Award-winning writer and lifelong angler Paul Greenberg discusses how large-scale commercial fishing, extensive fish farming, and questionable environmental standards have distressed aquatic ecosystems, pushing many wild fish populations to the brink of extinction.
His new book, Four Fish, focuses on the relationship humans have with salmon, bass, cod, and tuna. Greenberg travels around the globe, from fjords in Norway to massive fish farms in Vietnam, to reveal the history and status of these species. Along the way he discovers that these fish are not the healthiest or the most cost-effective forms of ocean protein, and that our quest for them is unsustainable.
