Has the size of hole in ozone payer changed in recent years
Answers
The ozone layer is vital for the continuation of much of life on earth - its protective effect stops harmful UV-C radiation from reaching the surface. Whilst some of our efforts may have had unintended consequences , the struggle still remains to ensure that the existing hole does not continue to grow.
The data below shows that since the Montreal protocol came into force, the size of the ozone hole has increased in size by 36%. The hole was around the size of Cuba in 1979 (130,000 sq km) and has grown to the size of North America today (25 million sq km).
Chlorofluorocarbons (CFCs) are largely to blame. Once they reach the upper atmosphere the sun's rays breaks them down, releasing highly reactive chlorine atoms. Chlorine breaks down ozone and disturbs the natural cycle which prevents harmful rays from reaching the earth's surface.
It is hoped that the ozone layer will be able to recover in as little as 50 years due to the decrease in use of CFCs.
Yes because of the Pollution in our country the chemicals affect ozone layer and due to the festival Diwali the pollution caused by crackers affect the ozone layer and breaks the layer . This has caused so much damage to health to that people in our country as the path has cleared for UV rays to enter. Please mark it as brainliest answer
