English summary 2

Hurricane Katrina had the most devastating impact on Louisiana where it damaged most of the wetlands. Thus it is, unlikely that the vegetation in the marshes may grow back. Vegetation along water sources has also disappeared. Those that are remaining have turn into unhealthy brown shade. Katrina took a devastating toll on the local sea harvests; even two-thirds of Louisiana's oysters may have been destroyed. US had to resort to increase the oyster imports from other countries. Thousands of fishermen who depended on the oyster industry find themselves to be unemployed and unsettled. Floodwater in the city became contaminated household chemicals petroleum, disturbed underground gas and oil tanks. Leaking sewer and gas pipes further contaminated the floodwater, human corpses and dead pets further raised the risk of bacterial contamination. Placing dredged material for a platform for the plants to grow on, the Louisiana Coastal Area Ecosystem Restoration Plan is also planning to rebuild barrier islands. Hence, replant lost marsh grass.
