Wetlands are low areas that are sometimes, or always soaked with water, like a marsh or swamp.
They are found on every continent except Antarctica, and in all temperatures, from hot to cold. From the Cajuns of Louisiana, to the Marsh Arabs of southern Iraq, people all over the world have learned to live and work in wetlands. Salt marshes in northern Europe and the British Isles, and later in New England, were used for feeding cattle and sheep, and for growing hay. For hundreds of years, Russian and Irish people have used peat to burn in their fires. Peat is like oily straw and grass that grows in wetlands.
