Coastal Restoration in Louisiana Essay -- Environmental Management

Geologically speaking, Louisiana is a very young state. Environmentally speaking, Louisiana is a very fragile state. Louisiana has always been dependent upon the nutrient rich deposits from the Mississippi River to build up the land. Centuries ago the Mississippi River periodically changed its course, building up Louisiana one delta at a time. The erosional forces of the Gulf of Mexico and annual hurricanes depleted Louisiana’s coastline, but the mighty Mississippi River would replenish the land losses. Such is the relationship that forces of nature have with one another. Place mankind in the mix, and the relationship becomes stressed and dysfunctional. The present day Louisiana coastline is a mere shadow of its former self. Let’s look at how Louisiana came to its current demise and what is being done to rectify the situation. Historical Data As sea level rose and fell over Louisiana in previous centuries, the Mississippi River carried large loads of sediment to the Gulf Coastal area from the core of the North American continent and deposited it on the rim of the Gulf of Mexico. Prior to the twentieth century, 5 million acres of land were compliments of the large influxes of mud from the river’s mammoth basin, extending from Montana to New York State. Organic matter from highly productive marine waters has been deeply buried under the whole state and far offshore, turning into petroleum. During other dry periods, large beds of salt were laid down through evaporation. Human engineering has temporarily tamed the river, most of the time, preventing it from dumping its valuable land building sediment all over the place. As a result, coastal Louisiana is sinking out of sight, starved of fresh material. The Mississippi Delta was... ... University of New Orleans. "That's not even possible. The goal is to restore healthy natural processes, then live with what you get." (Bourne) Sounds like a good attitude to this happy Cajun. Works Cited Alden, Andrew. About.com Guide. 4 December 2010 .
