- Pollution, nitrogen oxide and carbon emissions are reduced in lockdown, they act to damage the ozone layer
- The theme of World Ozone Day this year is 'Ozone for Life', that is, it is necessary for life on earth.
Lockdown relief can be termed as an ozone layer protecting humans from many life-threatening diseases. The effect of the lockdown in the country has also contributed to the ozone layer.
According to research by Indian scientists published in NCBI Journal, in some countries of the world, there has been a 35 percent reduction in pollution and 60 percent reduction in nitrogen oxide since the lockdown since January 23. At the same time, the emission of carbon, which damages the ozone layer, also decreased by 1.5 to 2 percent and the level of carbon dioxide also decreased. These are factors that damage the ozone layer.
In the beginning of the month of April this year, there was also news that the biggest hole on the ozone layer has recovered. The scientists confirmed that the hole with a circumference of one million square kilometers above the Arctic has closed.
A full report is yet to come on how much relief the sun's dangerous ultraviolet rays have received in this coronary layer. According to environmentalist Shams Parvez, Emissions of carbon and other gases that damage the ozone layer during the lockdown have been reduced by up to 50%, with positive effects expected in the future. During this time, air traffic has come down to 80, which are a good sign at the moment. Today is World Ozone Day, on this occasion, know why it is important and whether the rising temperature will affect it ….
Understand these 5 things about the ozone layer before the news
1. What is an ozone layer?
There are two types of ozone layer. One is beneficial and the other is harmful.
1. What does it mean to have a hole in the ozone layer?
If there is a hole in this layer, the ultraviolet rays of the sun will reach the earth directly. These rays increase the risk of skin cancer, malaria, cataract and infectious diseases. If the scope of the ozone layer decreases by 1 per cent and ultraviolet rays reach 2 per cent of humans, then the risk of diseases can increase substantially.
3. Why the damage to this layer?
4. How are ozone-depleting particles formed?

5. How World Ozone Day started
The United Nations took the initiative to prevent erosion in the ozone layer. On September 16, 1987, an agreement was reached between several countries in Montreal, Canada, called the Montreal Protocol. It started on 1 January 1989. The goal of this protocol was to control chemicals that damage the ozone layer by the year 2050. According to the protocol, it was also decided that the production and use of gases such as chlorofluoro carbon that destroys the ozone layer would be limited. It also included India. The theme of World Ozone Day this year is 'Ozone for Life', that is, it is necessary for life on earth.
Ozone gas causing harm to humans decreased or increased?
The 6-month lockdown has reduced pollution levels by more than 50 percent, but ozone gas levels have come down by only 20 percent. In response to why its level was so high, says Shams Parvez, sodium hypo-chloride was used to sanitize the sites during lockdown. This did not drop the level of ozone gas produced at the breathing level as it should have fallen.
The temperature of the world is increasing, how will it affect the ozone layer
There is no connection between the rising temperature in the world and this layer. The temperature of the atmosphere rises when particles in the environment absorb the sun's heat due to pollution. They contain the most carbon. Due to high pollution in South Asian countries, the temperature is increasing even more.
