Sewer Bed Beach, Nantucket, MA

We are losing this place twice over: first to money, and then to sea. There are ways to quantify these losses: only 3,200 bushels of scallops were caught this past winter and more than $2 billion in real estate transactions were recorded last year. My parents aren’t sure where they should be buried; all the graveyards in all the towns we have ever lived will one day be inundated. I imagine horseshoe crabs trolling along the bottom, pausing to read the names etched on headstones.

All over the island, it looms: this is the end of something. I walk along the dune-tops, what’s left of them, at the very end of South Shore Road. Over one shoulder is the Atlantic; endless. Over the other are the sewer beds. A sandy strip separates the two. Second homes are not the only creatures perched precariously on eroding shorelines. Our wastewater treatment facility hangs in the balance.
