Ozone is finally healing, a big thanks to the ban on chemicals and harmful toxics

“International ban on chlorine chemicals that damage the ozone layer have helped to control ozone depletion”. This is a statement given by the NASA scientists. They further added that chlorine chemicals containing artificial chlorofluorocarbons (CFCs) harm the ozone layer.

CFC is a long-lasting chemical substance, which eventually goes to the stratosphere, where the sun’s disintegration from ultraviolet rays breaks. Ozone molecules are destroyed by the chlorine atoms coming out of this fragmentation.

Sussanne Stahan, a scientist and lead author working on atmospheric events at NASA’s Goddard Space Flight Center in Maryland, said, “We see very clearly that chlorine emitted from CFCs in the ozone hole has decreased and for this reason the depletion of the ozone layer is decreasing and it is in the process of healing . ”

Scientists say that due to restrictions on CFC, the reduction in ozone hole during the winter in Antarctic from 2005 to 2016 has reduced by nearly 20 percent, while the chlorine level decreased 0.8 percent annually.

Parasympathetic ozone protects life on Earth. Actually it absorbs the deformation of the sun’s dangerous ultraviolet rays. People are at risk of skin cancer, cataracts, deficiency of immunity by the radiation of ultraviolet rays. They also damage the vegetation and have many harmful effects.

The opening of the hole in ozone in the Antarctic occurs in the southern hemisphere in the month of September, because the ozone acts as a catalyst in the tubercle cycle, due to the return of the rays of the sun, in which the chlorine and bromine emitted from the CFC is included.

From the beginning of winter to the end of winter in the Southern Hemisphere i.e. from the beginning of July to mid September, changes in the ozone levels above the Antarctic were calculated from the microwave limb sounder (MLS) daily from 2005 to 2016.
