"A quixotic historian tries to hold oil and gas companies responsible for Louisiana’s disappearing coast."

"In Louisiana, the most common way to visualize the state’s existential crisis is through the metaphor of football fields. The formulation, repeated in nearly every local newspaper article about the subject, goes like this: Each hour, Louisiana loses about a football field’s worth of land. Each day, the state loses nearly the accumulated acreage of every football stadium in the N.F.L. Were this rate of land loss applied to New York, Central Park would disappear in a month. Manhattan would vanish within a year and a half. The last of Brooklyn would dissolve four years later. New Yorkers would notice this kind of land loss. The world would notice this kind of land loss. But the hemorrhaging of Louisiana’s coastal wetlands has gone largely unremarked upon beyond state borders. This is surprising, because the wetlands, apart from their unique ecological significance and astounding beauty, buffer the impact of hurricanes that threaten not just New Orleans but also the port of South Louisiana, the nation’s largest; just under 10 percent of the country’s oil reserves; a quarter of its natural-gas supply; a fifth of its oil-refining capacity; and the gateway to its internal waterway system. The attenuation of Louisiana, like any environmental disaster carried beyond a certain point, is a national-security threat."
