Paul Greenberg

Salmon are among the precious and endangered subjects of Greenberg's much-praised new Four Fish, which also addresses bass, cod, and tuna. It joins the growing body of literature on overfishing (see Bottomfeeder, The Empty Ocean, The End of the Line, etc.), a subject also inextricably linked to climate change, locally sourced food, fish farming, and population growth. As we know from Mark Kurlansky's Cod book, huge and hugely profitable fisheries can disappear within a generation. Atlantic salmon experienced a similar collapse; and our own Pacific coast salmon--south of Alaska--have never really recovered from dam mania. And at the same time, many question the safety of farm-raised fish. All of which means we may have to change what we eat--and how much we eat--from the oceans. The author notes, "Dining on a 500-pound bluefin tuna is the seafood equivalent of driving a Hummer." BRIAN MILLER
