Many have heard of shark fin soup. But do you realize that you're killing a whole shark each time you enjoy a bowl of shark fin soup?
When people catch sharks, they cut off their fins and throw the sharks back into the ocean. 1
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. 2 Many believe that sharks can never be endangered because they are the strongest in their food chain. 3 The number of some kinds of sharks has fallen by over 90 per cent in the last 20 to 30 years.
Environmental protection groups around the world, such as WildAid and the WWF, are teaching the public about “finning”. 4 So far, no scientific studies have shown that shark fins are good for health, so why eat them? 5

D. But in fact, around 70 million sharks are caught and traded in this industry every year.
E. If the number of them drops too low, there will be danger to all ocean life.
