> we humans managed to stop and slightly reduce the Ozone Hole By "we humans" I assume you mean Dow Chemical or whoever the primary inventor of CFC replacements was at the time. Yes, it was a good thing, but there was a relatively easy and uncontroversial fix. What we are talking about here involves people with huge vested interests in fossil fuels - people dependent on them for living and commerce, entire nations solely dependent on them just to function - there are much larger systematic problems at play that must be overcome to reverse the current trend. I'm still mildly optimistic that we can improve the situation, but if the ozone was like steering a rowboat, this is like trying to do a 180 in an aircraft carrier.
