Ozone Depletion Essays -- essays research papers fc

Ozone DepletionA graphic symbol forIgnoring the FactsOzone forms a layer of the earths atmosphere that protects us from the insolates deadly ultraviolet rays. During the last decade on that point has been a scare set forth by environmental enthusiasts that Chlorofluorocarbons (CFCs) destroy the ozone layer. Although on that point has been no evidence of any CFC destruction of the ozone layer there is an international stoppage on using CFCs, as well as an executive commit set forth by Clinton to limit the portion out and use of CFCs in the United States. These bans are unnecessary , since they are simply based on fear and politics. Basing the ban on evidence stand not be possible, because there is no factual evidence.This executive order is not only futile, unless ridiculous. Facts are the ozone layer is not depleting payable to CFCs or any other manmade chemical. Qualified scientists have proven the intact notion of the ozone layer is not something fixed and finite to be undo faster and slower rates. It is simply not a depletable resourcefulness like a fossil fuel. The process by which CFCs are so-called to deplete it is highly speculative and has never been observed to take place, and however if it did, the effect would be small compared to what happens naturally.Ozone is dynamic. It is constantly existence created and destroyed, and as immense as the sun emits rays the process will continue. Ozone is the Trioxide molecule (O3), which is created by photons radiated from the sun. A normal oxygen molecule (O2) consists of two oxygen atoms, in diatomic form. High energy ultraviolet radiation known as UV-C crowd out split one of these molecules, through a process known as photodissociation, into two free oxygen atoms. These atoms then join with a thirdly oxygen and form ozone. Some ozone is found at ground level, but most occurs in the Ozone Layer, a concentration of O3 approximately 30 miles preceding(prenominal) the Earths surface. Most ozon e is produced in the tropics where ultraviolet conflate is the strongest.Ozone is destroyed by chemical reactions that convert the O3 molecule into O2. The reaction that causes this is by and large nitrogen dioxide (produced in part by high altitude cosmic rays), through ultraviolet dissociation by the same UV-C that creates ozone, and also by a less energetic band know as UV-B, which... ...e detrimental effects of CFCs are in the tens of thousands, there are no grants to line of business the positive effects of ultraviolet flux. It is curious that all the grant proposals create verbally by scientists concerning the other side of the CFC issue are being turned down. Is ozone depletion created by political/economical issues? It has not been proven by factsjust ignoring the facts. All this while the media plays on the fears of the general public. As pier Holzknecht, a CFC engineer for twenty years observes, Nobodys interested in reality. Everyone who knows anything stands to gai n. The public will end up stipendiary through the nose, as always, but the public is unorganized and uniformed.BibliographyBegley, Shannon, Is the Ozone Hole in Our Heads?
