Environmental Effects of Hurricane Katrina:
On August 29, 2005, Hurricane Katrina hit New Orleans as a Category 3 hurricane on the Saffir-Simpson Hurricane Scale with winds up to one-hundred and forty miles per hour. Katrina was one of the costliest and deadliest hurricanes to ever hit the United States. One-thousand eight hundred deaths, seven hundred missing and one-million displaced is evidence of the human toll that Katrina caused and $84 billion in cost makes Katrina the most expensive natural disaster in United States history. (Blackwell) While these numbers are devastating, the environmental impacts of Katrina still threaten the citizens of New Orleans today. The environmental impacts from Katrina were compounded by man-made environmental hazards. (West)
Due to an above average level of poverty, many homes in New Orleans had very high levels of lead and arsenic in them. (Pastor) This combined with eighty percent of the city being flooded, released significant amounts of lead and arsenic into the environment which still exist today. Soil samples taken before and after Katrina showed elevated levels of lead, iron and arsenic. (Reible)A new study on one-hundred and nine households found that sixty-one percent had lead measurements above federal standards with twenty-seven percent greater than one-thousand two hundred ppm which was significantly higher than the five-hundred and sixty ppm collected before Hurricane Katrina. (Rabito) These inorganic compounds are related to cancer risks of which New Orleans already has a significant problem with. This complicates the decision on when and where to conduct environmental clean-ups in New Orleans to remove the lead, iron and arsenic.
In addition to these problems in houses, New O...

...e miles per year prior to Hurricane Katrina and the levee breaks increased this. The wetlands were already being affected by oil and gas development, rising sea levels, and an invasion by an aggressive beaver like rodent called the nutrias. (Rastogi)
Katina had significant negative environmental impacts on New Orleans. The extent of the impacts is still unknown and continues to cause a risk to the population of New Orleans. The environmental and health impacts of Katrina will be severe and long-term. The effect of long-term exposure to contaminate by New Orleans citizens is still uncertain. Because of this uncertainty the public nor the local government will not delay rebuilding the city. This posses questions on whether people with delay their return to New Orleans and what the effect of contamination would be on them and their children in the long-term. (Reible)

    Donald Worster introduces a framework for analyzing environmental history along the three dimensions of culture, social organization, and nature, which can be used to investigate how the ‘levees only’ approach to managing the waters of the Mississippi River set the scene for the disastrous effects of Hurricane Katrina in New Orleans, Louisiana (4-5). The ‘levees only’ approach grew from and promoted certain cultural, social, and natural conditions in New Orleans, and each of these elements critically interacted to contribute to the human and environmental destruction unleashed by Katrina. Cultural, social, and natural elements of Worster’s framework individually shaped the essential preconditions of the Katrina disaster. Culturally, New Orleans’s

    ...n, the Louisiana wetlands are an extremely valuable asset to the State of Louisiana and the United States. The continual loss of Louisiana wetlands has the potential to have an immensely negative effect on the economy at a state and national level. Over 2 million people live in the Louisiana coastal parishes (Field et al., 1991). The majority of people living on the Louisiana coast make their living from things that are directly related to the wetlands. The Louisiana wetlands make up the largest wetland community in America and is being lost at a rate greater than the other wetland communities in the country. The suggested strategies that are being taken into consideration could be helpful but it seems that the State of Louisiana is not as concerned as it should be given the future consequences and much like climate change coastal erosion is not being taken serious.

    In the late summer of 2005, a terrible tragedy occurred that changed the lives of many in the south-east region of the United States. A Category 3, named storm, named Hurricane Katrina, hit the Gulf Coast on the 29th of August and led to the death of 1,836 and millions of dollars’ worth of damage (Waple 2005). The majority of the damage occurred in New Orleans, Louisiana. Waple writes in her article that winds “gusted over 100 mph in New Orleans, just west of the eye” (Waple 2005). Not only was the majority of the damage due to the direct catastrophes of the storm but also city’s levees could no longer hold thus breaking and releasing great masses of water. Approximately, 80% of the city was submerged at sea level. Despite the vast amount of damage and danger all throughout the city, officials claimed that there was work being done to restore the city of New Orleans as a whole but many parts, and even the people, of the city were overlooked while areas of the city with higher economic value, and more tourist traffic, were prioritized along with those individuals.

    On August 29th, 2005, Hurricane Katrina, the most expensive hurricane in American history, made landfall in Louisiana with winds of one hundred and twenty-seven miles per hour (“Hurricane Katrina Statistics Fast Facts”). The sheer magnitude of the amount of lives and property lost was enormous, and it was triggered simply by warm ocean waters near the Bahamas ("How Hurricane Katrina Formed"). Nature was indifferent to whether the raging winds and rain would die off in the ocean or wipe out cities; it only follows the rules of physics. A multitude of American authors has attempted to give accounts and interpretations of their encounters with the disinterested machine that is nature. Two authors, Stephen Crane and Henry David Thoreau, had rather contrasting and conflicting interpretations of their own interactions with nature.

    On August 29, 2005, the third strongest and biggest hurricane ever recorded in American history hit the Gulf Coast at eight o’clock a.m. The interaction between a tropical depression and a tropical wave created a tropical storm later referred to as Hurricane Katrina (FAQS, 2013). Forming over the Bahamas, Hurricane Katrina gradually strengthened as it moved closer and closer to the Gulf of Mexico. Recorded on August 28th, 2005, Katrina jumped from a category three storm to a category five storm with maximum sustained winds up to 160 miles per hour. Although other hurricanes, such as Hurricane Rita and Hurricane Wilma, exceeded Katrina, this dominant storm was classified as the fourth most intense hurricane based its pressure capacity. Once Hurricane Katrina hit land, it was pronounced as a category four storm moving slowly. While people thought that the slow speed of this storm prevented trauma, records show that Katrina did more damage than any fast-moving storm could have ever achieved (Solanki, 2013). Katrina produced abundant debris. The debris was in such large quantity that if it was stacked together on a football field, the rubble would reach the elevation of ten and a half miles. The size of Katrina also caused 90,000 square miles to be affected. Once proclaimed a category three storm, Hurricane Katrina slowed to the speed of 155 miles per hour. At this point in time, Katrina proved to be the sixth most prevailing hurricane traced in history. (Solanki, 2013). Several different aspects of life were impacted by Hurricane Katrina such as availability of gasoline, economic issues, and the ability to have an adequate supply of drinking water (Solanki, 2013).

    Hurricanes occur all over the world, at different times, but commonly through June first and late November. However in late August 2005 a catastrophic hurricane struck. This was Hurricane Katrina. With winds traveling over one hundred miles per hour making it a category five on the Saffir- Simpson Hurricane Scale it was said to have cause billions of dollars’ worth of damage. Hurricane Katrina flooded nearly forty thousand homes, and killed at least two thousand people (“Hurricane”). An average category five hurricane has enough energy to power street lamps for more than twenty seven thousand hours (Williams 58). Knowing about Hurricane Katrina, and the devastation of the city in New Orleans would be beneficial. Also, general information on hurricanes can help civilians and people of higher authority better understand and prepare for damage that could once hit their town and community. Because experts know the general information on these storms they can help explain to the public why and how Hurricane Katrina and other hurricanes occur. Hopefully, in the future civilians will know and use this information to their advantage against hurricanes.
