In a meeting with environmentalists, Elizabeth Edwards talked about the importance of buying locally-produced foods:
“We’ve been moving back to ‘buy local,'” Mrs. Edwards said, outlining a trade policy that “acknowledges the carbon footprint” of transporting fruit.
“I live in North Carolina. I’ll probably never eat a tangerine again,” she said, speaking of a time when the fruit is reaches the price that it “needs” to be.
Being the kind and considerate person that I am, I don’t want the Edwards family to unnecessarily forego the pleasures of tangerine-eating. Therefore, I’ll try to help them out by calculating a vital economic and environmental parameter which shall be known as tangerines per gallon.
This is a very rough and preliminary analysis; tangerine experts and transportation experts are invited to chime in with more data.
