Arctic’s ozone thinner by 40%

The Ozone Layer that keeps out the sun's Harmful ultra violet Radiation Reaching Earth's Surface is found to be getting Thinner about record 40% percent drop in Winter season of Arctic Region, announced world weather organisation.
This Sudden loss In Ozone is so threating That has never been Recorded in Past 15 which exceeded the Previous loss amounts of 30 percent in various seasons, said an official of Un's Meteorological organisation.

Formation and Importance Of  Ozone
Ozone is formed when oxygen molecules absorb ultraviolet photons and undergo a chemical reaction known as photo dissociation or photolysis, where a single molecule of oxygen breaks down to two oxygen atoms. The free oxygen atom (O), then combines with an oxygen molecule (O2) and forms a molecule of ozone (O3)

Ozone one plays a vital Role in protecting the Humans from ultraviolet Radiations,By Absorbing Them  without which Serious Health Hazards Could happen like cancer, cataract and It Also effects Immune System. Not Just Humans uv Rays can destroy Certain Crops and Makes life difficult to Sea Animals.

 Ozone depletion :
Ozone Depletion is One Of The Serious Enivronmental Concerns which is Often Discussed And Worried About!! The Ozone layer depletion first captured the attention of the whole world in the later half of 1970 and since then, many discussions and researches have been carried out to find out the possible effects and the causes of ozone depletion. Many studies have also been directed to find out a possible solution.
The increasing concern for the causes and effects of ozone depletion led to the adoption of the Montreal Protocol, in the year 1987, in order to reduce and control the industrial emission of chlorofluorocarbons and Its usage In Refrirators.
Despite Of this Treaty the Loss In Ozone Has'nt Stoppped Yet.!!
That's So Disturbing we need To Protect Our Environment if It Continues like this The Life Beocomes Critical!!usage of CFC's Should be Reduced !!
WMO noted that even though this Arctic winter was warmer than average at ground level, it was colder in the stratosphere than for a normal Arctic winter.

The agency also pointed out that although the degree of Arctic ozone destruction in 2011 is unprecedented, it is not unexpected. Ozone scientists have foreseen that significant Arctic ozone loss is possible in the case of a cold and stable Arctic stratospheric winter.
