The average bite of food on our dinner plates tonight has traveled more than 1500 miles from where it was cultivated. This was not true, however, from September 10-16 for participants of the Chicago-based Localvore Challenge, who only ate foods grown in their region. The event sponsor, the Green City Market, created a list of restaurants that serve meals that are localvore-friendly and a blog site for support from fellow localvores. In addition to reducing their carbon footprint, many participants likely gained awareness of where their food comes from. Such a challenge did limit the food choices that were available to them, as they were not able to snack on mangos and sip on Chilean wine.

The United States imports food from more than 130 countries. The quantity of food has been increasing annually by about 15% since 1991, according to the FDA. Even though Illinois is covered largely by farms, it is estimated that the state imports more than 90% of its food. Corn and soybeans are the most widely grown crops in the state, but the majority of these harvests are not consumed by humans. For example, more than 80% of the corn grown in this country is used for cattle feed, while 1/6 of Illinois corn is utilized for ethanol production. Roughly 80% of the corn and soybeans grown in Illinois are genetically modified. Illinois is built on fertile farmland that is among the richest in the world thanks to glaciers, yet this natural resource is increasingly being developed and covered by concrete. Unfortunately, the rich Illinois soils rarely benefit the inhabitants of Illinois directly, as little of their food is cultivated here.

The demand for local foods in Illinois has grown considerably, and some are saying it is greater than the supply. As the price of fossil fuels increase, this trend may shift. In the meantime, some are voluntarily taking on the challenge of eating local foods. This is a concrete way to influence land use and reduce reliance on fossil fuels, while strengthening the local economy.
