What Can Be Done About Eroding Coastlines?

"Orrin Pilkey, who directs the Program for the Study of Developed Shorelines at Duke University, believes that in many cases it would actually be cheaper to move buildings back from the water's edge than to fund 10 to 20 years of constant beach replenishment, but his ideas have not had many takers among shoreline communities... Some states and localities in the United States and around the world have "set back requirements," restricting development on the shoreline. Protecting and restoring natural barriers to erosion, like dunes, wetlands, and vegetation close to shore are also natural, low-cost ways to fight erosion."
