How far have environmental issues slithered down the greasy pole of public anxiety?

I would not draw the conclusion, however, that people's concern about LEGITIMATE environmental issues has taken a hit. That remains to be seen. If concern over the environment in general takes a hit, then I'd blame the AGW proponents for destroying the credibility of the entire environmental movement, not the AGW detractors, many of whom do care about the environment, as do I.
