Biggest Arctic Ozone Hole

The biggest Arctic ozone hole detected in mid-April 2020 has now been closed. The results are absolutely astonishing as it was huge in size. Many people are of the belief that the lockdown amid the coronavirus outbreak caused it. In fact, the low level of air pollution led to the closing of the biggest ever ozone depletion. However, scientists believe that despite the lockdown leading to less air pollution.

The reason for it was not pandemic restriction. A plausible reason given by the researchers was that an unusual polar vortex cured the massive hole in our atmosphere. Nasa scientist told that this once in a decade appearing hole is thrice the size of Greenland.

It is very common in the Antarctic region for ozone layers to deplete due to the high emission of chlorofluorocarbons. The activities of the factories and vehicles have caused immense pollution. Nevertheless, the Covid19 did give the environment some relief from the harmful gases. Nature is enjoying this time away from the pollutants. In addition, the rare hole did not cause much damage and in no time closed.
