Many have heard of shark fin soup. This famous and expensive dish is (especial) popular in (south) China. 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 shark back into the ocean. This is not only cruel but also harmful 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' ecosystem. If their numbers drop too low, it will bring danger to all ocean life. Many believe that sharks can never (endanger) because they are (strong) in their food chain. But in fact, around 70 (million) sharks are caught and traded in this industry every year. The numbers of some kinds of sharks (fall) by over 90 percent in the last 20 to 30 years.
Environmental protection groups around the world, such as Wild Aid and the W W F, are (teach) the public about "fin". They have even asked governments ( develop) laws to stop the sale of shark fins. So far, no scientific studies have shown that shark fins are good for health, so why eat (they)? Help save the sharks!
