Protect Wetlands to Cut Flooding

One of the first sounds I learned to imitate as a child was the UNKachunka-UNKachunka of a pile driver, pounding steel pilings into unstable ground before anyone built a new warehouse, medical building, apartment complex or any other major structure near the waterfront in my hometown of Norfolk, Va. It didn't even have to be at the waterfront, since much of the original town was built on wetlands that had been filled in decades and sometimes even centuries before I was born.
