Why would that be such a surprise? If scientists give government the power to act based on their findings, then they're giving it the power to act based on whatever findings they choose. It has always been this way with government. Why would you give someone a gun if they have a history of pointing it in absurd and dangerous directions?
Well, there is the fact that salmon don't spawn on the eastern seaboard any more, in science a determination is made based upon observable statistics, it will always be a political decision what level of risk is tolerable. Such as if the slamon fishery is important enough to clean up the rivers on the east Coast.
Take arsenic in the drinking water as a prime example, there is a risk for low levels of arsenic in drinking water, we are currently in a political process that is determining if the risk is balanced by the cost.
Ah rememeber the good old days when scienece was just the handmaiden of industry and we were told that somking tobacco was good for us? Like the guy who invented the liquid lead in gasoline saying that it wasn't toxic.
Right now there is the issue of mercury trading for emissions standards, I feel that it is a poor idea, given the fact that they are now revising the rules on refitting old power plants. I don't really like the idea that there will a be a trade off where the health of certain children will be damaged by mercury, just so someone else can not emit mercury. Mercury is a risk, but if (and that is a big if) it gets the coal burning plants to actualy reduce emissions of mercury then it is a good thing.
Our system is based upon compromise.
It is very good science that green house gases are slowly raising the earth's temperature, but there is still some debate amongst politicains if that is so. it is not much of a controversy amongst the scientists. So again we have a political process that determines acceptable risk, I don't like it, but it is about the best we could ever get for a system.
Fortunately GWB is not as wrong as the germans were prior to WWII, we don't have loyalty police on theorhetical science yet.
