Not so long ago, the world’s oceans were filled with different types of fish. Now, a large increase in global overfishing has threatened that supply. According to the United Nations Food and Agriculture Organization, 90 percent of the world’s fisheries are either being fully exploited, or are at risk of collapsing. With fish supplies running out closer to home, fishermen are traveling further and further to find their catch. Frequently, fishermen are crossing over into other countries’ territories, creating both political and environmental conflict. Overfishing can be found everywhere, from Mexican fishing boats off the U.S. coast of Florida to Russian crabbing boats in the western Bering Sea. However, the impact is felt the strongest in the South China Sea, where many countries have territorial claims.
