Supplemental Reading: Drowning New Orleans

A Scientific American article published in October 2001 and named "Drowning New Orleans" essentially predicts the large scale impact a giant hurricane would have on the area, years before Hurricane Katrina.

Authorities at LSU's Hurricane Center and Water Resources Research Institute, and US Army Corps of Engineers lead a discussion of how Louisiana's coastal region is doomed to storm surges. A case in point is the deterioration of the Mississippi Delta, a triangular-shaped deposition of sediment, which works to mitigate flooding and damage caused by storm surges. In fact, every four miles of the delta could knock down a storm surge by one foot. Unfortunately, some areas of the delta like Port Fouchon are losing 40 to 50 feet of land per year. By 2090, experts at LSU have postulated that the delta will be gone - vulnerably leaving New Orleans on the sea. Aside from the delta, barrier islands and marshes are the only other two natural entities which could mitigate a storm surge. The barrier islands' black mangrove trees and the marshes' tall grasses interfere with incoming gulf currents. However, just like the Mississippi Delta, these natural entities are also eroding (Fischetti, 2001).

One reason for this erosion is the oil and natural gas business. This industry has built many wellheads out in the Gulf, which transport the mined resources back to the coast through extensive underwater pipeline canals and navigational channels. The intrusive nature of this system requires the removal of land from the delta. An oil and gas industry-funded study found that this industry has removed one-third of the delta-land loss. Another human-induced risk factor was the US Army Corps of Engineer...

...0 billion per year due to an average of 130,000 deaths from this problem (Diamond, 2005). Therefore, the "U.S. Clean Air Act of 1970, although it's cleanup measures do cost money, has yielded estimated net health savings (benefits in excess of costs) of about $1 trillion per year, due to saved lives and reduced health costs" (Diamond, 2005). Saving the environment has far-reaching implications. The improvement of many environmental conditions ultimately helps human health and saves money; a clear case in point being New Orleans. In this case, Washington D.C. should more strongly consider mitigating environmental problems when they arise.
