What is the author's style in Cod: A Biography of the Fish That Changed the World by Mark Kurlansky?

The book is delivered from the abstracted third-person, omniscient, point of view common to modern journalism. The text is obviously intended for a broad audience and the construction offers no particular hindrance to any reader of the high-school level or above. Little material is controversial and topics that might be controversial are typically treated in a so-called politically-correct way. For example, slavery is mentioned as it influenced the early American cod fisheries—but it is also soundly condemned.
