This is correct (sort of), no one has proven CFCs affect the ozone layer
(its hard to come up with good experiments) and so far the results of the
global experiment (banning the use of CFCs) has been uniformly negative.
[measurable differences in the detectability of CFCs and no measure change
in the behaviour of the ozone.]

The next great disaster headed our way is banning the production of CO2,
aka the "greenhouse" gas.
