es out by the soil’s own weight, new sediment fails to replenish the loss casing a loss of 4 feet of land at the mouth of Mississippi every 100 years.
8. Thousands of miles of web like navigation canals are responsible for destroying 10% to 30% of the marshes. These canals are also responsible for an unknown percent of land loss because they cut off marshes from natural water flow, opening them up to salt water intrusion and erosion.
9. Salt water from the Gulf moves inland through canals and waterways killing fresh water plants that can’t stand the salt. As the plants die, the soil their roots hold together is eroded away, destroying marshes and wetlands.
12. From 1932 to 2000, Louisiana lost nearly 2,000 square miles of land bringing Gulf of Mexico near to the resident’s backyards. If nothing is done to stop the current situation, geologists predict an additional 7,000 miles of land could disappear by 2020.
13. New Orleans should not be built again. The coast line of New Orleans is very dangerous and it will soon be destroyed again because the city is protected by the levees which contribute to land loss.
21. Hurricane Katrina occurred because some levees in New Orleans were replaced with walls approximately 2 feet thick to widen the canal which fell during the hurricane (Hurricane Katrina Relief, 2010).
22. The nature or Hurricane Katrina changed dramatically from 28 to 29 August. Studies suggest that this change in nature from tropical storm to a category 5 and then back to category 3, is directly associated with the land fall in Louisiana (Richard D. Knabb, 2005).
25. It is said the damage done by Hurricane Katrina could have been avoided. The state was aware of the intensity of the hurricane and should have taken measures to avoid the death of 1,300 people. It is said that the military lacked cooperation with the Homeland Security and other relief agencies (Fox news, 2006).
26. It is not possible to prove that global warming caused Hurricane
