It is discussed in Science since the 70's. What exactly would you liike to discuss here?

If you want to read up: doi:10.1038/249810a0 is a publication from 1974. You can track the citations of that paper to follow the discussion from the very beginnning.

You can start also here doi:10.5194/acp-18-1379-2018 (A publication from 2018 and follow the referenced papers back)

Ozone has a distinct olfactory quality: yes. (you might have met that with old Laser printers)

A "hole" in this contecxt is a lower concentration of Ozone in that region as in the rest of the world's atmosphere.

Would you care to put forward and discussion points of scientific interest?

One word: chlorofluorocarbons (known as CFCs).

I knew about this in the 80's. Are you really that scientifically ignorant?

It's because the spray cans we used back then had chemicals that went up to the upper atmosphere and degraded the ozone up there which protects us from UV rays.
