The sun rose over a swamp near Jean Lafitte, #Louisiana, as @misterwidmer took this photo of cypress trees last month. Saltwater intrusion, the result of subsidence, sea-level rise and erosion, has killed off the live oaks and bald cypress along Louisiana's coast. The @usgs predicts that the state’s wetlands could be gone in 200 years. In addition to the effects of climate change, human engineering has contributed broadly to the losses. Since the early 18th century, the construction of levees on the Mississippi River and the closing of its distributaries have altered natural hydrology and stifled land-building silt deposits from spring floods. Property owners and government regulators have allowed the degradation of swamp and marshland, first for farming and cypress-logging and then, more insatiably, for oil and natural gas exploration. What’s next? For a community like Jean Lafitte, the question is less whether it will succumb to the sea than when.
