Paying attention to where the goods you buy come from is a good way to help lessen your impact on the environment. When you shop locally, you support your local economy, too. For example, when you buy produce at farmers' markets that allow only local farmers to sell their produce, you're cutting down on the number of miles the food travels to get to market. The fewer the miles, the lower the carbon dioxide emissions associated with transporting that food. There may be fewer energy and packaging costs, too. The same goes for buying from local artisans and retailers that specialize in locally produced goods.
