Why Food Security Matters to You

I believe there are two aspects to food security, both of which should concern all of us. The first and probably less familiar aspect is that of security from contamination. Contamination can take many forms, from E. coli and other biological agents to pesticides to heavy metals to animal hormones to discarded pharmaceuticals. The reason I add this as a factor of food security is because contaminated food is as good as no food at all. The second aspect is simple access to fresh, healthy food. Some inner cities of our large metropolises like Chicago and Detroit contain food deserts where no grocery stores exist for many miles. The only options people in these areas have for sustenance are fast food restaurants and convenience stores that sell highly processed and packaged food products.

For those of use fortunate enough to not live in a food desert we also need to be concerned about the availability of healthy, fresh food. A quick look at how our food is produced and distributed will outline some areas for concern. In the US the average super market travel distance for fresh fruit and vegetables is between 1500 to 2500 miles. Think about this for a moment. That lettuce you are eating in your salad tonight probably traveled farther to get to your refrigerator than you did on your last vacation. So what does this have to do with food security? Since our food network is stretched so long and is so reliant on cheap fuel, the interstate highway system and an enormous fleet of trucks, it is susceptible to many kinds of disruptions.

This is most apparent during natural disasters such as hurricanes. Under normal circumstances the stock in most grocery stores becomes depleted in three days. This means three days without any truck deliveries and your local store has no more food for you to purchase. Fortunately, natural disasters are not normal circumstances. We have all seen footage of empty store shelves hours before a large hurricane is scheduled to make landfall in an area. Luckily, most truck service is restored only hours after a hurricane has passed and the stores can be restocked. Sometimes, however, that is not the case.

As most of us can remember, after hurricane Katrina, the city of New Orleans descended into anarchy and chaos within a few days without drinkable water, electricity or food supplies from the outside world. Shocked that a city in the US could fail so quickly (and appalled at the apparent lack of federal response), I drove from Chicago down to Baton Rouge, the largest nearby city where a relief effort was being staged, to help. Inside the gymnasium and sports arena at LSU the Red Cross (with no help from FEMA or any other federal agency) was staffing a small city of cots, medical services and a cafeteria to house and feed five to six thousand refugees from the flooded city 50 miles to the south. The biggest impression I took away from my experience is how fragile is our modern lifestyle.

So what does this have to do with food security? Unfortunately, hurricanes are not the only threats to our thin and delicate web of food production and distribution. Drought, spikes in fuel prices, labor disputes and strikes, failing infrastructure, economic panic (e.g. fall of 2008), resource shortages, terrorism and severe weather events can all disrupt our steady supply of fresh, healthy food. But even if none of these calamities occur, we still have to contend with the other aspect of food security, contamination.

I've been considering all of these issues for several years and the simple conclusion I can't escape is the best way to improve one's food security is to grow more of it yourself. And growing your own food has the added benefit of reducing green house gases due to current energy intensive, factory farming practices and long travel distance by truck. And can you get more fresh than eating something five minutes after it is picked from the ground?

Every home owner has some kind of yard with some amount of ornamental vegetation, depending in which area of the country you live. Most of us own a swath of grass, the stereotypical American lawn, upon which we spend an inordinate amount of our summer months to maintain. Wouldn't it be a better use of our time and resources if we replaced some of that grass to grow something we can actually eat? Now that's food for thought.
