Granta Beaches are fragile ecosystems; what starts on one stretch continues along another. Over the years, the erosion has crept up the coast, eating away at the shoreline, swallowing the homes and boats of fishermen. The sandbars that used to absorb the shock of waves far out in the ocean have been flattened. When the tsunami hit , there was nothing to stop the surge of water. Hundreds of villagers lost their lives, and thousands more their homes.
