Polders: Land from the Sea Dikes-earthen banks 40% of the Netherlands was once under water Polder-land that is reclaimed by diking and draining

Seaworks Structures that are used to control the sea’s destructive impact on human life Windmills used to power pumps that drained the land

Waterways for Commerce: Venice’s Canals Venice, Italy-120 small islands and part of the mainland The Grand Canal flows between them

150 canals are used Transportation: Boat or walk Became a port city, trade helped city grow

Problems Weight of buildings compressed the land-Venice is gradually sinking Flooding-rising sea levels Water pollution damages foundations
