Carlo Petrini, the internationally lauded Italian founder of the Slow Food movement, is on a mission. He envisions a future where no one goes hungry, where land ownership is fair, and where growers’ traditional crops become prized foodstuffs for nations of gastronomes. He lays out the reasons — and the mechanics — to accomplish those things in “Food & Freedom: How the Slow Food Movement is Changing the World” (Rizzoli Ex Libris, $24.95), recently published in John Irving’s English translation of Petrini’s 2013 book, “Cibo e Liberta.”
