I've met Paul Watson on two occasions and he seems an honest fellow. Perhaps I am easily persuaded, but he convinced me that he's doing the right thing, that he has asked to be arrested and that foreign countries refuse to do so. I've met Rob Stuart (Sharkwater) and perhaps he is young and impressionable, but he seems to like Paul Watson after having gone through some pretty hairy moments with him, filming the movie.
The bottom line is that all whaling and shark fishing will end when there are too few of the animals to hunt profitably. Paul Watson has had an emotional connection to animals, including whales, which makes it impossible for him to sit still when he knows there is something that can be done about it. If there are international treaties banning the killing, so much the better, he can feel justified as being an international police officer enforcing international treaties.
Are there better ways to solve the problem? Of course. There is a better way to do anything. The trick is to find it. Until then, people do what they can, and he is really putting himself on the line doing something about something he believes in, and he's never killed or gotten anybody killed, doing it.
Before criticizing the man, of course, ask yourself what you are doing to solve the problem. Eventually there may be no problem to solve because of extinction. Until then, some believe action is required rather than more and more talk.
By the way, movies such as Sharkwater may in fact do a lot more for raising awareness than Paul Watson's activities, but there has to be a combination of awareness (to change behavior and laws) and action. That's why it was so cool to have Watson and Stuart together in the movie.
