Singapore is experiencing its worst haze of the season, with air quality reaching unhealthy levels across the country. The National Environment Agency attributes the pollution to transboundary smoke from hotspots in Indonesia.
Why it matters
Severe air pollution poses significant public health risks and highlights the ongoing regional challenge of transboundary haze in Southeast Asia.
