Lou,
That study is from an economic think tank. It's not about fish so alot less 'controversial' that Pebble commissioned it and that company does that as their business, reputation does matter for them. Regardless, at least having a data point and study to point to has more value than a view which is (no offense intended) baseless. Your response was effectively "I don't like what it's saying because it goes against what I want to occur so I don't agree with it, but at the same time I don't have any facts to support my view or anyone else's independent view to point to as defense". 

Do you get my point here Lou, it seems alot of people 'choose' to just believe something without having any data or facts to support their views. That is not the way I was taught to think and analyze issues.

And note the implicit assumption you've made that its the mine or fisheries, it seems your bias is showing. Scientific fact suggests otherwise. Oddly you said you had no bias

Best of luck
