Americans put almost as much fossil fuel into our
refrigerators as our cars. We're consuming about 400 gallons of oil a year per
citizen-about 17% of our nation's energy use-for agriculture, a close second to
our vehicular use. Tractors, combines, harvesters, irrigation, sprayers,
tillers, balers, and other equipment all use petroleum. Even bigger gas guzzlers
on the farm are not the machines, but so-called inputs. Synthetic fertilizers,
pesticides, and herbicides use oil and natural gas as their starting materials
and in their manufacturing. More than a quarter of all farming energy goes into
synthetic fertilizers.
But, getting the crop from seed to harvest takes only one-fifth
of the total oil used for our food. The lion's share is consumed during the
trip from the farm to your plate. Each food item in a typical US meal has
traveled an average of 1,500 miles. In addition to direct transport, other
fuel-thirsty steps include processing (drying, milling, cutting, sorting and
baking), packaging, warehousing, and refrigeration. Energy calories consumed by
production, packaging, and shipping far outweigh the energy calories we receive
from the food.
A quick way to improve food-related fuel economy would be to buy
a quart of motor oil and drink it. More palatable options are available. If
every US citizen ate just one meal a week (any meal) composed of locally and
organically raised meats and produce, we would reduce our country's oil
consumption by over 1.1 million barrels of oil every week. That's not gallons,
but barrels. Small changes in buying habits can make big differences. Becoming
a less energy-dependent nation may just need to start with a good breakfast.
