A success in protecting animals The Chinese white dolphin is a lovely animal living in the sea along China’s southern coast. Years ago, it was in great danger. Sea pollution and fishing made them lose their homes and food. To save them, our government has made great efforts over the years. Many sea protected areas have been created. People make rules to stop harmful fishing. Local people also help protect the sea environment. Because of these actions, the number of Chinese white dolphins is growing slowly. More dolphins can enjoy a safer life in the sea. From this success, I learn that if humans take action, we can make a real difference to wild‑animal protection. 13 Analyzing your drafts according to the following evaluation criteria.
