A more advanced ozone-monitoring installment will be launched on Europe’s Met Op spacecraft in 2005.
Depletion of the ozone layer allows more of the UV radiation, and particularly the more harmful wavelengths, to reach the surface, causing increased genetic damage to living creatures and organisms.
As far back as human history goes, scientists today have discovered the depletion of the ozone layer and have studied how it is caused by human actions and inventions that affect our environment and style of living.
As the cause of this, many changes have been taking place during the past twenty years or so that humans have and still are concerned of, as they search for new ideas to alleviate this problem.
A valuable player in the balance of the environment, the ozone layer, is facing a very serious threat by man.
Chloroflourocarbons (CFCs), are chemical agents commonly found in refrigerants, aerosol sprays, and in the manufacturing of Styrofoam and industrial solvents.These chemicals were believed to be miracle substances; they were thought to be low in toxics, nonflammable, inexpensive and stable to produce equipments and production such as, refrigerants, solvents, foam blowing agents, and other smaller applications.(1) These substances fused to release chlorine or bromine.Though, these chemicals are used for a certain amount of time, because they break down subsequently and consequently they damage the protective ozone layer which protects the earth from the Ultraviolet light released by the sun.The ozone layer can be depleted by free radical catalysts, including nitric oxide (NO), hydroxyl (OH), atomic chlorine (CI), and atomic bromine (Br).Countries all over the world are studying and taking appropriate measures to prevent the loss of ozone layer.This burning of the skin is caused by ultraviolet (UV) light from the Sun.Serious burning is not only painful, but it may cause skin cancer.With the rate of more than a half-million tons of CFCs being spewed into the atmosphere yearly, the rate of ozone depletion is rising at an alarming rate. Not only was the apparently “safe” gas being used in refrigeration, but with the innovation of air-conditioning by Willis Carrier prior to World War I, Freon would one day be used to cool our homes, automobiles, and businesses. 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 insecticide–thus the birth of the aerosol spray can.If a global effort is not made to end the unnecessary use of CFCs, the inhabitants of this planet face an extremely difficult and frightening future. They were the product of an intensive search by engineers with the G. Research Corporation to find a safe, non-toxic, non-flammable refrigerant. “From eight aerosol-related companies in the late forties, the industry grew to more than one hundred just a few years later” (Cagin and Dray 87).It forms a layer which shields the earth and its inhabitants from the deadly ultraviolet waves emitted by the sun.According to Gordon Keyes with the National Institute of Atmosphere and Water, depletion of this thin layer of ozone not only increases health risks such as skin cancer and suppression of the immune system, it may also cause a decrease in aquatic species and endanger the basic food chain of the ocean (3).
