Speaking as an Atlantic Canadian and a professional journalist who has covered the commercial fishing industry here for more than two decades, my observation is that sentimentality, in the form of animal rights ideology, is all the anti-seal hunting protest movement and money machine are based on, since there is no scientific fact or conservation reality to support them.
In the rational world, there are at least two compelling arguments in favour of seal hunting in Atlantic Canada:
1. Seals are an abundant, valuable, and renewable resource in a fishery beleaguered by declining stocks of many traditional catch species.
Reality check: seal populations are greater than they've been in at least half a century and a 2002 report in the Canadian Veterinary Journal (Can Vet J 2002;43:687–694) found that "The large majority of seals taken during this hunt - at best, 98 per cent in work reported here - are killed in an acceptably humane manner."
2. The abundance of seals is not coincidental to stock declines of other species, and the seal population must be diminished if there is to be any hope of saving currently threatened fish species, and indeed possible decimation of other species. The marine ecological balance is indisputably out of whack and dysfunctional, but allowing one species whose natural predators (eg: sharks) no longer exist in numbers sufficient to sustain a healthy balance to proliferate unchecked is emphatically not going to improve things.
Aside from sentimental idiocy fostered by the unquestionable cuteness of whitecoat seal pups (which haven't been hunted in Canada since 1987), there is no rational reason not to hunt seals if there's a market for seal products, and bringing the seal population down from its current record levels is ecologically beneficial. Besides seal predation of vulnerable and valuable fish stocks, they are also damaging fishing gear and are an incubator for worms that infest other species.
Of course, neither of these logical conclusions will ever convince the fanatical animal rights zealots of People for the Ethical Treatment of Animals (PETA), the Humane Society of the United States, the International Fund for Animal Welfare (IFAW), and celebrity fellow-travelers like Sir Paul McCartney, Pamela Anderson, and Brigitte Bardot, whose objection to seal hunting is based on emotion and ideology - not logic and reason.
According to the Canadian government, sealing is an important source of employment for about 12,000 Canadians, most of whom live in economically-depressed regions with little scope for alternate enterprise Swiss psychologist Carl Gustav Jung once observed that "Sentimentality is a superstructure covering brutality." Now brutality is a term the anti-sealing crowd like to fling at hunters, but in my estimation real brutality characterizes those who would sacrifice the livelihoods and wellbeing of 12,000 sealers and their families and communities in favour of banning the harvest of a renewable resource that is experiencing a population explosion to the tune of 12 percent annually..
