Buying locally grown food has become increasingly popular. Food often travels a great distance from its place of production before being consumed. A carrot on someone's plate in Iowa may have traveled 1,600 miles from California. The potato beside it could have come 1,200 miles from Idaho. Shipping food long distances uses large amounts of fossil fuels, which has an adverse effect on the environment. This is one reason many people are starting to buy local foods.
