Bangladesh's problem, like Lord Shiva's hair, has many strands. All three of its great rivers rise in the Himalayas, from which they carry a huge load of sediment, made worse in recent years by the deforestation of the Himalayan foothills. Because Bangladesh is as flat as a pool table, most of it no more than a few feet above sea level, the flow of its rivers is sluggish. Riverbeds clog with silt and water levels rise; shorelines erode, swallowing up farmland; islands of sand and mud form, disperse, reform elsewhere. From May to November, the monsoons blanket the country with torrential rain, pushing the rivers over their banks, driving people from their homes, drowning them.
