Is Man responsible for the depletion of the ozone layer?
Indirect evidence in the issue of the ozone layers overall health should be considered also. From 1974 to 1985 UV-b radiation (the main element that we depend on the ozone layer to filter out) remained the same or went down. While this is not 100% proof of overall ozone layer health, it does add credibility to the concept that while some areas thin, other area do pick up that slack and overall volume may be more consistent then alarmists claim. Politics over substance for some though.
