Ozone Layer Depletion
[ send me this paper ]
A 6 page paper defining the ozone layer, its importance to life on Earth and the mechanisms by which it is depleted. Given that ozone (O3) is a naturally-occurring substance in the Earth’s atmosphere, the debate surrounding whether it is increasing or decreasing superficially seems to be little more than an academic exercise, or alternatively something for militant environmentalists to champion. It is continually created and destroyed by sunlight, effectively absorbing most UV radiation and preventing it from reaching Earth’s surface. Other free radicals, particularly chlorine, disrupt this creation and destruction process, preventing the formation of more ozone after UV light has destroyed it. The paper discusses the hole over Antarctica, the role of CFCs in depleting the ozone layer and positive signs that are beginning to appear more than a decade after developed nations reduced their use of CFCs. Bibliography lists 10 sources.
