Young man, you are free to eat as you wish... but please learn/educate yourself on topics at hand before making blanket statements derived from your limited life experience.
Comparing lake O Salmon to Atlantic, is just foolish.. Please refer to statement above.
Food Inc, Food Matters, Earthlings, Blue Gold, etc.. Please watch all of these, then read all the books associated with these topics. Then spend about a decade or more living the lifestyle. Attain enough knowledge to speak with experts like David wolfe, on such subjects/matters... After all this, maybe, just maybe we can have an enlightening converstation regarding this subject.
-Until then.. Godspeed young man
