You can go on and on with your flimsy defense of the practice,you must really enjoy the stuff but the bottom line here is that the animals are being decimated with no regard to population levels.There is a supermarket in my area that has piles of beheaded sharks with all the fins ripped off,I dont know which species these were,they could have been captured locally and these types of markets are all up and down the coast and on the west and they all more than likely carry the sharks in this condition.So that whole thing about catching the fish and using most of the body does not float,the fish does not reproduce at a rate to keep up with the ammount that is being wiped out,farm raising sharks is not an option,soo they will be fished and hunted untill there are no more sharks left all for the sake of a menu item,either you dont care enough about it or you must look forward to this outcome.Maybe they should use your ears.
