Montreal Protocal

Montreal protocol : Mitigating Ozone Depletion through Science and Global UnityThe implication of ozone depletion is among the precisely about devastating occurrences that suffer been advantagefully mitigated and prevented beca commit of scientific discipline and worldwide cooperation . This has been made possible because of the Montreal Protocol , an international treaty that seek to address the sheer 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 declension in the use of ozone depleting substances . This is an effort to describe how the Montreal Protocol has been self-made in mitigating the effect of an environmenta l 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 disc all overy in the global concern over the depletion of the ozone class was founded on two scientific studies : the 1970 study of capital of Minnesota Crutzen who argued that the nitrogen oxides from fertilizers and ultrasonic aircraft can deplete the ozone stratum and that of brusk Sherwood Rowland and Mario Molina who hypothesized that the compound chlorofluoro carbon copy (CFC ) used in the production of pliant foams , and for coolants in refrigeration and air conditioning systems has a effectiveness to reverse the ozone layer . According to them , CFC is so torpid that they can pull round in the melodic line and bump off 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 barge in the stratosphere decomposes the ODS molecules releasing chlorine atoms or bromine atoms . centiliter atoms and bromine atoms that were released during the decomposition of the ODS molecules then destroys the ozone layer . Since the ozone layer absorbs near of the ultraviolet-B (UV-B radiation from the sun , the depletion of the ozone layer would have dangerous wellness , 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 constitution on June 28 , 1974 , paved way to shape up studies and in 1976 , the National Academy of Sciences finally confirmed their possibility . 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
