I tend to agree with the polution theory.
Every fish that has hit the deck of my boat appears to have died from a massive concentration of steel polution, usually concentrated near the gill plates....OOOP's.....that was from my gaff. Sorry.
Gent's, its all about greed. Making more money by over harvesting the fish poulation, or using non environmentaly friendly production processes that produce dangerous waste byproducts. Every form of environmental polution or man made environmental damage can be directly attributed to GREED as the cause.
I am in no way a tree hugger, but it is a good idea to step back and look at the big picture once in a while.
Still, I dont see any of us rowing a boat out to the 45 line to hand line our next swordfish while drinking herbal tea and eating tofu and bean sprouts....it just ain't gonna happen.
