I don't believe their figures.

But if we had of removed that amount of mass you'd expect the continent to rise. Maybe it's fuck all, still want to know the figure -

and obviously the greatest source of land loss is ground water depletion near the sea. We need to replenish aquifers even if studies like these are just made up. And heck we could even raise our land near the sea rather than messing with dikes.
