In the book, Greenberg addresses the four most dominant fish on the market — salmon, tuna, bass and cod — and talks about the problems with current farming and the need for healthier, more sustainable practices.
A wide net is cast as the author examines how popular fish are being over-farmed, undernourished and exploited. He also offers some solutions, suggesting ideas like cutting back on industrial fishing, establishing no-catch areas in oceans and protecting low food-chain fish from being fed to livestock.
“I’m neither anti-fishing, nor anti-fish farms. It’s more about the intelligence raising and consciousness raising that needs to go on with policymakers, consumers and the industry,” Greenberg told a Toronto Star reporter while discussing the book. “No single thing is going to do this. We have to recognize that this is the major food issue of the decade, if not the century. We can get it right, but we can’t stop at choosing the right fish. We have to fight the right fight.”
