斐济村民变身海洋监测员，每天守护珊瑚礁
In Fiji, a small island country in the Pacific Ocean, some villagers are now scientists. They are called 'reef monitors.' Every morning, they put on a mask and fins. Then they swim in the warm, clear water. They look at the coral—small, colorful animals that make a home for fish.
The reef monitors count the fish. They see if the coral is healthy or sick. Sometimes the water gets too warm. Then the coral turns white. That is bad. The monitors write everything in a notebook. They take pictures with a special underwater camera.
