The state of Louisiana is in a bad marriage that can only end badly.

From The Nation:

No state in the union has been more firmly wedded to the oil and gas industry than Louisiana. No more zealous preachers of the clean oil gospel can be found than the state’s politicians, who were elected by oil money (at the high end of industry campaign funding) and have defended the industry from regulation (including wetland protections), reduced its royalties with tax breaks and "royalty holidays" (thereby depriving the US Treasury of some $53 billion in revenues from existing offshore leases) and beaten the drums for opening the Atlantic Coast and the Arctic National Wildlife Refuge to oil development… because Louisiana’s experience showed oil and the environment to be so compatible. State brochures feature pelicans and oil platforms against the setting sun. The largest exhibit in New Orleans’s Audubon Aquarium of the Americas contains the base of an oil rig, around which swim contented fish, framed by the logos of Shell, Chevron and BP. We have improved on Eden.

The real story was always otherwise; it was just rarely told. Oil was first found in Louisiana a hundred years ago, and the finds swiftly moved south to the coastal zone. Oil companies appropriated the coastal parishes, most notoriously Plaquemines, ground zero for the BP slick; Texaco’s leases in Plaquemines were arranged by the parish district attorney, who conveniently reported only part of the proceeds to the parish police jury and kept the rest (a fact that is emerging only after his death, in a family feud). Local politicians in their pockets, Texaco et al. had one remaining problem: getting men and equipment to the drill sites and laying pipelines to carry off the gold. In the companies’ way were some 5 million acres of coastal marsh, one of the most biologically productive zones in North America.

The solution was soon to come: floating dredges, which would dig canals to the wellheads and more canals for the pipelines. These dredges have worked nonstop ever since. They have ripped through the wetlands of southern Louisiana like bulldozers, severing bayous, drowning adjacent marshes, draining others and introducing salt water from the Gulf of Mexico that sears the plant roots, at which point they disintegrate and the coastal marsh system, made up of billions of stems and roots of living things, falls apart like wet cardboard. There were alternative means of access, but industry rejected them. It could also have backfilled the canals when the job was done, but this too was rejected. The reasons were remarkably like BP’s: those approaches would take time, cost money.

The dredging was not occasional, or here or there. It was pandemic. The industry has laced 8,000 miles of canals and pipelines through the Louisiana wetlands, each one eroding laterally over time, less an assault at this point than a cancer. They are supported by larger navigation canals, requested by the industry and built by the ever-willing Army Corps of Engineers. One such canal, the Mississippi River Gulf Outlet, after killing off 39,000 acres of forest and wetlands between New Orleans and the gulf, ushered Hurricane Katrina right into the city. If you drive down any bayou road in southern Louisiana, you will see marsh grasses out the window. If you fly over them in a plane and look down, you see something that looks like northern New Jersey: water roads and open water through isolated patches of green. The next time you fly over, there will be even less green. We have been losing twenty-five square miles of coastal Louisiana every year, in major part to these canals, to serve the oil and gas industry, which has made tidy sums in the bargain. When I last looked, six oil and energy corporations were listed in the world’s top ten.

And there’s more. Consider this:

Louisiana, the state most vulnerable to climate change and sea level rise, leads the charge against EPA regulation of carbon dioxide (letters of opposition from no fewer than four state agencies and the governor, which must be a record) and the president’s climate change bill.

Now the oil comes home.
