The Great Barrier Reef in Australia is losing its coral because the ocean water is getting warmer.

For example, rainforests produce oxygen（氧气）and take in carbon dioxide（二氧化碳）. Coral reefs protect coastlines from storms. What can we do? First, we can learn more about natural wonders. Second, we can reduce pollution and waste. Third, we can support（支持）organizations that protect nature. Everyone can make a difference — even small actions can help protect these amazing places for future generations.41. What is happening to the Great Barrier Reef? A. It is getting bigger. B.
