Ozone is the Earth's fragile gas shield that prevents many of the sun's harmful rays from entering the Earth. With high concentration, this layer is the part of the atmosphere that plays an important role in maintaining the health and life of the planet Earth. This World Day is intended to raise awareness of the effects of ozone depletion as well as to find ways to protect it.
Through both natural fluctuations and human activities, a hole has been created in the ozone layer that allows large amounts of harmful ultraviolet radiation from the sun to enter the atmosphere. This hole, which gets bigger in both hemispheres, especially during the spring, prolongs the summer season and causes harmful gases to enter the stratosphere and destroy ozone molecules.
Serious efforts to prevent damage from ozone depletion date back to thirty-one years ago (1987) and the ratification of the Montreal Protocol; But this Earth Shield, which absorbs the sun's ultraviolet rays and protracting life on Earth, won its World Day on September 16, 1994 when countries around the world, with the aim to halt the depletion of the ozone layer, agreed to stop using ozone-depleting substances. This agreement was formalized in the Vienna Convention for the Protection of the Ozone Layer in 1985 and the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987.
Experts believe that if the member states of the Vienna Convention and the Montreal Protocol fulfill their obligations and eliminate the consumption of ozone depleting substances according to the schedule, the natural cycle of ozone formation will return to normal and the ozone layer cavity will be repaired; but in suitable conditions, it will take at least 50 years for this hole to be repaired.
This Ozone Layer Protection Office is the only national executive authority related to the Montreal Protocol programs, which is responsible for coordinating, directing and supervising the proper implementation of programs to gradually reduce and eliminate the import and consumption of ozone depleting substances according to the Montreal Protocol schedule and in the form of a national program.
Each country has a share in this universal effort and Iran is not exempted. Referring to Iran's 2% share of emission of ozone depleting gases in the world, the director of the Ozone Layer Protection Project, said: "More than 1385 workshops and industrial units have been shut down throughout the country.” Also, in the new phase that is being presented to the United Nations, Iran intends to reduce the amount of ozone-depleting gases to 1,600 tons in industry.
Every Small Step Counts:
While the vast majority of ODS usage is either industrial or commercial, individuals can help in the following ways:
- Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process;
- Minimize the use of cars;
- Use Eco-friendly cleaning products;
- Buy local products…
