Dig for Victory




The victory gardens of World War II in America contributed food with a value of $1.2 billion by 1945, in the backyards of 20 million households. Victory gardens were once the answer to the question of food supply and provenance, delivered with a morale-boosting reward for labor. Publicly promoted by Eleanor Roosevelt at the White House in 1943 (she tried to plant a vegetable garden in 1941 but was discouraged by the USDA for being unpatriotic), the effort was repeated by Michelle Obama in 2009. The resurgence of the edible garden in American public life is due to the rise of locavores including Michael Pollan, who writes, “The power of cleverly designed polycultures to produce large amounts of food from little more than soil, water and sunlight has been proved... (they) can produce more food per acre than conventional monocultures, and food of a much higher nutritional value.”[i]

In America today, fresh food supplies are ubiquitous with rapidly expanding retail options. Food is found at the corner store, the big box, and the dollar store. The rarest spices, the most indulgent fruits, and the leanest cuts may be had with very little preparation or effort. Only the miles that food has traveled has increased – it is unlikely that your shrimp come from Mississippi or your rice from Louisiana when refrigerated containers bring them so much more cheaply from China or Central America. The unintended spatial consequences of access to the unseasonable are pollution, waste, higher traffic, wider roads, isolated distribution centers… and the consequent loss in flavor that accompanies the time in transit.

The average consumption of fruits and vegetables is 708 lbs per person in the U.S.; even if backyard food plots only contribute one quarter of our daily needs, they save billions of miles of transport and billions of tons of carbon dioxide emissions. Community-scaled urban farming is achievable within most cities, even at a small scale. Interest grows in times of economic hardship – waiting lists for garden allotments in central London in the past few years have become so choked that many lists have been discarded.

Home-grown produce requires no increase of industrial agricultural lands and labor, does not unbalance the world economy, does not require transportation, and does not use significant amounts of pesticides or fertilizers.  As a defensive strategy in the modern world, food security ranks with energy security, especially in response to recent food riots and increasing prices. Food security depends on decentralized food production: small farmers and rooftop gardens, backyards and planter boxes.  And the results taste a lot better.

Heavy Breathing


A recent poll here shows that people think that the air quality in their neighborhood is better than the air quality in the region… and they may be right.  Six of the top ten polluters in the state are located in south Mississippi, including three power plants plus a chemical plant, oil refinery, and paper mill. 

The EPA determines standards for six criteria pollutants.  These include particulate matter, sulfur dioxide (SO2), nitrogen dioxide (NO2), lead (Pb), and carbon monoxide (CO), as well as ozone.  Ozone in the upper atmosphere forms a protective layer against UV rays, so holes in the ozone layer 6-30 miles above the earth are a problem; down here in the lower atmosphere, ozone is created when a chemical reaction occurs between emissions such as nitrogen oxides and volatile organic compounds meet sunlight and cause a breathing hazard.

The allowable amount of ozone in the air is 75 parts per billion.  The EPA issued a draft standard earlier this year intended to lower the acceptable level of ozone to 60-70 ppb.  From the EPA website:  “Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ground-level ozone also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue.

The proposed EPA standard set off a firestorm of controversy about the effect on industry and jobs.  This is a default maneuver by lobbyists, and happens whenever restrictions might cut into profits.  Industry has made these arguments before. They almost always turn out to be exaggerated.” (New York Times editorial, “A Bad Call on Ozone”, September 3, 2011.)  Yesterday, the Obama Administration responded to the pressure and abandoned adoption of the stricter ozone standard, citing the mandatory review scheduled for 2013.

The old EPA standard isn’t going to help my neighborhood’s air quality improve, and we are already close to non-attainment status.  Non-attainment has a direct effect on state funding through the “transportation conformity” requirement.  No new highway projects.  No dollars for road improvements.  Altered traffic patterns, reducing single-occupancy vehicles, and improving transit systems and bicycle access are required.

In southern California, meteorologists announce air quality daily, newspapers report at a neighborhood level, and bank readerboards list hazardous days along with the time and temperature.  Why do people think that where they live has safer air than where they work?  The reassurance of a tree canopy leads us to believe in the efficacy of their filtering process.  The lack of visible smog, smoke, and particles in the air follows the adage “out of sight, out of mind.”  The smokestacks may be the visible symbol of pollution, but the emissions are real, whether we see them or not.
