Once, dangerously thin, the Ozone layer has been healing slowly since recent years, fortunately with a great stand of the 1989’s Montreal Protocol. The agreement took the countries out from the most dangerous chemicals that were responsible for destroying ozone and allowed to rebuild the protective UV shield of the planet.
But Montreal Protocol left a chemicals group that researchers believed at that time too short living to pose damage. Now, those chemicals are getting produced in the East Asia, while new research says that it will be carried by the seasonal air currents at enough high to threat the ozone layer.
The ozone layer lies around six to ten miles above the surface of earth, which is a region called as ‘stratosphere’. Earlier research suggests a fact of the time during the winter of Northern Hemisphere, when the cold surges were rapidly polluted the air from the parts continental East Asia and China in to tropics, to where the stratosphere could be pushed.
This study added more values to the new hypothesis with the help of air samples that were collected by the ground level of the Malaysia and Taiwan as well as from the airplanes crossing Southeast Asia.
A leading researcher, David Oram from the University of East Anglia said that, “Ozone depletion is a well-known phenomenon and, thanks to the success of the Montreal Protocol, is widely perceived as a problem solved. Generally, thought to be too short-lived to reach the stratosphere in large quantities. This was a major surprise to the scientific community and we were keen to discover the cause of this sudden increase. We expected that the new emissions could be coming from the developing world, where industrialization has been increasing rapidly.”
