Actually, greenies, this makes sense

EPA is easing new, more restrictive clean air rules on power plants and so forth.
This actually makes sense. There is a rule of thumb in engineering that says that the closer you get to perfection, the harder it is to make any progress. In other words, the last 10% of the job probably costs as much or more than the first 90% did. (I think there is a name for this rule, somebody’s Law, but I can’t remember it offhand.) And this was going to be very expensive.
The fact of the matter is that the US is not the problem in world air pollution. The Third World (including China) is the problem. And it’s in our best interest to help Third World countries that still burn copious amounts of “dirty” fuel to upgrade their economies so they don’t have to do that anymore, if we really want to do something about worldwide clean air.
