The mass killing or a naturally-occurring species in it's natural habitat is arrogant to say the least. The way it is done with the harp seal is also barbaric.

The Greenpeace activists, Bob Hunter, Watson and others, are jerks who enjoy the thrill of harrassing people, bullying them and even causing their death. Put them in prison.

If people want to harvest the harp seal, figure a way to raise and feed them at grower's expense, and keep the new "farms" as far away from the native habitat as possible. Perhaps Antarctic waters.

If the naturally-occurring population is destroying it's habitat, proof of that should come from scientists, not Enviromental activists, politicos or from people who are motivated by money.

Move the excess population to the extreme ends of the range and help them become established there. That is being done with many species.
