Migrant Farm Workers in Florida and Their Struggle for Environmental Justice

October 29, 2012

Introduction

The average American gives little thought to tomatoes. The weekly trip to the grocery store never disappoints; the red orbs are always there, no matter the season. January? No problem. The tomatoes displayed on the shelves in deep winter actually look no different than the ones that graced the same shelves in July. Likewise, when buying a Whopper from Burger King, one simply expects there to be a slice or two of fresh tomato on the patty. Never mind that snow had to be brushed off the car earlier that day; tomatoes are always available. Magically.

Where do those winter tomatoes come from, and what has happened to our system of agriculture that makes it seem so easy to have tomatoes on our dinner plate year round? Most people recognize that the miracle of the tomatoes happens far away in the South, where the sun shines high in the sky throughout the winter months. Beyond that though, there is a void of understanding. There is a hidden and tragic aspect to the seemingly bountiful flow of our most ubiquitous fruit that most people are unaware of. Our system of retailing the abundance of agriculture has detached the consumer from the farm so much that the true cost of our food is not only deeply hidden from the consumer, but that cost is in fact difficult to discover even when a conscientious consumer wants to make the effort to find out.

Some of the worst abuses of farm workers prevail today because the workers are invisible to society.

In this paper I will introduce a group of people who labor in the fields to produce our food, and specifically winter tomatoes. The paper will describe the struggle of migrant farm workers in southwestern Florida to work safely and fairly. I will use indicators described by David Pellow in his book, “Garbage Wars” (1), to show that the working conditions for that group of laborers warrants the label of environmental injustice. The paper will explore some of the injustices that have exploited this class of workers to the benefit of industrial farms and indirectly, to our own benefit as consumers. It will discuss some of the historical background of the injustices in order to help us better understand the roots of the problem. It will identify the multiple stakeholder relationships, and will delve into the specific struggles and actions these workers and others have taken to resist the injustices. Finally, the paper will consider the issues that continue to face the workers in the road towards environmental justice.

A History of Agriculture in Immokalee

The hub of tomato agriculture in Florida is centered in a community in the far southwest portion of the state, called Immokalee. About twenty miles north, the Caloosahatchee River connects the Gulf of Mexico with Lake Okeechobee. Immokalee itself is on high ground, an important feature that attracted agribusiness to the area, because the land doesn’t require draining. Prior to the use of land by agriculture, though, Immokalee was a small cattle town. In 1921, the Atlantic Coast Line Railway was extended south, connecting Immokalee to the rest of the country, facilitating commerce. Construction of the railroad attracted US-born Blacks to the area to fill the need for labor.

In the 1930’s, lumber developed as a new use of the land around Immokalee. Timber attracted more workers, and the sawmill owners built living quarters for the workers. Resin from the tree stumps was sold for use in explosives and medicine, and the stumps were removed for that purpose. Before long, however, the virgin cypress and pine were logged out, and the sawmills had to close down. With the trees and even the stumps cleared out, the land was ready for vegetable farming.

In 1940, Immokalee Growers, Inc. was established as the first packinghouse in Immokalee, and with that, agribusiness began shooting down roots in the region.

With the advent of the Second World War, so many farmworkers left the fields of Florida (and across the country) either to fight in the war or to work in various war industries, that their vacancies left a serious shortage of workers to harvest the crops needed to feed the nation. To answer that need, US president Franklin D. Roosevelt negotiated an agreement with Mexico in 1942 that offered a guarantee of basic protections to Mexican workers. Known as the “Bracero Program”, the Mexican Farm Labor Program sponsored millions of guest workers from Mexico from 1942 to 1964. (2) (3) Many of those workers came to Immokalee.

As land was devoted to agriculture, the need for workers grew, and Mexicans immigrated in droves under the Bracero Program to fill that need. They left poverty and corruption in their home country in the hopes of finding work in Immokalee. Most had very little education and spoke no English, but they had what was needed for the fields: experience and drive. They just wanted to work and make better lives for themselves.

In 1959, American-owned businesses in Cuba were taken over by Castro. During the ensuing revolution, many people left Cuba and came to the Immokalee area because of the availability of work. In 1962, a US trade embargo was established against the purchase of products from Cuba, and this is when big vegetable growers started arriving in Immokalee and agribusiness started to take off in Southern Florida. Improvements in technology (e.g. culture beds, drip irrigation, fertilization, plastic mulching) made it possible to grow tomatoes there, despite the infertile, sandy soil. During that time the workforce was still dominated by Blacks and destitute Whites, but the population of Latinos (mostly Cubans, and Mexicans) was growing. Other workers started coming from Puerto Rico, and Tejanos (Mexicans from Texas) came from southeast Texas to work in Immokalee during the 60’s.

