Indonesia’s coral reefs(珊瑚礁) are in trouble. Coral mining, Industrial pollution and poisonous agricultural runoff all play a role in their destruction, but the fishermen have been the worst offenders. They not only bomb fish but also poison them with cyanide, an equally destructive practice. The fishermen are also among the biggest potential victims(受害者). Two thirds of Indonesia’s 7, 000 coastal villages are close to coral reefs and thus depend for their livelihood on the harvest of reef fish. The disappearing reefs are already leading to a dramatic decline in the productivity of coastal fisheries and to increasing fights among fishermen.
Indonesia’s reefs are vast – they cover 51, 000 square kilometers, surround 17, 500 islands and stretch 3,500 kilometers – but they are not infinite. Many foreign experts and Indonesians fear that the region’s entire marine environment could be seriously damaged if the reefs keep dying at their present rate. “The overall picture is depressing,” says Ian Dutton, Indonesian director of an environmental group.
Depressing, but not hopeless. Despite the destruction, environmentalists have in recent years made significant progress in changing the hearts and minds of the fishermen. Working closely with local Indonesian authorities in North Sulawesi and less populated eastern Indonesia, where most of the country’s reefs are located, they have succeeded in preventing destructive fishing practices and coral mining from overwhelming the reefs.
Increasing numbers of fishermen are waking up to the threat and protecting the life-sustaining coral before it’s too late. Nuhung, a 56-year-old fisherman, says, “I always knew blast fishing was harmful. Then I suddenly realized that by bombing the reefs I was destroying not only my own but my children’s future.”
