What is the Sundarbans National Park and why is it important for both India and Bangladesh?

The Sundarbans National Park is a UNESCO World Heritage Site and the world's largest mangrove forest, shared between India and Bangladesh. Approximately two-thirds lies in Bangladesh whilst the remainder is in India. This unique ecosystem is home to the Bengal tiger and numerous other species. The mangrove forest serves as a natural barrier against cyclones, protecting millions of coastal inhabitants from natural disasters.
