Chad Heeter, in his book "My Saudi Arabian Breakfast," breaks it down this way, "Food's fossil fuel consumption is 20 percent consumed on the farm; 40 percent burned up in processing, packaging and shipping; another 40 percent is used to store and prepare the food."
What can you do? First, start somewhere; look for local produce food outlets like farmers markets, roadside stands or supermarkets that sell local products. Second, do it now. While the season is winding down, there are still plenty of opportunities for buying local produce.
I am an "everything in moderation" kind of guy, so ease into buying local. Every week, replace a food with a local product. Once you have eased in, try preserving. Drying and freezing are easy methods. Most fruits and some vegetables can be preserved in this manner.
Start planning now for next year. Expand your garden or start a small one if you don't have one. Sit in the warm glow of your home this winter and enjoy the abundance of seed catalogs you can shop in. Remember, moderation. Don't plant a garden that is so big it becomes a burden. If it is your first time, try a potted tomato or a small container garden.
You can also join a CSA (Community Supported Agriculture), a CSA is a member-supported farm in which you buy shares and your shares are returned to you in the form of produce. You can also connect with, or start a community garden. This can be on public land or maybe you can share your backyard.
Also, think like a squirrel. Seek out foods that keep well, such as nuts, honey, winter squash, some apple varieties, potatoes and sweet potatoes and stock up. If you don't have a cool place to store them, make you own "root cellar" by digging a hole and using straw as an insulator.
Lastly, you can double your recipes. Some call it mega cooking. Really it is just cooking more than needed for one meal, and freezing it for a second meal. Unlike leftovers, this is a purposeful act. More than one dish and sometimes only partially cooked.
So, enjoy the fall harvest. Pick up some apples or other produce and if you are feeling really brave, buy a pumpkin and make a pie, not a jack-o'-lantern.
