Buy Your Food Locally
Food Miles, Resources and the Environment
"Food miles" refer to the distance a food item travels from the farm to your home. The food miles for items you buy in the grocery store tend to be 27 times higher than the food miles for goods bought from local sources.i
In the U.S., the average grocery store’s produce travels nearly 1,500 miles between the farm where it was grown and your refrigerator.ii About 40% of our fruit is produced overseas and, even though broccoli is likely grown within 20 miles of the average American’s house, the broccoli we buy at the supermarket travels an average 1,800 miles to get there. Notably, 9% of our red meat comes from foreign countries, including locations as far away as Australia and New Zealand.iii
So how does our food travel from farm field to grocery store? It’s trucked across the country, hauled in freighter ships over oceans, and flown around the world.
A tremendous amount of fossil fuel is used to transport foods such long distances. Combustion of these fuels releases carbon dioxide, sulfur dioxide, particulate matter and other pollutants into the atmosphere, contributing to global climate change, acid rain, smog and air pollution. Even the refrigeration required to keep your fruits, vegetables, dairy products and meats from spoiling burns up energy.
Food processors also use a large amount of paper and plastic packaging to keep food fresh (or at least looking fresh) for a longer period of time. This packaging eventually becomes waste that is difficult, if not impossible, to reuse or recycle.
Aside from the environmental harm that can result from processing, packaging and transporting long-distance foods, the industrial farms on which these foods are often produced are major sources of air and water pollution. Small, local farms tend to be run by farmers who live on their land and work hard to preserve it. Buying local means you can talk directly to the farmer growing your food and find out what they do and how they do it. Do they grow their food organically? If they're not certified organic, ask them why. Many small farms, even if they haven't taken the certification step, still utilize sustainable or organic farming methods that help protect the air, soil and water.
Health and Nutrition
Buying food from local farms means getting food when it’s at its prime. Fresh food from local farms is healthier than industrially-farmed products because the food doesn’t spend days in trucks and on store shelves losing nutrients.v
Food transported short distances is fresher (and, therefore, safer) than food that travels long distances. Local food has less of an opportunity to wilt and rot whereas large-scale food manufacturers must go to extreme lengths to extend shelf-life since there is such a delay between harvest and consumption. Preservatives are commonly used to keep foods stable longer, and are potentially hazardous to human health. Industrially-produced foods are also difficult to grow without pesticides, chemical fertilizers, antibiotics and growth hormones, all of which can be damaging to both the environment and human health.
Local foods from small farms usually undergo minimal processing, are produced in relatively small quantities, and are distributed within a few dozen miles of where they originate. Food produced on industrial farms, however, is distributed throughout the country and world, creating the potential for disease-carrying food from a single factory farm to spread rapidly throughout the entire country. The 2006 E coli outbreak is a good example of this, as contaminated spinach from a single region in California managed to sicken people in 26 states.vi
Products such as ground beef, which is pooled from hundreds of different animals, are of particular concern. The meat from a single diseased cow could end up contaminating hundreds of pounds of food distributed to thousands of people. Once such a product is on shelves, it is very difficult to determine where the contaminated meat came from. Preventing or controlling disease outbreaks in such a system is nearly impossible.
In addition, the U.S. Department of Agriculture, the federal agency which inspects meat and poultry, does not have the authority to order a recall of dangerous or mislabled product once it has left a plant. The agency can only urge the company to issue a recall themselves. This often leads to delays in notifying the public, wasting valuable time and increasing the odds that unsafe products get eaten by consumers.
Family Farms and Community
According to the USDA, the U.S. has lost over five million farms since 1935.vii Family farms are going out of business at break-neck speed, causing rural communities to deteriorate. The U.S. loses two acres of farmland each minute as cities and suburbs spread into the surrounding communities.viii By supporting local farms near suburban areas and around cities, you help keep farmers on the land, and, at the same time, preserve open spaces and counteract urban sprawl.
