New Threat to Ozone Layer

Ozone layer or ozone shield is a part of the lower stratosphere layer that absorbs most of the sun’s ultraviolet radiation

Our life on the earth has always been a very subtle one. We, the human beings, on one hand, are the creators and also the destroyers on the other hand. The earth has come to be renowned for the people living in it and for the presence of life on it. Has anyone ever thought that we, the human beings, are the only ones responsible for the partial loss of our own? Yes, this is true. When our world was created it was pure and chaste of any pollution, greenery was the very foundation of our Earth. There were ample animals and wildlife of myriad species found. We, the human beings, used to breathe without worrying. Has our world not changed into an unknown place of black land?

We see. We overlook. We try for some time but again return to our old specific forms. We forget that our ozone layer is that very protective layer which prevents the jeopardising ultraviolet rays from torturing us.(Ozone layer or ozone shield is a part of the lower stratosphere layer that absorbs most of the sun’s ultraviolet radiation. The depletion of the ozone layer is a phenomenon that is spotted from the late 1970’s with a steady decline of about 4 percent in the total amount of ozone in the earth’s stratosphere. In addition to these events the researchers have found a new threat that could slow down the process of recovery of the ozone layer from somewhere between 5 to 30 years.)

The chemical that poses the new threat is known as dichloromethane (CH2Cl2). Scientist Ryan Hossaini says that the emissions caused is likely from human sources, and in between the year 2004 and 2014, the concentration of CH2Cl2  catastrophically doubled and the estimate stands at 1 million metric tons per year, which is not at all a good sign for the recovery of the ozone layer.

The ozone layer, which has been ammunition always, is now getting ruined. The ozone layer is being threatened by this abominable phenomenon, the present menace being an emission from the chemical industries working for solvents, paint removers, and pharmaceutical production. Though industrial emissions are also everyday phenomena, this particular emission has an alarming effect. If it is not taken under control now, it will take 30 years for our ozone layer to rebuild itself. Therefore, we should energise ourselves to make the ozone layer stronger and prominent by less emission of hazardous fumes from the industries. We must do it for the sake of saving our Mother Earth.
