NASA news about OZONE layer

Due to the manmade things, the nature is turning like a hell. Of course, even social media are advertising not to use personal vehicles. But, no one following this. Then due to this harmful gases, the Ozone layer's hole is enlarging day by day. Now it went to the size of Antarctica.



The ozone layer which helps shield life on the earth from potentially harmful ultraviolet solar radiation which can cause skin cancer, grows and contrast every year but reached its maximum extent on September 9th.

But scientists remain unsure that, why it was not contrasted even the Montreal protocol agreement was signed in 1987.

Even the Global Trinity banned the ozone-depleting gases of chlorofluorocarbons ( CFCs ) and substances which are used in household and industries such as refrigerators, spray cans and insulation foam.

In the studies at earlier 1990's and 2000's, the ozone layer is normal. But due to the chloro carbons, which are long living in nature made this hole increased.

Due to no interaction between climate Change and the ozone layer makes this happened, the researchers said. The hole itself changing the climate of Antarctica and Australia. And it is changing the wind systems.

By all these effects, by the next 50 or so years, the climate will change drastically, researchers said.

Last month, the UN environment (Unep) and world materilogical organizations (WMO) said that, to recover this hole as like 1980s it can take further 35 years. So, all the countries should follow the Montreal protocol agreement. Then only we can escape from diseases like skin cancer and immune system problems.
