What is it that everything on the planet relies on? Everything on the planet earth relies on how the ozone layer is affected. The air we breathe, the food we eat and the water that we drink. Hopefully by explaining how chlorofluorocarbons (CFC’s) and other chemicals that causes damage to the ozone, which in turn causes skin cancer and other health related issues, it will help humanity better understand what needs to be done to try and save the planet.
Holes, in the ozone layer? How did that happen? There is a chemical called chlorofluorocarbons (CFCs) that travels to the upper atmosphere and breakdowns the protective ozone layer. CFC’s is a man made chemical that has been found in many different items. Here are some example, refrigerants, and solvents in the electric industry, in fire extinguishers, dry cleaning solvents, and degreasing agents and in foam packing and insulation materials. CFC’s were used because in the troposphere they were completely unreactive and did not affect human health. This gave it a long atmospheric lifetime. What scientists did not realize is that the CFC’s were broken down by the UV radiation from the sun. (Dr. Elmar Uherek - Max Planck Institute for Chemistry, Mainz, Germany.)
The stratospheric ozone absorbs the ultra-violet radiation as a result it does not reach the troposphere. What this means is the ultra-violet (UV) light that reaches the earths surface is too weak to breakdown the CFC’s present. Significant amounts of CFC’s have entered the stratosphere and the ultra-violet radiation is strong enough to break the down into a reactive chlorine and fluorine, which is very capable of destroying the ozone. (Dr. John Cowley, 2004-05-06, Rajendra Shende, 2003-10-06 Hendrik Forster and students, March 2004 http://www.atmosphere.mpg.de/enid/1z2.html ) The ozone levels under natural conditions are consistent because they have been formed and destroyed by the ultra-violet light.
