summary

Hurricane Katrina had the most devastating impact on Louisiana where it damages the wetlands. The vegetation might not grow back and the vegetation along water sources disappeared. Whatever remains that were left turned brown. Katrina affected local sea harvests and deceased oysters by two-thirds. US increased imported oysters and fishermen who depended on the oyster industries were unemployed and unsettled. Floodwater was contaminated by household chemicals and affected underground gas and oil tanks. Human corpses and dead pets also increased the risk of bacterial contamination. Dredged materials for platform for the plants to grow on were placed and the Louisiana Coastal Area Ecosystem Restoration Plan plans to rebuild barrier islands and replant lost marsh grass.
