The environmental group Sierra Club has long fought against pollution from power plants, but in its latest battle against coal, the group is using misguided rhetoric in an effort to link human exposure from power plant pollutants to tuna. In a new alarmist article to its supporters, Sierra club claims  tuna-sandwich-eaters throughout the country are now being poisoned by coal plants, going so far as to note that  “one-seventieth of a teaspoon [of mercury] can pollute a 20-acre lake to the point where its fish are unsafe.” 

This is not the first time, in reference to a community of extremists, I have noted a quote often attributed to Albert Einstein.  It goes something like this, “The definition of insanity is doing the same thing over and over again and expecting a different result.”
