44% of Singapore's corals affected by bleaching, with an estimated 5% dead
About 44% of Singapore's corals have undergone bleaching, with an estimated 5% dead. Corals, which are made up of small animals called polyps, host tiny algae that feed it and give it colour. When stressed by rising temperatures or pollution, corals expel the algae, losing their main food source and leaving a ghostly white husk behind. Singapore experienced major bleaching events in 1998, 2010, 2016 and 2024, as a result of unprecedented marine heatwaves. Caitlin Ng takes a look at the factors that affect recovery and what's being done to protect Singapore's coral reefs.
