The introduction of predators has already been done in the past to control other populations, and the evidence shows that it's not usually a good idea. The idea of sterilization campaigns was also floated, but at the moment, humans are short of proteins. So if the reduction of a particular species' population is desired, it would be ridiculous not to hunt it in order to use it. That, we feel, would be wasteful. If you're going to reduce the seal population, you might as well do so in a way that benefits from the protein and everything else that can be used to good effect, given that all parts of the animal are recoverable, including by-products.
We are therefore in favour of a hunt. Why not avail ourselves of being able to use the resource rather than waste energy to sterilize seals? It would amount to a straightforward loss of energy and funds, when it could otherwise be used to feed people and supply protein or other value-added items. As for the introduction of a predator…
