For Kennedy, who formerly directed both the National Park Service and the National American History Museum, this moral outrage has added saliency due to the terrible effects that plantation slavery had on the land and on the American Indians and yeoman farmers who inhabited it.
The hydrology is so atypical that he and Mitchell believe USGS should establish new protocols for collecting the dataset it uses to portray surface water on maps. As New Orleans grew, Lafitte also became a favorite destination for weekend hunters and anglers.
It took Katrina — and the destruction caused by her less publicized but also ruinous sister, Hurricane Rita—for flood protection to enter mainstream cocktail and dinner conversation, shedding harsher light on the incontrovertible fact that the system built by the United States Army Corps of Engineers was an accessory to its own malfunction.
But even those who Lost in louisiana essay or play in the marshes were misled for decades by the gradual changes in the landscape. South Louisiana has always vexed cartographers. Fishers and other boaters used canals as shortcuts across the wetlands; their wakes also sped shoreline erosion.
His interpretation, however, frequently conflates unforeseen long-term consequences with intentionality in a way that misleads rather than clarifies the developments and decisions he examines.

Meanwhile, global warming is causing seas to rise worldwide. Jonathan, that was supposed to help! Like a sponge pressed against a countertop, the soil compresses as the moisture is squeezed out.

The best evidence of this dependable rhythm of land building and sinking over seven millennia is underground. You have to have a very large scale to render it. Cutting against the interpretation of John C. On a map it appears as if the city sits comfortably inland from the ocean.
The state estimates that roughly 10, miles of canals were dredged to service them, although that only accounts for those covered by permitting systems. Oil and gas removal exacerbates subsidence of land, and the canals the companies have dug through the marsh disrupt the delicate balance of salt and freshwater in wetlands, killing plant and wildlife and causing erosion on the interior swamp and marsh already threatened on the outside by global sea level rise.
In an ecosystem covering thousands of square miles, those losses seemed insignificant. The rest of the country would take notice, forging national agreement on the Master Plan and its funding as the most effective means for averting economic catastrophe.
So, stop and compare the existing boot with ours. Some of the money will come from an increased share of offshore oil and gas royaltiesbut many coastal advocates say the industry should pay a larger share.

Louisiana has lost up to forty square miles of marsh per year for several decades (accounting for 80% of the nation’s annual coastal wetland loss) (mi-centre.com).
From a hydrologic standpoint, the wetlands replenish aquifers, hold excess floodwaters from intense rainfalls, and provide storm surge protection.
