The growth of the oil industry beginning in the 19-teens meant the digging of canals, dredging of bayous, and building of levees, all of which prevented the deposition of silt from the Mississippi River. Without it, there was no way to replenish marsh land lost to natural compaction. Even more consequential was the continued extraction of oil and natural gas, which caused still more subsidence. On top of everything, global warming – which has recently accelerated — led to sea level rise, stronger hurricanes, and bigger storm surges. The elevation of Isle de Jean Charles, now just two feet above sea-level, is sinking 0.5 inches per year. Formerly 22,000 acres, the settlement is now 320 acres. Within a generation or less, Isle de Jean Charles will disappear, like Atlantis, beneath the waves.
