Every once in a while a documentary comes out that makes you think about things in a different light.  Patagonia has just released one that does precisely just that; make you think about the ramifications of mankinds actions in regards to sustaining fish and the effects on wild fish.  I strongly recommend you all watch this video and donate to Change.org to help defend wild salmon and orcas.  You can do so very easily by texting PROTECT to 40649.  The theme here has much greater reach than the effects of farm raised salmon, you could apply much of the same to the stocking of trout and other species as well.
