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
