Forest fires in Indonesian Borneo and Sumatra are burning through habitats critical to the critically endangered Bornean orangutan, affecting over half the population across 13 of the 20 largest remaining groups. The fires have also spread smoke to Malaysia and Singapore, indicating regional air quality impacts. The IUCN report underscores an ongoing environmental crisis with biodiversity and transboundary pollution implications.
