Cod caught off Norway is shipped to China to be turned into filets, then shipped back to Norway for sale. Argentine lemons fill supermarket shelves on the Citrus Coast of Spain, as local lemons rot on the ground. Half of Europe’s peas are grown and packaged in Kenya.
In the United States, FreshDirect proclaims kiwi season has expanded to “All year!” now that Italy has become the world’s leading supplier of New Zealand’s national fruit, taking over in the Southern Hemisphere’s winter.
Food has moved around the world since Europeans brought tea from China, but never at the speed or in the amounts it has over the last few years. Consumers in not only the richest nations but, increasingly, the developing world expect food whenever they crave it, with no concession to season or geography.
Increasingly efficient global transport networks make it practical to bring food before it spoils from distant places where labor costs are lower. And the penetration of mega-markets in nations from China to Mexico with supply and distribution chains that gird the globe — like Wal-Mart, Carrefour and Tesco — has accelerated the trend.
But the movable feast comes at a cost: pollution — especially carbon dioxide, the main global warming gas — from transporting the food.
