Time to End the 1500 Mile Ceasar Salad

"Food Miles" refer to the distance that your food has been transported between its source farm and where you buy it. Food miles are one measure of the amount of energy used to transport your food and the consequent pollutants released by that transport. Estimates vary but transport may account for 20% or more of the total energy use associated with the provision of a given food item. As such, Food Miles are a relatively simple statistic that can be used to demonstrate the ecological importance of local foods.
Seventeen percent of this nation’s petroleum consumption is dedicated to on-the-farm food production. Add on processing, packaging, refrigeration and transport of edibles and food takes a big bite out of affordable oil supplies and contributes to pollution.
