In the third and last episode, the giant river, which has started its journey as the Yarlung-Tsangpo in the icy heights of the Himalayas, journeys to its end in the Indian Ocean. In the lowlands of Bangladesh, fed by the two more giant rivers, Ganges and Meghna, it finally creates the biggest coast delta on earth as well as the Sundarbans, the world’s most species-rich mangrove forest. This episode celebrates its world premiere at the Mountain Film Festival Graz.
