Recovery of stratospheric ozone layer is necessary for protection of life on Earth, as it filters the harmful UV rays emanating from the sun.

In recent years, the concentration of dichloromethane in the atmosphere has doubled, and it has now begun to significantly affect the behavior of the ozone layer, slowing its recovery. The strength of dichloromethane in Antarctica is actually relatively low, since its main sources are located in the Northern hemisphere. There, as environmentalists suggest, it has a much stronger effect on the state of the ozone layer. According to scientists ' calculations, a further increase in its share in the air can push the recovery time of the ozone layer 30 years into the future at best, and even completely stop it in the most negative circumstances. Moreover, even if dichloromethane were completely stopped from being used today, its presence in the atmosphere would already slow down the tightening of the ozone hole over Antarctica for five years.

For this reason, scientists are calling on governments all over the world to conclude a new agreement similar to the Montreal Protocol, under which all substances, including dichloromethane, that are currently present in the atmosphere and participate in the resolution of ozone, will be banned.

The hole in the ozone layer is closing slowly but surely.

The ozone layer exerts its protective effect on life on Earth by limiting its exposure to ultraviolet rays. And, once is not custom on the front of the protection of the environment, the news in the matter is good. The hole closes at its own pace but on a regular basis.

Today, a report by experts mandated by the United Nations is particularly optimistic. Since 2000, the ozone layer has been replenishing at a rate of 1 to 3% per decade. What hopes to return to the level of the 1980s from the decade 2030 concerning the Northern hemisphere. Rather in the 2050s for the southern hemisphere and a decade later on the side of the polar regions.

Some are already ready to qualify the Montreal Protocol as the most successful global environmental protection in history. "But we must not declare victory too quickly," warn the scientists. Recent studies indeed report a worrying increase in atmospheric concentrations of CFC-11, one of the substances prohibited by the protocol.

Experts also note that the re-establishment of the ozone layer over Antarctica could worsen the effects of climate change there. It remains to be seen how much ...

Few days ago Nature published an article, informing us that over Arctic ozone hole opened up due to cold temperatures and a strong polar vortex which have allowed high-altitude clouds to form. These clouds included ozone destroying chemicals, I think we need to reduce our pollution much much more and faster.

This is quite interesting to note that, all will be in safe, clean and good environment as Mother Earth recovers ozone layer.

Certainly, I am very happy with this joyful news, and I hope that the ozone layer will continue intact and that the problems will not return to it after the end of the Covid 19 crisis.

It is crucial to achieve environmental balance and wellbeing.

Ozone layer recovery helps to resist global warming and prevent skin diseases.

Nowadays the layer of Ozone is recovered significantly because of stopping all the carbon releasing factories due to COVID-19

Ozone layer protects the Mother Earth from health hazards and gives good and pure environment. This can be controlled by restricting harmful emissions into atmosphere thereby preventing global warming.

Dear Dr. Pisipaty Srinivas Kishore

It is good and necessary.

Best regards

Dear Dr. Mohamed F. Al-Dawody
