Where is the largest mangrove forest?

The Sundarbans is the largest contiguous mangrove forest on Earth, covering roughly 10,000 square kilometres across the delta where the Ganges, Brahmaputra, and Meghna rivers meet the Bay of Bengal, shared between Bangladesh and India. Its dense, salt-tolerant mangrove trees grow in the tidal zone, with tangled roots that rise above the water. This unique ecosystem shelters an astonishing variety of wildlife, most famously the Bengal tiger, which here has adapted to swimming and hunting in the waterways. Mangroves are vital natural barriers that protect coastlines from cyclones, storm surges, and erosion, and they store large amounts of carbon. The Sundarbans is recognised as a UNESCO World Heritage Site, though it faces threats from rising seas, storms, and human pressure.
