honesty, i have to admit I tried of shark meat few times, curry or deep fry is good, which i treated as another kind of fish. But no shark fin because, to me personally, that's a truely waste of life. Impotence????? I guess not more shark meat for me

John... for the good of my willy, I better dont take my chance ...
If i recall the another study correctly, all the big fish, or should i say predictor fish, contain high level of heavy metal due to polution. therefore, to my opinion, Conservation of diversity, should not limit to protection, but most importantly, limit our polution thru recycling & reduction use of resouces. Big topic. Go and watch the movie "the inconvenient truth" or simply "the simpson movie".
Haha shafi, how ironic.... Glad you are doing your big part. All the best to you
No shark fin, no waste of life.
