It's important not lump dissimilar things into the same pile. Cap and trade and etc., is about economic power. If global warming is not a real environmental concern, that does not preclude that there are any real concerns. Do not lump them all into the "environmental wacko" pile.
You know, extremes define the center. Realizing that will keep you from being down on a particular extreme too much.
Another thing, "environmental wackos" are frequently criticised when they're out to preserve some insignificant species. An endangered minnow, say. The reason they do that is because the development that would endanger that species has to be fought with something tangible. The real concern might be a company selfishly destroying for all time some part of our heritage, not the minnow itself. Use every weapon.
In other words, if somebody wants to turn Daniel Boone's homeplace in N.C. and the whole Yadkin Valley into a mall complex and McMansions, pray that someone can find some endangered 1/2" long fish that would be negatively impacted by it.
