Since I love seafood, I was drawn to Paul Greenbergs Four Fish: The Future of the Last Wild Food. Growing up fishing, Greenberg turns his attention to salmon, bass, cod, and tuna as the four main species dominating the world market in this passionate piece about protecting the future of fish stocks. Greenberg argues we are at a tipping point where intelligent policies can preserve the future of healthy and sustainable seafood or shortsighted ones can doom us to destroy the last wild food on earth. It seemed more like a personal journal of discovery than a systematic review, but he does give an outline of what such policies and practices might look like. It got me thinking about what is our relationship to fish and what we would like it to be. While some of the material is familiar to me, I enjoyed Greenbergs writing style and would recommend it to readers interested in food policy, environmental concerns, and the classic tragedy of the commons problem.
