Ozone discussion

I asked my father his thoughts about ozone, and he was aware of the aerosol spray issue, and that people can get sunburned more easily due to depletion of the ozone layer. My impression was that he had the understanding of ozone that was common about 15 or so years ago, in spite of reading the news way more than I do. I am really puzzled how he has managed to not know more about this. It seems to illustrate the general denial that has been widespread about this issue, which I HOPE people are finally getting over. I also think that in the fairly conservative area of New York where he lives, people just don't talk about ozone, whereas it's a much hotter topic in northern CA.
