Earlier quoted context omitted.
Well, every year in the US 121 million pigs are slaughtered, and they obviously live under much worse conditions. The Faroe Islands have 50000 inhabitants, so even if they did this every year it wouldn't really be very significant. It looks graphical, but if they eat them, which I understand that they do, what is really the problem?
This would make some sense if we were farming dolphin. Pigs are not endangered.
