The environment means the earth's cover, and the most important part of it is the ozone layer or the ozone shield—about 15 to 35 km from the earth as a colorless gas level. The ozone layer above is mainly found in the Earth's stratosphere, which absorbs the sun's harmful ultraviolet rays. Nature has fixed the need for this armor because the sun's ultraviolet rays and their radiation adversely affect the Earth. The task of stopping them is of the ozone layer.
In the year 1913, the first French physicist, Chalmers, and Henry discovered the ozone layer. They wanted to see the reasons why radiation that reaches the Earth from the sun does not harm the Earth, as the temperature is considered to be about 5500-6000 degrees centigrade. This ozone layer does not allow the ultraviolet rays of the sun's medium frequency to reach the Earth up to its 97-99%, and the Earth is safe from significant damage. Another research in the year 1976 found that the ozone layer is also gradually being destroyed due to human activities. Research on the ozone layer has been continuing for a long time. The research revealed that the main reasons for the destruction of this layer are the gases that are the industries' products. It has two elements, like chlorine and bromine, causing great damage and thin layers. The polar region and Antarctica suffered a more significant impact.
Supersonics are also dangerous:
In the year 1970, scientists studied this research and tried to pursue it. That is why the US also had to suspend supersonic transport, as almost every major aircraft release nitrogen oxide. In the year 1974, American chemist Mario and Sherwood found in a study that chlorofluorocarbon with carbon, fluorine, and chlorine atoms has the highest potential to damage the ozone layer. In furtherance of the same study, Krutzan Molina and Rollan made a major contribution to this work. They were conferred with the Nobel Prize in the year 1995.
Human activities causing harm:
Continuous human activities are causing a lot of damage to the ozone layer. The first address was in the year 1985, after which the Montreal Protocol was adopted in 1987 to check the production and consumption of chlorofluorocarbons, which completely banned this chemical compound. However, not only chlorofluorocarbons but also the holo carbon emanating from refrigerators and air conditioners are damaging the ozone layer.
Future concern for all:
Research published in 1985 indicated that the situation is deteriorating at the rate of 60% as compared to other areas in Antarctica. All this has been before us for almost the last three decades, but despite all these studies, there was a five percent global loss of the ozone layer between 1970 and 1990. It is imperative that there should be debates, discussions, and efforts at every level because the ozone layer is not only of one city or country but also the safety net of all of us.
