Peter Neill, director of the World Ocean Observatory, will give an illustrated talk on the oceans and his new book, “The Once and Future Ocean: Notes Toward a New Hydraulic Society,” Tuesday, July 12, at 7 p.m. at the downtown Camden Public Library.

The old paradigm of unlimited growth based on consumption, driven by fossil fuels, is exhausted and on the verge of collapse, Neill writes, and he offers several reasons why water holds the key to humankind’s survival. Water covers 70 percent of the Earth. It also contains a wealth of resources … and it can drive the economy.

“The ocean is where we must turn for fresh water, food, energy, health, political stability, transportation, community development, and personal renaissance,” he said.

The World Ocean Observatory is a web-based place of exchange for information and education about the health of the ocean. Neill previously served 20 years as president of the South Street Seaport Museum, New York; is co-founder of The Sound School and The Harbor School; and has dedicated his career to marine affairs. In addition to “The Once and Future Ocean,” he has written and published numerous works of fiction and nonfiction. He lives in Downeast Maine.
