<p> We always think sharks are the most strongest and never be endangered because they are at the top of the food chain in the ocean's ecosystem. But in fact,their numbers drop low,around 70million shares are caught and traded every year. They are cut off fins and then are thrown back into the ocean. Without fins,they can no longer swim and slowly die. </p><p> Why do people do that? They just want to make shark fin soup which are famous and expensive especially in southern China.a Therefore each time you enjoy a bowl of shark fin soup may mean you are killing a whole shark. </p><p> People'cruel action is harmful to the environment. On the one hand it will bring danger to all ocean life,on the other hand it will cause water pollution. So environmental protection groups around the world,such as WildAid and the WWF ,are teaching the public about"finning".They have even asked governments to develop laws to stop the sale of shark fins.</p><p> No trading,no killing. Please stop drinking shark fin soup. Help save the sharks together!</p><p> </p>
