The US built nearly 2,000 km of Mississippi River levees to control floods; the barriers cut sediment off from Louisiana wetlands, helping erase about 4,900 sq km of coastal land
- US built nearly 2,000 km of Mississippi River levees to control floodsNearly 2,000 kilometres of levees built along the Mississippi River over the past century helped protect cities and farmland from major floods.
- But the barriers also caused one of North America's most serious ecological losses.
- By cutting coastal estuaries off from vital river sediment, the flood control system has contributed to the loss of about 4,900 square kilometres of Louisiana's coastal land since the 1930s.
