passage 1
there are thousands of coral reefs(珊瑚礁) in the world; unfortunately, however, they are now in serious danger. more than one-third are in such bad shape that they could die within ten years. 16 here are the three main causes discovered.
the first cause is pollution on land. the pollutants run with rainwater into rivers and streams, which carry the poisons into the ocean. 17 so they will be easily infected(感染) with diseases.
