| The hole in the ozone layer has begun to close

London: The countries of the world have begun to see results when they come together; The U.N. says that the ozone layer is starting to shrink. Informed. In 2000, the crack was 2.91 square kilometers. This has reduced to 2.31 crore square kilometers. According to the UN report, the crack will be completely closed in 2040 if it continues like this.

The ozone layer is cracked over Antarctica. The ozone layer protects living organisms from harmful ultraviolet rays. Scientists have warned that the reduction of the protective shield will make diseases such as cancer more widespread. The achievement so far will save 20 lakh people from skin cancer every year, according to the UN. Environmental Project Director Inker Andersen announced.

Since the 1970s, the ozone layer over Antarctica has begun to deplete. It was established in 1985. 1987 Prohibition of ozone-depleting chemicals. Chlorofluorocarbons (CFC-11), a chemical found in AC, fridge and insulating foams, play a major role in depleting the ozone layer. With this CFC 46 countries sign the Montreal Protocol to reduce emissions. However, after 2018, CFC-11 emissions have decreased significantly.

The chlorine molecules in CFCs break down the ozone molecules causing the depletion of the ozone layer. It has also been found that the amount of chlorine in the atmosphere has started to decrease. Levels of ozone-depleting bromine have decreased by 14.5 percent since 1993. The ozone layer was expected to reach normal levels by 2066 when CFC-11 regulation was introduced.
