Louisiana is sinking.
Researchers have known for years that the swampy land under south Louisiana is sinking (potholed streets and wobbly porches and floors are visible evidence of that) but a lateral movement of the land into the Gulf enters largely unstudied terrain.

Flood protection planners have their work cut out for them as they choose between often competing theories about what is causing Louisiana to lose land at alarming rates. Since the 1930s, more than 2,000 square miles of coast sank or eroded.

Some scientists believe oil and natural gas extraction in the middle and late 20th century caused much of the sinking; others say the land is caving in because the Mississippi River and other waterways were straightjacketed by levees, which stopped floodwaters from replenishing the soil.
Sure, blame the oil companies. There's 100 things wrong with what's going on in Southern Louisiana. Oil companies don't even make the top ten.
