I found the following article in the Organic Consumers Association Newsletter dated 11/30/05. It makes some excellent arguments for eating locally grown foods. Some of the statistics are rather startling. Read on!

Gas Guzzling Food

The SUV in the Pantry
by Thomas Starrs
I spend a fair amount of time thinking about how to reduce my family's
dependence on energy, particularly energy derived from fossil fuels. I
commute to work by bicycle or bus, install compact fluorescents when light
bulbs burn out, replace major appliances with the most efficient ones I can
afford, and cast jealous glances at my friends who drive hybrids or
alternative-fueled vehicles. But until recently, I didn't think of myself as
an energy glutton because of the food I eat.
Then I read an astonishing statistic: It takes about 10 fossil fuel calories
to produce each food calorie in the average American diet. So if your daily
food intake is 2,000 calories, then it took 20,000 calories to grow that
food and get it to you. In more familiar units, this means that growing,
processing and delivering the food consumed by a family of four each year
requires the equivalent of almost 34,000 kilowatt-hours (kWh) of energy, or
more than 930 gallons of gasoline (for comparison, the average U.S.
household annually consumes about 10,800 kWh of electricity, or about 1,070
gallons of gasoline). [Webnote: This last sentence should read... "for comparison, the average U.S. household annually consumes about 10,800 kWh of electricity, AND about 1,070 gallons of gasoline"] **Please see OCA webnote at foot of this article**
In other words, we use about as much energy to grow our food as to power our
homes or fuel our cars.
