Indonesia is home to one-third of the world's coral reefs, with coral that covers nearly 85,000 square kilometres (33,000 sq mi) and is home to one-quarter of its fish species. Indonesia's coral reefs are located in the heart of the Coral Triangle and have fallen victim to destructive fishing, tourism and bleaching. Data from LIPI in 1998 found that only 7 percent is in excellent condition, 24 percent is in good condition and approximately 69 percent is in poor-to-fair condition. According to one source, Indonesia will lose 70 percent of its coral reef by 2050 if restoration action does not occur.
