To be fair Nick your statement, "They do what is needed to achieve their environmentalist goals...," is a patent statement of terrorist. The results do not usually justify the means. I would agree that the practices need to be examined and curtailed, but that could take away freedoms and erase culture & custom, much like Europeans did to the Native Americans. So how would that be better than killing off the whales, tuna, or any other species? My point is that there are better and legal ways to seek and incentivize change. Destruction is not an incentive, nor a true deterrent. Destruction often leads to entrenching of ideas, ideals, and actions.
I find that if someone has a problem, before they express it loudly they should have a workable solution. A few suggestions for curtailing the whaling, overfishing:
1. Make people fish for themselves, by putting huge restrictions on catch numbers.
2. Put huge impact taxes on large hauls, based on boat, captain, and/or parent company.
3. Turn aquariums into fisheries, but still allow people to come see ad learn about what is going on. (A touch of jest here)
4. Give people more vacation time to do their own fishing. (A touch more of jest here)
