Ozone DepletionA Case forIgnoring the FactsOzone forms a layer of the earths atmosphere that protects us from the suns deadly ultraviolet rays. During the oddment decade in that respect has been a sc be set forrader by environmental enthusiasts that Chlorofluorocarbons (chlorofluorocarbons) destroy the ozone layer. Although there has been no evidence of any chlorofluorocarbon destruction of the ozone layer there is an international stoppage on using CFCs, as well as an executive order set forth by Clinton to limit the sell and use of CFCs in the United States. These ousts argon unnecessary , since they are merely based on fear and politics. Basing the ban on evidence can not be possible, because there is no factual evidence.This executive order is not only futile, but ridiculous. Facts are the ozone layer is not depleting due to CFCs or any other manmade chemical. fitted scientists have proven the whole notion of the ozone layer is not something quick-frozen and finite to be destroyed faster and slower rates. It is simply not a depletable resource like a fossil fuel. The carry through by which CFCs are supposed to deplete it is highly speculative and has never been observed to take place, and even if it did, the effect would be small compared to what happens naturally.Ozone is dynamic. It is invariably being created and destroyed, and as long as the sun emits rays the process result continue. Ozone is the Trioxide molecule (O3), which is created by photons radiated from the sun. A normal oxygen molecule (O2) consists of twain oxygen atoms, in diatomic form. High energy ultraviolet radioactivity known as UV-C can split one of these molecules, through a process known as photodissociation, into two free oxygen atoms. These atoms and then join with a third oxygen and form ozone. Some ozone is entrap at ground level, but most occurs in the Ozone Layer, a ducking of O3 approximately 30 miles above the Earths surface. Most ozone is produced in the trop ics where ultraviolet flux is the strongest.Ozone is destroyed by chemical reactions that interchange the O3 molecule into O2. The reaction that causes this is mostly 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 stage set know as UV-B, which... ...e negative effects of CFCs are in the tens of thousands, there are no grants to study the positive effects of ultraviolet flux. It is comic that all the grant proposals written 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 unexclusive. As Bob Holzknecht, a CFC engineer for twenty years observes, Nobodys interested in reality. Everyone who knows anything stands to gain. The public ordain end up paying through t he nose, as always, but the public is unorganized and uniformed.BibliographyBegley, Shannon, Is the Ozone Hole in Our Heads?
