Once, Læsø Island off the coast of Denmark was home to a thriving salt industry. So successful was the industry that all the island’s trees were chopped down to feed the salt kilns. Then the salt industry collapsed, without wood for the kilns. With no trees left to break the wind, Læsø’s villages were buried in sandstorms. The air became full of sea salt. The salt inhibited the growth of any kind of plants, even grass. Læsø, however, had plenty of eelgrass and driftwood. So the people began using driftwood to build their houses and the eelgrass was used for the roof. This small island is the only known place where seaweed is used for roofing!
