Some time back I asked him what he was reading. His reply:
The future history of our species will be profoundly affected by what we do or do not do to our planet's seas. Two great and most timely books that can offer us guidance are Paul Greenberg's Four Fish: The Future of the Last Wild Food and Sylvia Earle's The World Is Blue: How Our Fate and The Ocean's Are One.Visit H. Bruce Franklin's website.
For some very different insights into the intricate relations between our species and some fish that might seem most alien, read James Prosek's Eels: An Exploration ... of the World's Most Amazing and Mysterious Fish.
