World Ozone Day

World Ozone Day

The World Ozone Day is being observed today in Bangladesh along with the rest of the world. The day is observed throughout the world on September 16 every year since 1995, when it was declared the International Day by the United Nations General Assembly. This year marks the 31st anniversary of the Vienna Convention for the Protection of the Ozone Layer, an important milestone in the protection of the ozone layer.

The use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation. But the challenge has been tackled to a great extent and the ozone layer, which had depleted dangerously has restored thanks to global cooperation in combating it. Nevertheless, continuous and strenuous efforts would be required to make our earth ozone-friendly completely.

The Montreal Protocol has, in fact, established a unique partnership between the developed and developing countries, all striving in unison and harmony to achieve the phase out of Ozone Depletion Substances (ODS). Depletion of ozone layer is one of the most serious environmental concerns threatening the very existence of life on earth. Thanks to the concerted global efforts, the ozone layer was healing and was expected to recover by the middle of this century. In addition, up to two million cases of skin cancer may be prevented each year by 2030 and significant adverse effects on agriculture, wildlife, fisheries and materials have been avoided.

Ozone provides a natural protective filter against harmful ultra-violet rays from the sun, which can cause sunburn, cataracts and skin cancer as well as damage vegetation. And it is encouraging to note that this country is on its way to eliminate the use of Ozone depleting substances. Since most of the ozone depleting substances are also potent greenhouse gases, the elimination of these substances has served to reduce greenhouse gas emissions.  Today, most people are conscious of our environment and how fragile it appears to be. It has led to many movements to recycle, to stop polluting water and air, and to be concerned about the effect that our lives have on our local environment and the planet. Reducing carbon footprints, be it in personal lives or industrial activity remains the key to saving the earth from environmental degradation.
