Question:
At the current rate, how long would it take the ozone layer to disappear and what can we do to protect ourselves with a thinner layer?
Is it possible to regenerate or construction artificial ozone?



Replies:
I do not know how long the ozone will hold out at the present rate, but it would be wise to wear broad brimmed hats, long sleeved clothing, and use sunscreen lotion with a sun protection factor (SPF) of 15 or more. It is probably not possible to create an artificial ozone layer, but the layer would probably regenerate itself if left alone long enough. That is why we are moving toward a global ban on CFC's - the ozone destroying chemicals.

I hope never! Any estimate of such an event should be suspect however. First, we do not know if ozone is disappearing. We do know that we have measured declines in ozone over the poles but we do not know the historical importance of this. In other words, has this happened before and what problems occurred?
