Environmental Economics

Here is one last picture from my vacation. I built this sand castle using everything I knew about coastal engineering. In the right hand side of the picture you can see the last structure left standing from what used to be a proud, but poor, coastal town. Alas, it could not afford protection against high tide. The more affluent community has a moat, a seawall (with an ingenious gap that allows water to come through, avoiding the full force of the waves) and another moat that first breaks the force from the waves. This affluent community was built to last!
