Question on ozone It seems you have a working knowledge of physics and are interested in ozone   What creates Ozone o  and is it a finite resource   This started by a friend emailing an article from Georgetown on the rate of melanoma and new treatments for same   It got me thinking about what correlation the sunworshipping of the last  years and the rate of ozone depletion both have on the astronomical increase in melanoma I think of natural resources like oil as being finite for all practical purposes   Thanks    Curious
