Mark Kurlansky, who has previously authored compendia on topics including Cod and Salt, here switches focus to chronicle the demise of the storied salmon throughout its wide Pacific and Atlantic ranges.
Apart from a few whimsical meanders into a history of fly-tying and samples of salmon recipes from various cultures, it is a brutal and stark account of the relentless pressures generated by a grand “Manifest Destiny” mentality which accepts the extinction of an ancient icon as a small, hardly accountable cost to achieve the ambitions of hydro power, forestry exploitation, urbanisation, mining, irrigation et al.
