A beach park is experiencing coastal erosion. Some want to protect the park, including a restaurant, parking lots, an outhouse, and a lawn at any cost; they don’t want to lose a blade of grass. That would require a hard solution, such as a sea wall. Others want to maintain the sand beach and use a more flexible approach to erosion. They argue for beach nourishment and planned retreat. Both groups have clearly stated their values. What are the pros and cons of each position?
