I would say that there's been ample evidence from the Cohen inquiry all the way through that fish farms are a significant problem. If you have a significant problem that you know exists, the precautionary approach would dictate that you don't allow them to continue, just as you don't allow fisheries to take place if you are posing a significant risk. I think there's been evidence that there's significant risk at this point.
