That's a very good question.
Since 1982, all kinds of steps have been put in place to counter the accusations of animal rights groups and to make sure that the hunt is conducted in a very humane way and that animals are harvested in a professional manner that causes them minimal suffering.
These include requirements, for example, to have certain types of firearms, and many types of firearms have been banned because they wouldn't make an effective, immediate killing and might result in animals being wounded and getting away in a wounded state. There's been the ban of the killing of whitecoats. There have been measures around humane killing that included making sure the animal is dead before any skinning or processing of it occurs. That includes making sure the skull is crushed so that there is no life left.
There are other measures, such as training individuals engaged in the harvest. On top of that, there's been a significant amount of reaction and mitigative action taken by the sealing industry to make sure that only professional sealers are engaged, and a significant amount of activity engaged in by the Department of Fisheries and Oceans to make sure that the seal harvest is effectively monitored and that when there is harvesting activity, it is conducted in a humane manner.
