Japan continues to overfish, yet noone really cares about the plundering fish stocks (some fishermen blame the whales, so that Japan's "research teams" can go and get more of those).
Actually, one of the biggest makers of shark fin soup is... Japan, or so I hear (they ship most of it to China). Although the image of shark fin soup is that of the fins of our favorite apex predators, in fact most of it seems to be taken from benign (but big) sharks like the basking shark. Also note that although it tastes good, the fin itself seems to impart little or no flavor to the dish - mostly texture.
I also agree with Andy's last sentiment there - I have yet to meet any tree-hugging-do-gooders in Asia, but there were droves of those around me in the States (lots of pseudo-hippy girls, especially)... Comparing normal (non-hippy) folks, you can also notice a very large difference in terms of outlook (i.e. in Asia, most people either are apathetic or think that it is an anti-culture conspiracy).
