One possible version Sharks in Danger Sharks live in the sea. They eat small animals. There were many sharks in the sea before. But now they are in danger. Do you know why? First，marine pollution is very serious，so it's very hard for sharks to live in the sea. Second，people kill sharks for their fins. Every year people kill lots of sharks in the world. The situation is getting worse. We must do something to protect them. To protect animals is to protect ourselves. We should make the sea clean and stop killing sharks. The government should make laws to protect sharks. It's also a good idea to raise public awareness of protecting sharks. Please take action now.
