largest in the world, and covers areas of the India and Bangladesh for more
than 80 kilometers in forming Sundarbans National park, declared a World
Heritage Site by Unesco. A third of this area is covered by water and marshes,
as well Sundarbanns since 1966 has been considered a sanctuary for wildlife
because it is estimated that there live about 400 Royal Bengal Tigres and more
than 30,000 deer in this area.
