In regards to current overfishing of cod, that is not being done by Newfoundlanders. They are not allowed to fish for cod commercially, and the quota for sport fishermen is very small. But commercial fishing boats from other countries are not prevented by the government of Canada from over fishing in the waters near Newfoundland. The Skipper (my father-in-law) said that he wishes Canada would respond to this problem the same way that Iceland has done - confront ships from other countries that are overfishing Newfoundland waters. That would help the recovery of the cod stocks. But it doesn't seem likely to happen for some reason.
And Lonesome EJ, not only was that comment about sport a straw man in the way that meself suggested, it's also a straw man in that it mischaractarizes the methods used by most sealers. It is correct to say that most seal fishermen kill young seals who are independent of their mothers using guns, and they do it for livelihood and for food. It is a lie to suggest that most seal fishermen bash in cubs' heads for sport or for the fur industry.
By the way, why are you not protesting the fur industry when other animals are being killed and made to suffer in other places? Foxes raised for fur, for instance, are killed by an electrode that is inserted into their rectums or their mouths and they are electrocuted. Where is your moral outrage about this practice? How about trapping for fur? Animals caught in traps often chew off their own limbs to get free of the traps that are causing them excruciating pain. And those fur animals do not get used for food, unlike the seals in eastern Canada.
The reason people are picking only on the people of eastern Canada, is because they are an easy target. Hardly anyone in the US knows anyone from that part of the world, so people can make the kinds of scurrilous accusations against them that you are making easily without suffering any consequences. It would be very different (and I would suggest, would actually require some courage) for you to confront the people who are doing much worse things in your own community and country.
