(Off Topic) Hey, Mr. Traveling man, sounds like you have been reading a little too much propagada put out by polluters. Your info is twisted! CFC are so deadly to the ozone layer because they are, by nature, extremely stable, and are able to rise to the ozone layer due to the extremely stable nature of the group of compounds. Once there, sunlight breaks down the CFC into a chlorine radical which changes ozone into oxygen. Chlorine compounds from "MOTHER EARTH" typically form HCL and wash out in the rain and never reach the ozone layer. An suppose it is true that most of the chlorine comes from the Earth-so what? The ozone layer is basically being created and destroyed at a equal rate prior to the CFC problem. If only a 1% increase in man made sources occurs-a negative imbalance results-and can you say MELONAMA? For those of you who want a little more info the CFC issue: read this. Human production of chlorine which contains chemicals such as chlorofluorocarbons (CFCs) has added an additional force that destroys ozone. CFCs are compounds made up of chlorine, fluorine and carbon bound together. Because they are such stable molecules, CFCs do not react easily with other chemicals in the lower atmosphere. One of the few forces that can break up CFC molecules is ultraviolet radiation. In the lower atmosphere, however, CFCs are protected from ultraviolet radiation by the ozone layer. CFC molecules thus are able to migrate intact up into the stratosphere. Although the CFC molecules are heavier than air, the mixing processes of the atmosphere carry them into the stratosphere. Once in the stratosphere, however, the CFC molecules no longer are shielded from ultraviolet radiation by the ozone layer. Bombarded by the sun's ultraviolet energy, CFC molecules break up and release their chlorine atoms. The free chlorine atoms then can react with ozone molecules, taking one oxygen atom to form chlorine monoxide and leaving an ordinary oxygen molecule. If each chlorine atom released from a CFC molecule destroyed only one ozone molecule, CFCs probably would pose very little threat to the ozone layer. However, when a chlorine monoxide molecule encounters a free atom of oxygen, the oxygen atom breaks up the chlorine monoxide, stealing the oxygen atom and releasing the chlorine atom back into the stratosphere to destroy more ozone. This reaction happens over and over again, allowing a single atom of chlorine to destroy many molecules of ozone. Fortunately, chlorine atoms do not remain in the stratosphere forever. When a free chlorine atom reacts with gases such as methane (CH4), it is bound up into a molecule of hydrogen chloride (HCl), which can be carried from the stratosphere into the troposphere, where it can be washed away by rain. Therefore, if humans stop putting CFCs and other ozone-destroying chemicals into the stratosphere, the ozone layer eventually may repair itself.
