re: Louisiana Coastal Erosion.

A) I think hydrocarbon extraction and canal excavation is a contributing factor, but it's not the main factor in land loss, faulting and deep subsidence is.

B) the state is designing large scale diversions to mimick wax lake's flow and magnitude. It can be done, but the fishing industry will tie it up in court for decades until they are paid off or exhausted of legal avenues. By that time, our problems will have compounded.

C) the fishing industry, between legacy lawsuits, oil and gas activity settlements, natural disasters, oyster ground subleasing for 1000% markups, and oil spill have become so accustomed to receiving 'supplemental income' that sometimes I wonder if the actual harvest is profitable anymore.

D) there is no going back to a 1900s coastline. We must reengineer it to actually build land or maintain what we have. This means calculated retreat and relocation of humans, their assets, and the places they are accustomed to harvesting resources. Louisiana's coastline has fluctuated for tens of thousands of years and the public perceives that it should be a static entity. Humans have lived along this coastline since before the pyramids were built and have constantly shifted and adapted.
