The average meal travels 1,200 miles by truck, ship, and/or plane to reach your dining room table. If, once a month, 100,000 people bought their weekly produce at a local farmers' market instead of at a grocery store, they would collectively prevent more than 3,000 tons of carbon dioxide from being emitted thanks to reduced transportation of the food.
What You Should Know
- Local farmers can offer produce varieties bred for taste and freshness rather than for shipping and long shelf life. In contrast, fruits and vegetables shipped from distant states and countries can spend as many as 7-14 days in transit before they arrive in the supermarket.
- Local food requires fewer packing materials and produces significantly less carbon dioxide emissions than food that has been shipped.
- Buying
local food keeps your dollars circulating in your community and also
helps to make farming more profitable and selling farmland for
development less attractive.
Easy Things You Can Do
Eat locally grown food. When you buy locally grown produce or locally butchered meat, the benefits are endless. First, you help prevent global warming because your food doesn't travel across the country (or the continent!) in order to reach your kitchen table. Second, you support your local economy. Third, locally grown produce is fresher, better tasting, and more nutritious than transported produce (Since nutritional value starts to decline as soon as food is picked or harvested). Locally grown produce is often cheaper and has less packaging. Last, by buying locally grown food, you promote your region's self-reliance and avoid supporting huge farming corporations that put their own profits over the environment.- Shop at your local farmers' market, join a local CSA (Community Supported Agriculture cooperative) and ask your grocery store manager to set up a special section for locally grown foods.

Eat in season. There's a reason why strawberries taste so good in June and cost a fortune in January. Although financially you may be able to buy fruits out of season, it's better that you don't for the environment's sake. If you eat cantaloupe in January, it was most likely shipped by air, train, and truck from South America, or Florida. When you eat it in July, however, it was probably driven in from a neighboring county. Here's a basic guide of what to eat during each season (this will vary by climate):
