From your posts it's obvious you don't get out much, so we'll keep this simple for ya.

Coastlines are not all sand. And of those portions that are sand, not all sand is alike. Removing sand from one area to build berms in another creates new problems in the area of removal; navigation, erosion, ecological, etc. Building berms to keep the oil out also keeps the water out. The marshes dry up, ergo, no marsh. What have you accomplished? You've gone from an oil-damaged marsh to a dead dry ex-marsh. Congratulations?

Stick to taking pictures, it'll help us all.
