Show and Tell Time
According to scientists, it takes 35 years for CFC refrigerants to reach the ozone layer.
We should now be seeing the results of the many billions of tons of CFC's dumped into the atmosphere prior to 1973. The Ozone Depletion Theory should now be proveable.
Where is the proof? Specifically, show us the real world harm caused by the release of those CFC's into the atmosphere.Last edited by Gary; 30-11-2007 at 04:24 PM.
