Shark's fin soup is a type of soup that people make from the fins of sharks. Sharks are big fish that live in the sea and have a lot of fins.
Some people really like to eat shark's fin soup because they think it's really tasty and special. But this soup is not good for the sharks. People catch the sharks and cut off their fins, which is really mean because the shark needs its fins to swim and live in the water.
After the fins are cut off, the poor sharks are thrown back into the water and can't move properly or breathe well. This is really dangerous for the sharks because they can't swim and hunt for food.
The truth is that we don't really need to eat shark's fin soup because there are so many other delicious foods that we can eat instead. It's important to be kind to animals and not hurt them just for something that we don't really need.
