　　答案：　D

　　The pressure to feed Asia's growing population has led to dangerous levels of overfishing near Pacific coastlines.

　　An example can be found in Sindangan，a fishing town in the southern Philippines.The area's once healthy fishing is in danger because of an increase in the number of fishing boats.

　　Across the South China Sea，fish catches near shore have dropped since the 1980s.That drop has pushed fishermen to go offshore with bigger boats.

Benjamin Francisco，an official with the United Nations Food and Agriculture Organization，says some of the methods they use to increase their catches are harmful.These methods harm the ability of some species to reproduce.The fish watcher in Sindangan，Julie Buot，says most of the local fishermen use fine__mesh_nets.Such nets have been banned for years because they catch very young fish.
