Background:
September 16, 1987, also known as World Ozone Day, commemorates the day of the Montreal Declaration on Reducing the Production of Harmful Ozone by 24 nations. Such harmful elements include chlorofluorocarbons and 94 other chemicals. This World Ozone Day has been celebrated since 1995.
Remember that ozone, about 15 to 30 km above the Earth's atmosphere, is a protective shield. This prevents the sun's harmful rays from entering the earth directly. Due to human activities and uncontrolled industrialization and the use of excessive chemicals, such ozone layers have begun to deplete and perish.
Ozone Depletion
Remember that the depleted ozone layer cannot be repaired by humans on their own, and the conservation of ozone is essential for the protection of human beings and civilization. The protection of the zone level requires the availability of reliable means of public transport and the promotion of low fuel consumption means such as bicycles and pedestrians. Similarly, body perfumes and perfumes used in factories are considered to be the primary cause of ozone depletion. Such a substance is called spray aerosol which has been used in the industry for over fifty years.
Such sprays contain chlorofluorocarbons, which reach the ozone layer and combine with the parasitic layer to destroy the ozone and convert it into chlorine. One such molecule of chlorine destroys thousands of ozone molecules.
Without ozone, the sun's harmful rays can lead to an increase in cancer and other diseases, negatively affect the life of aquatic and terrestrial life, and endanger human existence as a whole. In other parts of the world, 20 percent of the ozone layer is depleted, but over Antarctica, 80 percent more ozone has been depleted due to cold weather and chlorine depletion.
This reiterates the recent finding by the Scientific Assessment Panel of the positive impact the Montreal Protocol has on climate change, that ozone recovery is on track and how climate challenges can be supported through the Kigali Amendment.
The theme is decided to save the life of people who survive on the Earth to make protect the ozone layer and our environment.
Meaningful wishes on this day.
