The Sundarbans, a vast mangrove forest located at the mouth of the Ganges and Brahmaputra rivers, is the largest single-area mangrove forest in the world. Spanning parts of Bangladesh and India, this unique ecosystem serves as a critical natural barrier, protecting inland communities from the fury of cyclones and tsunamis. The dense tangle of roots and branches absorbs the energy of storm surges, reducing the impact on coastal villages. Beyond its protective role, the Sundarbans is a biodiversity hotspot, home to the Royal Bengal Tiger, whose population in this region is among the highest in the world. The forest also supports a variety of migratory birds, crocodiles, and numerous species of fish and crabs. Historically, the area was known for its rich resources, including honey, fish, and timber, which sustained local livelihoods for centuries. However, rising sea levels and human encroachment pose significant threats to this fragile environment. Conservation efforts by governments and NGOs aim to balance the needs of local people with the preservation of this vital habitat. The Sundarbans is not just a forest; it is a lifeline for the coast, demonstrating the intricate link between human survival and the health of natural ecosystems. Protecting it ensures that future generations will continue to benefit from its ecological services. Which of the following is NOT mentioned in the passage as a resource historically obtained from the Sundarbans?
