A New Form of Farming
In an article posted on The York Time’s website, Michael Pollan writes a letter to our future president. He begins by pointing out that one of the main issues the upcoming president will be dealing with is one that all the candidates seldom mention in their campaign: food. After an in depth discussion of the problem, Pollan provides the three step solution. While I agree with the overall premise of his solution, some specific aspects seem overly dramatic and somewhat unfeasible.
For the last few decades, Americans have had the luxury of extremely inexpensive and profuse food sources. Government policies have supported the mass production of commodity crops, such as corn, soybeans, wheat, and rice, and these crops are the basis of the vast majority of our daily foods. However, According to Pollan, this “era of cheap and abundant food� is about to come to an end.
Pollan also discusses the importance of restructuring the entire food system in order to deal with other important issues, such as the health care crisis, our dependency upon fossil fuels, and the environment (specifically climate change). According to Pollan, the matter in which we presently “grow, process, and eat food in America� is at the heart of such problems.
Our current food system accounts for about 19% of fossil fuel usage. Aside from vehicles, this is more than any other division in the economy. The farm machinery and processing techniques contribute to much of this fossil fuel usage. Furthermore, most fertilizers come from natural gas and most pesticides are derived from petroleum. The usage of such mass amounts of fossil fuels leads to major greenhouse gas emissions, and these emissions are the primary cause of global warming. As Pollan puts it, “When we eat from the industrial-food system, we are eating oil and spewing greenhouse gases.�
The cost of health care is also out of control. Pollan attributes this crisis to many preventable diseases that are associated with a poor diet. With high production and low costs being the number one priority, the quality of food has seen a drastic decrease. This factor, paired with the immense abundance of food, has led to an obesity epidemic in America. Some of America’s top killers, such as heart disease and stroke, are closely linked to cases of obesity.
A “simple solution� to the problem is not foreseeable. Merely increasing agricultural production will not work because the process is so dependent upon a cheap energy source, which we no longer have. In response to the food crisis, Pollan proposed three methods towards a solution. His goals are somewhat “lofty,� but if they were achieved, I believe the state of our country would be much better off.
His first goal is “resolarizing the American farm.� Pollan sees a major problem with monocultures (growing a single crop over a large area of space) corn and soy. Instead, Pollan wants to promote the diversity of crops in a practice known as polyculture. In his letter, Pollan cites many successful forms of polycultures that basically require soil, water, and sunlight. I, too, feel that polycultures have many benefits. Polycultures include tactics such as crop rotation, intercropping, and companion cropping (1). These tactics make the crops much more sustainable against diseases than monocultures, which results in using less pesticides and fertilizers. One study conducted in China involved planting a variety of species of rice in the same field. They saw an 89% increase in yield, and this was chiefly due to a 94% decrease in diseases (1). Pollan pictures a cycle in which “sunlight nourishes the grasses and grains, the plants nourish the animals, the animals then nourish the soil, which in turn nourishes the next season’s grasses and grains.� He feels that all of this can be done without the assistance of fossil fuels.
His next proposition involves “reregionalizing the food system.� America has seen a major increase in demand for local and regional food (such as Farmer’s Markets). Pollan states that we must construct an infrastructure for a regional food economy in order to decentralize it. Localizing food production will allow for fresher and less processed food, which makes if more nutritious. He also proposes several steps that the government should take to further encourage the already occurring local-food movement. I felt some of these were overly drastic, such as banning the use of food stamps on foods considered “junk foods,� but many of the ideas seems promising. Pollan proposed giving grants to towns that provide year-round farmers’ markets. He also proposed lowering the food-safety restrictions placed on small-scale producers, since any problems with local food are not disastrous and can be easily traced. I too feel that locally grown food is much more nutritious. My Grandfather grew up on a family farm and ate the food that came directly from it, and he is currently 92 years old. Furthermore, his older sister is also still alive and healthy.
Pollan’s last goal involves “rebuilding America’s food culture.� Pollan believes we need to do more than merely make healthful and “more sustainable� food available because we cannot guarantee that people will actually eat this food. He proposes using “edible education,� comparable to physical education, to guide today’s children on the importance of eating right. While I agree with this idea, Pollan also argues for planting gardens in all elementary level school, building more proficient kitchens, and having highly trained cafeteria workers. I feel that some of these seem a little “over the top� and unfeasible for lower-income schools. He also feels that the surgeon general should warn the public about the dangers of obesity just as avidly as the dangers of smoking. Furthermore, he feels every food label should specify the calories of fossil fuels that went in to the product’s making. Most importantly, Pollan urges the future president to set an example himself in the White house.
While his solution is thorough, I was left wondering about the advantages and disadvantages of genetically modified crops. Genetically modified crops are plants that have had their DNA changed through combining genes from different organisms (recombinant DNA technology) (2). Scientists can locate genes of importance then transfer favorable characteristics into different organisms. Some of these favorable characteristics may be resistance to an insect, the ability to survive in a harsher climate, or desirable nutrients (3). Some anticipated projects are banana that produce human vaccines to Hepatitis B, rice with increased vitamins and iron, and fruit and nut trees that can produce yields years earlier (4). If Pollan wants to localize the food industry, wouldn’t technology that would allow for plants to live in climates they normally wouldn’t be beneficial? And if he wants to have healthier food, wouldn’t food genetically modified to increase nutrients be advantageous? Could GM crops be otherwise incorporated into his plan? These are all possibilities that merit further discussion.
Pollan is correct in saying that a food crisis is about to occur. Furthermore, he provides ample evidence to link the food problem to other seemingly more important current issues in the US. The solution he discussed would yield positive results, but attaining such an entirely new and complex solution could be difficult. Regardless, as the article stated, “Food is about to demand attention.�
