Alarm bell! The hole in the ozone layer is bigger than Antarctica, ultraviolet radiation can become a problem

The hole in the ozone layer has become bigger than Antarctica in the year 2021. It is increasing every year. Its information has come to the fore when a month ago it was decided to uphold the Montreal Protocol to protect the ozone layer and prevent the Earth from warming by one degree Celsius. Scientists from the European Union’s Copernicus Atmosphere Monitoring Service (CAMS) said on Thursday, the hole in the ozone layer has increased more in the last two weeks.

Every spring, a hole is formed at the South Pole due to the chemical made by humans, the Earth’s protective ozone layer. Atmospheric ozone absorbs harmful rays coming from the sun to preserve life on earth. In areas with large populations, people living there can be affected by ultraviolet radiation from the hole in the ozone layer. CAMS tracks the annual chemical damage to ozone. For this, the ozone layer is continuously monitored. Due to chemicals, holes are formed in the ozone layer.

75% more hole in the ozone layer

The hole in the ozone layer at the beginning of this season was similar to last year, but it increased in the last two weeks. The hole in the ozone layer has increased by more than 75 percent in this season since 1979. CAMS director Vincent-Henri Puch said the ozone hole could continue to grow slightly over the next two or three weeks. This year the hole in the ozone layer developed as expected at the beginning of the season. It is the same as last year. This did not change much until early September, but later the hole in the ozone layer became one of the largest and longest-lasting ever.

These chemicals are banned under the Montreal Protocol.

In 1987 the Montreal Protocol was signed. Under this, a group of chemicals called halocarbons was banned. Halocarbons contain bromine, which is capable of damaging ozone. At the same time, many commonly used chemicals like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are extremely harmful to the ozone layer. A recent study showed that in addition to protecting the ozone layer, the Montreal Protocol has co-benefits for plants and their ability to store carbon through photosynthesis.
