Answer:

When was the problem discovered?

In 1974, chemists Mario Molina and Frank Sherwood Rowland discovered a link between chlorofluorocarbons (CFCs) and the breakdown of ozone in the stratosphere. In 1985, geophysicist Joe Farman, along with meteorologists Brian G Gardiner and Jon Shanklin published findings of abnormally low ozone concentrations above the Antarctic.
