　　People in southern China like famous and expensive dish-shark fin soup，but no scientific studies have shown that shark fins are good for health．So why do they eat them？Do they realize that they’re killing a whole shark each time they enjoy a bowl of shark fin soup？

　　When people catch sharks，they cut off their fins and throw the shark back into the ocean．Thisis not only cruel，but also harmful to the environment．Without a fin，a shark can no longer swim and slowly dies．Sharks are at the top of the food chain in the ocean’s ecosystem．If their numbers drop too low，it will bring danger to all ocean life．In fact，around 70million sharks are caught and traded in this industry every year．The numbers of some kinds of sharks have fallen by over 90percent in the last 20to 30years．Help save the sharks!
