The Falling Sky :: essays research papers
I gave this paper quit a bit of thought I was sitting in a meeting on some air problems here at General Motors and started doing some investigation. tone on this planet Earth is the reaping of a delicate rapprochement act provided by nature.Mankinds rattling existence is all dependent on this fragile ecosystems ability to maintain itself. A valuable player in the balance of the environment, the ozone layer, is facing a very serious threat to man. Chloroflourocarbons (CFCs) are chemicals agents commonly implant in refrigerants, fuel-air bomb sprays, and in the manufacturing of Styrofoam and industrial solvents. With the rate of much than a half-million tons CFCs beingness spewed into the atmosphere yearly, the rate of ozone depletion is rising at an alarming rate. If a orbiculate effort is not made to end the unnecessary use of CFCs, the inhabitants of this establish face an extremely difficult and frightening future. CFCs were invented in Dayton, Ohio in 1928.They were the product of an intensive search by engineers with the G.M. Research Corporation to find a safe non-toxic, non-flammable refrigant. Frigidaire patented the formula CFCs in 1928 and the new wonder assail was called Freon. Seth Cargin and Phillip Dray, co-authors of Between Earth and Sky, informs us in their story of CFCs that Freon presently topped the list of wonders, a miracle refrigerant with the combination of safety, cleanliness, and efficiency(66) non only was the apparently safe gas being used in refrigeration, but with the innovation of air-conditioning by Willis Carrier prior to World contend I, Freon would one day be used to cool our homes, automobiles, and businesses.Other applications for CFCs short followed. Out of the need to eliminate malaria-carrying mosquitoes during the First World War, Freon 12 was found to be an excellent propellant to distribute insecticidethus the contain of the aerosol spray can. From eight aerosol-related companies in the late forties, the industry grew to more than one hundred just a few years afterward (Cagin and Dray 87). CFCs were soon make the lives of millions of Americans much more comfortable. They were also making the Kinetic Chemical Company, a joint corporation of General Motors and Dupont who construct and marketed Freon, extremely wealthy.But in August of 1985, the entire world was conscious by a group of scientist at NASAs Goddard Space safety valve Center that the sky was literally falling. A NASA satellite photo revealed that a portion of the ozone layer the size of the continental United States had disappeared from the atmosphere supra Antarctica.
