When people catch sharks, they cut off their fins and throw the shark back into the ocean. Without a fin, a shark can no longer swim and slowly dies. This method is not only cruel, but also harmful to the environment. 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.
