What is Ozone? Ozone Layer?
Ozone (O3) is a highly-reactive from of oxygen.
Unlike oxygen (O2), ozone has a strong scent and is blue in color.
Ozone exists within both the tropospheric and stratospheric zones of the Earth’s atmosphere.
In the troposphere, ground level ozone is a major air pollutant and primary constituent of photochemical smog.
In the stratosphere, the ozone layer is an essential protector of life on earth as it absorbs harmful UV radiation before it reaches the earth.
CFC’s and ozone depletion
Chlorofluorocarbons are created and used in refrigerators and air conditioners. These chlorofluorocarbons are not harmful to humans and have been a benefit to us. Once released into the atmosphere, chlorofluorocarbons are bombarded and destroyed by ultraviolet rays. In the process chlorine is released to destroy the ozone molecules
