Many areas are simply impossible to protect, such as theBrahmaputravalley in Assam, where one of the mightiest rivers in the world keeps changing its course on its flat flood plain.
England has been intimately connected to this corner of India since 1826, when the British began planting tea estates all along the river valley of the mighty Brahmaputra, which courses out of the Himalayas and flows through Assam on its way to the Indian Ocean.
