err.. are you now saying selling and purchasing sharks at wetmarket isnt right as well?
good grief.. i hate amateur yet trying to talk big activist that don't bother to do research and relies on CNN/FACEBOOK for their information. did you know 45% of the things they show on CNN is NOT TRUE? especially when it comes to overseas news? and facebook is even worse.. samore going around shooting people at a personal level.. seriously bro.. you need to control your EQ before you get a heartattack..

sigh.. do i really have to spell everything out to you? or even spoon feed you? here's some REAL facts..
how do they catch sharks? true, some goes underwater with a net and catches sharks (bamboo, nurse sharks), and i saw sharks stranded in the net (i guess the one that caught the shark dropped the net or something, which i set loose) but those are for the illegal purpose of putting them in fish tanks, not our stomach.
the sharks were caught in trawl nets dude.. trawl nets have no eyes. they just catches whatever swim past them.
SOOO.. if you want to stop sharks fin soup, stop the usage of trawl net, which kills mola-molas, whales, dolphines, turtles, sea snakes..
it is good you are energetic and have concern on the environment, but do the right thing.. put your energy into things that will actually work. they have already came out with substitute shark fin.. now we just have to stop catching sharks, which most of the time is accidental. you dont see sharks being sold DAILY at the wet market.. occasionally yes, not everyday like kembung, tilapia etc..
if you cant join the REAL activist, at least support them like what i do. i donate to green peace and signs their petitions. their causes are REAL and they really do research before they go all out. those are activist which deserves RESPECT and not others that go around making noise.
on a personal level, what does being a diver or not have to do with all this? are divers that love spear fishing not divers? are divers that catch clown fish etc.. to be put in tanks not divers? are divers that love harassing fishes underwater, touching them, scaring the shit out of them not divers?
