Fascinating. I feel like every year or so a new book is written along the topic of something like this though: Fish, Salt, Grain, Money, Paper, etc and how that thing was responsible for modern civilization. I commend the author for bringing this idea to the forefront but its likely disingenuous to think that Fish and Fishing has as the author says, "created the modern world" more so than any of these other things.

Still makes for a fascinating read... Plus eventually we'd be able to run ml on the articles to reach a concensus maybe xD
