In 2014, I circumnavigated the globe by ship in 112 days; sailing in the Pacific, Indian, and Atlantic Oceans, the East and South China Seas, the Andaman Sea, and the Strait of Malacca. This voyage enriched me in many ways, but perhaps most of all by being exposed to the sea—the staggering reality of its expanse, its risky symbiosis with the weather, and the often-sorry interactions betweenhumans and the sea. Now safe at home, I read about the daily loss of life by drowning in the Tyrrhenian Sea, and empathize with the families making the decision to leave one continent and sail to another. How can they ever understand the magnitude of the Seas they are about to cross?  The subsequent sadness combines with my privilege and provides a new context for Sight Lines.
