So what's wrong with cheap food and cheap meat — especially in a world in which more than 1 billion people go hungry? A lot. For one thing, not all food is equally inexpensive; fruits and vegetables don't receive the same price supports as grains. A study in the American Journal of Clinical Nutrition found that a dollar could buy 1,200 calories of potato chips or 875 calories of soda but just 250 calories of vegetables or 170 calories of fresh fruit. With the backing of the government, farmers are producing more calories — some 500 more per person per day since the 1970s — but too many are unhealthy calories. Given that, it's no surprise we're so fat; it simply costs too much to be thin.
Our expanding girth is just one consequence of mainstream farming. Another is chemicals. No one doubts the power of chemical fertilizer to pull more crop from a field. American farmers now produce an astounding 153 bu. of corn per acre, up from 118 as recently as 1990. But the quantity of that fertilizer is flat-out scary: more than 10 million tons for corn alone — and nearly 23 million for all crops. When runoff from the fields of the Midwest reaches the Gulf of Mexico, it contributes to what's known as a dead zone, a seasonal, approximately 6,000-sq.-mi. area that has almost no oxygen and therefore almost no sea life. Because of the dead zone, the $2.8 billion Gulf of Mexico fishing industry loses 212,000 metric tons of seafood a year, and around the world, there are nearly 400 similar dead zones. Even as we produce more high-fat, high-calorie foods, we destroy one of our leanest and healthiest sources of protein. (See nine kid foods to avoid.)
The food industry's degradation of animal life, of course, isn't limited to fish. Though we might still like to imagine our food being raised by Old MacDonald, chances are your burger or your sausage came from what are called concentrated-animal feeding operations (CAFOs), which are every bit as industrial as they sound. In CAFOs, large numbers of animals — 1,000 or more in the case of cattle and tens of thousands for chicken and pigs — are kept in close, concentrated conditions and fattened up for slaughter as fast as possible, contributing to efficiencies of scale and thus lower prices. But animals aren't widgets with legs. They're living creatures, and there are consequences to packing them in prison-like conditions. For instance: Where does all that manure go?
Pound for pound, a pig produces approximately four times the amount of waste a human does, and what factory farms do with that mess gets comparatively little oversight. Most hog waste is disposed of in open-air lagoons, which can overflow in heavy rain and contaminate nearby streams and rivers. "This creek that we used to wade in, that creek that our parents could drink out of, our kids can't even play in anymore," says Jayne Clampitt, a farmer in Independence, Iowa, who lives near a number of hog farms.
To stay alive and grow in such conditions, farm animals need pharmaceutical help, which can have further damaging consequences for humans. Overuse of antibiotics on farm animals leads, inevitably, to antibiotic-resistant bacteria, and the same bugs that infect animals can infect us too. The UCS estimates that about 70% of antimicrobial drugs used in America are given not to people but to animals, which means we're breeding more of those deadly organisms every day. The Institute of Medicine estimated in 1998 that antibiotic resistance cost the public-health system $4 billion to $5 billion a year — a figure that's almost certainly higher now. "I don't think CAFOs would be able to function as they do now without the widespread use of antibiotics," says Robert Martin, who was the executive director of the Pew Commission on Industrial Farm Animal Production.
Cheap food is very expensive! Think of PEI. The health budget is now 500 million a years for a total population of 140,000. The biggest driver for this? Diabetes, heart disease and cancer - all chronic diseases related to lifestyle and diet. When I came here in 1995 the budget was 300 million. What will it be in 2015? At this rate a $billion! A major factor - cheap food.
What about PEI's rivers, water sheds etc - nitrates in our water, rivers silting up - what will our water system be like in 20 years at this rate?
What about our food system. Now we grow less than 10% of what we eat here. We have given up control of our food to people from far away. When peak oil comes what then?
Time to think more about the cost of cheap food.
