The Interview: Paul Greenberg and Four Fish

Paul Greenberg is a journalist, novelist, lifelong fisherman, and the author of Four Fish:  The Future of the Last Wild Food.  His best-selling and important book explains what happens when hunger, the environment, nature, and greed intersect. 

He talked with us about why we're at risk of depleting our seas, the wild versus farmed fish choices that home cooks can make, the meaning of genetically engineered salmon, and how to understand the lives of the fish that we eat.
