depletion of ozone layer a protocol was signed by various nations on September 16, 1987. It is famously known as Montreal Protocol. This day has been marked as the International Ozone Day to commemorate the historic event.
What is Montreal Protocol
The UN General Assembly has declared September 16 as the International Day for the Preservation of the Ozone Layer. The resolution 49/114, proclaiming the decision was adopted on January 23, 1995. It is on this date in the year 1987 that Montreal Protocol was signed on the substances that deplete the ozone layer. The International Ozone Day is to commemorate this historic day and remember our commitment to the nature and the pollution free environment for the future generations. This year marks the twenty first anniversary of the Montreal Protocol that mandates the countries to phase out the ozone depletion causing substances within the specified time period.
In his message on International Day for the Preservation of the ozone layer, September 16, 2008, the UN Secretary General Ban Ki-moon said, “The Montreal Protocol on Substances that Deplete the Ozone Layer, which underpins our efforts to combat depletion of the earth's fragile protective shield, also contributes to combating climate change, since many of the chemicals controlled under the treaty have also emerged as ones that contribute to global warming.

How can I Contribute to Reduce the Ozone Layer Destroying Gases in the Atmosphere
It is the duty of all the citizens of the world to know what causes the depletion of ozone layer and how we can contribute to reduce the emission of gases that cause depletion of ozone layer. The main cause of depletion of the ozone layer are chlorine and bromine atoms that occur in various halocarbons like chlorofluorohydrocarbons (CFCs), hydro chlorofluorohydrocarbons (HCFCs), chloroforms, methyl bromide etc.
By not using the products that contain these ozone depleting gases we can make invaluable contribution to the nature. The CFCs and HCFC gases are found in the refrigerators and air-conditioners. When you are purchasing these products make sure that they are CFC free products.
On International Ozone Day, let us pledge to make sincere efforts for the preservation of the ozone layer for our benefit and the benefit of our future generations. Let us make a resolve to boycott ozone destruction causing products and use only ozone friendly products and services. Let pledge to protect all forms of life on the earth from ozone depleting substances.
