The Short and Long of the Food Transport Story
Food is really getting around. One week before Thanksgiving, a new study by the Worldwatch Institute in Washington, D.C., finds that food in the United States now travels 25 percent farther to reach the dinner table than it did just 2 decades ago. In the United Kingdom, food travels 50 percent farther than it did. […]
