Montreal Protocal

Montreal Protocol : Mitigating Ozone Depletion through Science and Global UnityThe implication of ozone depletion is among the just about devastating occurrences that suffer been successfully mitigated and prevented beca practise of science and international cooperation . This has been made possible because of the Montreal Protocol , an international treaty that seek to address the issue of the depleting ozone bed . The success of the Montreal Protocol in addressing an environmental issue is app bent in many ways including it being widely proposed for imitation in approaching separate international environmental problems and the major decline in the use of ozone depleting substances . This is an effort to describe how the Montreal Protocol has been successful in mitigating the effect of an environmental issue through science and global cooperation . An outline of the costs , risks and benefits of the treaty is also herein given so as to show how the treaty has remained to be cost good in its effort to address the issue on ozone depletionBackgroundThe discovery in the global concern over the depletion of the ozone class was founded on two scientific studies : the 1970 study of Paul Crutzen who argued that the nitrogen oxides from fertilizers and ultrasonic aircraft can deplete the ozone layer and that of Frank Sherwood Rowland and Mario Molina who hypothesized that the compound chlorofluorocarbon (CFC ) used in the production of plastic foams , and for coolants in refrigeration and air conditioning systems has a potential to reverse the ozone layer . According to them , CFC is so inert that they can pull round in the atmosphere and reach the stratosphere where CFC molecules can be broken down by ultraviolet radiation .

This would progeny to a release of chlorine atoms which , in turn , would destroy large amounts of ozone molecules aggregately referred to as the ozone layer Montreal Protocol page_ 2The Ozone Depletion ProcessThe depletion of the ozone begins when ozone depleting substances (ODS such as CFCs , HCFCs , halons , methyl bromide , carbon tetrachloride , and methyl chloroform are released into the atmosphere . These compounds are so stable they can live on in the atmosphere and reaches the stratosphere after several years . soaked ultraviolet light in the stratosphere decomposes the ODS molecules releasing chlorine atoms or bromine atoms . Chlorine atoms and bromine atoms that were released during the decomposition of the ODS molecules then destroys the ozone layer . Since the ozone layer absorbs most of the ultraviolet-B (UV-B radiation from the sun , the depletion of the ozone layer would have dangerous health , environmental and economical implicationsFigure 1 illustrates the wait on of the ozone depletionFigure 1 .

US Environmental Protection assurance (EPA Montreal Protocol page_ 3The Birth of the Montreal ProtocolThe Rowland- Molina study , which was published on the daybook Nature on June 28 , 1974 , paved way to shape up studies and in 1976 , the National Academy of Sciences finally confirmed their possibleness . By early 1980 s some countries , including the United States and Canada are already exerting their...If you want to get a full essay, order it on our website: Ordercustompaper.com
