This week on The Learning Curve, guest co-hosts Charlie Chieppo and Kerry McDonald interview Professor David Abulafia from Cambridge University, who discusses the many roles of the world’s oceans in human history and trade. He focuses on how the Pacific, Indian, and Atlantic oceans, along with the Mediterranean Sea, have networked human societies and spurred the rise of civilizations. From religion, language, and culture to maritime trade, military conflict, and the modern era of container ships, Professor Abulafia shows how the oceans have been instrumental in shaping cultures and history, and outlines the seas' ongoing importance in the century ahead. Professor Abulafia concludes the interview with a reading from his book The Boundless Sea: A Human History of the Oceans.
