The authors are Pierre Desrochers and Hiroko Shimizu, and the subtitle is In Praise of the 10,000 Mile Diet:
The publisher’s page summarizes it thus:
Today’s food activists think that “sustainable farming” and “eating local” are the way to solve a host of perceived problems with our modern food supply system. But after a thorough review of the evidence, Pierre Desrochers and Hiroko Shimizu have concluded that these claims are mistaken.
In The Locavore’s Dilemma they explain the history, science, and economics of food supply to reveal what locavores miss or misunderstand: the real environmental impacts of agricultural production; the drudgery of subsistence farming; and the essential role large-scale, industrial producers play in making food more available, varied, affordable, and nutritionally rich than ever before in history.
They show how eliminating agriculture subsidies and opening up international trade, not reducing food miles, is the real route to sustainability; and why eating globally, not only locally, is the way to save the planet.
