Is New Orleans and the Mississippi Delta a microcosm of environmental catastrophe? If you are paid per word, it may be more remunerative to try to describe why it isn’t:
Extensive studies done after Katrina verified what lifelong residents of southeastern Louisiana already knew: Unless the rapidly disappearing wetlands are made healthy again, restoring the natural defense, New Orleans will soon lay naked against the sea (see satellite image, below).
So, how does one reengineer the entire Mississippi River delta—one of the largest in the world—on which New Orleans lies?
Three international engineering and design teams have reached a startling answer: leave the mouth of the Mississippi River to die. Let the badly failing wetlands there completely wither away, becoming open water, so that the upper parts of the delta closer to the city can be saved. The teams, winners of the Changing Course Design Competition, revealed their detailed plans on August 20. Graphics from each plan are below.
Scientists worldwide agree that the delta’s wetlands disintegrated because we humans built long levees—high, continuous ridges of earth covered by grass or rocks—along the entire length of the lower Mississippi River. The leveed river rims the southern boundary of New Orleans and continues another 40 serpentine miles until it reaches the gulf. The levees, erected almost exclusively by the U.S. Army Corps of Engineers, prevented regular floods from harming farms, industries and towns along the river’s course. However those floods also would have supplied the brackish marshes with massive quantities of silt and freshwater, which are necessary for their survival.
Good grief. Emphasis mine because they mean that so literally, when we throw around all kind of colorful euphemisms to describe and debate I guess after a while we return to original meanings again. What the miles of levees have wrought, let now engineering decisions and new diversion structures put asunder. Or let the delta die. May 1,000 new songs be written, though immaculate recordings and an army of busking crooners still won’t dull the pain of the [algal] bloom.

Our best hope for carbon reduction is steep price drops in the cost of generating electricity by wind and solar; in the cost of installing wind turbines and solar panels; and in the cost of storing energy in batteries. If those price drops are achieved, we’ll head toward vast reductions in emissions regardless of what the EPA does. No one is going to pay 12 cents a kilowatt hour for electricity (our current national average) if it can be had for 2 cents a kilowatt hour, all other things being equal.



Like corporate green advertising, our policies against the poor get lost in a shuffle of righteous sounding reforms, intended to move people from “welfare to work” in order to usher in a new era of “personal responsibility.” The two strategies have much in common as we whitewash our consciences with high morals and the appearance of genuine, public-spirited problem solving. But there’s a dark side to this shell game every bit as dastardly as Exxon-Mobile working to build your energy future: Where do the poor go once they leave a statistical column?
