Just found this, and I recently sussed that it's by a friend of mine. Man, still waters run deep on some people; if I'd published anything, I'd be crowing about it all over the place. Anyway, here's a link to his facebook group
about the topics covered in the book. Fascinating stuff about how high level economic factors like NAFTA affect the transport of livestock, how our (and I'm using our in the global sense) farming practices incubate disease. Sadly, the book appears to be written in academicese, so I might just stick to the fb updates.
