Salmon are one of the wonders of life on earth.
The plight of wild salmon due to corporate salmon farms and the parasites and poisons for which they are responsible is appalling to those of us who have followed the issue. Wild runs are being exterminated by seas lice infestations produced and sustained by so-callled salmon farms. Ecosystems are being destroyed on land and in the water. Traditional and modern ways of life are being wiped out.
There is a wonderful video here. Please view it. If you have a conscience, you will likely never buy farmed salmon again. Good material can be found here and here and (more scientific) here. For a more complete list of published material go here. But the video says it all.
