A new book, called “The Locavore’s Dilemma: In Praise of the 10,000 Mile Diet” says it’s a good idea, environmentally, to buy food from countries far away where it is more efficiently produced. Authors Pierre Desrocher, associate geography professor at the University of Toronto, and his wife Hiroko Shimizu, a policy analyst, dismiss the idea of “food miles,” asserting that “it makes more sense to grow a tomato in an unheated greenhouse and truck it than to heat a local greenhouse.”
