SINGAPORE — “For seven thousand years, Singapore has changed around these reefs,” says Debby Ng, a Singaporean biologist who studies the city-state’s shrinking coastal and marine habitats. “They are still here.” Despite colonization, war, shipping and industrialization, reefs a few kilometers south of Singapore’s gleaming shoreline have endured. “It would be a tragedy if we were to lose them now — in peacetime, at the height of our prosperity, when we possess more knowledge and capacity to protect them than any generation before us,” Ng tells Mongabay.

No timeline for the western island project was given. Wong said reclamation would take place “over the coming decades” and that plans were being studied carefully. But the announcement has alarmed Singapore’s marine conservation community, which says the project could affect some of the country’s most biodiverse waters. The islands include Pulau Semakau, which houses Singapore’s offshore landfill, and Pulau Bukom, home to an oil refinery, as well as Pulau Sudong and smaller islands including Pulau Hantu, Pulau Jong and Pulau Sebarok. The area is estimated to contain some 590 hectares (1,460 acres) of coral reefs — about 60% of the total in Singapore — along with 22% of the city-state’s seagrass meadows and 5% of its mangroves.
