Actually you are incorrect about the oil industry not causing coastal erosion. Probably the largest factor in coastal erosion in Louisiana have been the loss of marshland. What happenned is that navigation channels were cut through the marshes by the oil industry for better access wells in those marshes. Unfortunately, those channels have led to salt-water intrusion and the death of the marsh plants which hold the soil. Instead of marsh, we have open water.

Good summary.
