In this way, Greenberg underlines the inherent lack of sustainability in our collective fishing processes. Overfishing has had such a devastating impact on the focus populations, and Greenberg advocates for government regulation, showing that fish numbers tend to recover when official intervention gives them breathing room. His dismissal of individual consumer choice as a significant influence on the fishing industry is an interesting departure from other food books that I've read. He does have a point--if governments prevented overfished families from reaching the market in the first place, then ordinary folks wouldn't have to vote with their wallet, as it were. Greenberg thinks subsidizing artisanal fishing is the way to go.
Whether or not that has a snowball's chance in hell of happening, I learned a lot from this book! For instance, I found out that the larval stage has astronomically high mortality rates, so the fish we currently eat are those bred to survive that stage (if farmed), or are tough and/or lucky (if wild). I also had no idea that it takes so much fish feed to grow a fish. I was blissfully ignorant about how Chile, Norway, Alaska, and other places supply our sources of omega-3 fatty acids. I had zero clue that party boats for fishing were a thing. Finally, until I saw the cover of this book, I did not know what the eponymous four fish looked like in their non-filleted form. The more you know!
In conclusion, Four Fish is an informative, enjoyable read that practically radiates with the author's love and enthusiasm for, and deep connection to, the subject matter. The prose is clear, the ideas flow well, and best of all, I came away feeling that there are viable solutions to overfishing...if only we could get our act together, which we occasionally do!
TL;DR: A fun, educational book!
