The real problem here is that people just aren't logical - if they were they wouldn't spend one single minute trying to kill the apparent tourism goldmine that is your average cetacean. There are entrenched interests that want to kill whales in the whaling countries, and they have outsized political influence. The only hope is that if we repeat the logical arguments often enough public opinion in whaling countries will turn decisively against whaling. As I've noted before, Australians love their whales, and so you won't see the Australian government dare to make any pro-whaling decisions, $2.1 billion dollars or not. To do so would be political suicide. The Big Money post notes that whale watching is growing fastest in Japan. Maybe all we need now is a study showing conclusively that whaling activities make whales avoid ships - some anecdotal evidence suggests that species that are no longer hunted become friendly towards humans. Once the Japanese public comes down with a collective case of whale fever, they might convince their government to adopt an emotionally based but economically beneficial policy of whale protection.
After all, how much would you pay for this?