In 1980, Fidel Castro’s regime announced that Cubans were free to emigrate to the US from a single port, Mariel. The US welcomed the Cubans from this “Freedom Flotilla”, as refugees. Although not as welcomed by the Americans as the Cubans, Haitians came along with them by the thousands, many staying in Miami, and others moving on to rural communities, like Immokalee.

Guatemalans first came to the Immokalee area in the early 1980’s. In the mid-1980s they were able to file asylum claims because of the war in their home country.

In the 80’s new immigrants arrived in Immokalee every day with no money and no place to stay. They needed to live in proximity to the parking lots where buses picked up workers for the fields, so the south side of Immokalee became more and more crowded. The place named “Immokalee” from the Seminole word for “My Home”, had no room for the hopeful workers. They slept under trailers, under trees, in cardboard boxes. Once they worked and were able to save a little money, they could rent a place to stay. Slumlords, however, charged exorbitant prices for them to share a trailer or room or shack with other immigrants.

In the 1990’s the North American Free Trade Agreement (NAFTA), and the devaluation of the Mexican peso, made it easier for farmers in Mexico to compete with American growers, and subsequently, the influx of immigrants settled down to a more steady pace. Florida’s tomato revenues went down 20% during that time; some tomato companies in Immokalee went out of business. Still, Immokalee remained one of the first places new immigrants came.

The immigrants arrived in Immokalee with only a few dollars and their clothes in a bag, and they spoke no English. They came to Immokalee because they heard there was work there. Once here, they work in the fields of all winter, sending what they can back to their loved ones in their home country. At the end of the season, they pack everything they own into bags and migrate north for the summer season to follow the crops. (3)

The Men and Women Who Pick the Food We Eat

Facing extreme poverty in their home countries, men and women come at great risk to Immokalee with a deep hope for a better life. Today Mexicans make up over 50% of Immokalee’s population. 8-10% are Haitians, and 5-10% Guatemalans. (3) Many leave behind family members, including children or ailing parents unable to make the risky journey. Many speak only their native dialects, having no English skills and in fact, very little Spanish. They come with little education, but they nurture great courage in the face of the unfamiliar culture, harboring the hope that they may be able to earn money to send home to their families. They come prepared to work hard, and are driven by desperate need.

Since the Bracero Program, legal immigration has become very difficult for Mexicans. Immigration from any country requires a sponsor (a company or close relative who is a permanent resident or US citizen) to petition to bring them in. Even with a sponsor, the limit on visas issued per year per country means that a potential immigrant might have to wait years before a visa becomes available. Because of this, many prospective migrants turn to “coyotes,” smugglers who facilitate the migration to America, for a price. Many of these migrants show up at the fields of Immokalee, where they work for cash. (3) According to the National Agricultural Workers Survey (NAWS), half of all hired crop farmworkers lack legal authorization to work in the United States. (5)

Picking tomatoes is “piecework”, which means workers are paid by the bushel picked, not by the hour. Fresh market tomatoes must be picked by hand, because splits, dents, and gouges from automated machines are unacceptable in a fresh tomato. In this way, the fresh-market tomato agricultural methods in Immokalee differ from those whose tomatoes are destined for canning purposes; canning tomatoes are harvested by machine.

Because they are paid by the bushel, workers must be fast and able to endure long (usually 12-hour) days of back-breaking work. They must also be able to run their bushel baskets quickly to the waiting truck; those workers assigned areas farther from the truck are paid less, because they are forced to spend more time running than picking. On average, workers pick 20 buckets per hour. (6) Without even considering running time, that means the workers fill a bucket in about three minutes time.

I wanted to have first-hand experience of farming myself, so this past summer I volunteered to work part-time on an organic produce farm in central Illinois. Since the tomatoes were destined for local markets, we harvested only the fruits that had ripened on the vine, so extra care was needed in handling the tomatoes because of their ripened tenderness. Instead of bushel baskets, in which the weight of tomatoes would certainly crush those on the bottom, we used very shallow baskets. In contrast to the three-minute average picking time achieved by the workers described above, I was only able to pick one shallow bucket in about a half-hour’s time. The experienced farm hands were able to pick much faster than I, but were still significantly slower than three minutes per bucket. This experience gave me a real appreciation for the kind of work demanded of migrant workers. In order to fill a bushel basket with tomatoes, albeit solid fruit, those workers’ hand and arm movements must be lightning fast.

The pay for workers is no different than it was 30 years ago, and when adjusted for inflation, it’s about half of what it was then (7). Because they don’t have their own vehicles, workers are bussed to the farms. They are not compensated for time spent waiting for morning dew to dry, or for inclement weather. Less than a tenth of migrant farmworkers have health insurance, and they seldom receive overtime pay. The 2008 Profile of Hired Farmworkers (5) reports that, at $350, the median weekly earnings of full-time farm workers are only 59% those of all wage/salary employees, and that migrant farmworkers earn even less than settled farmworkers. Because of the seasonal nature of their work, harvest weeks are limited, and farm workers in Florida report annual incomes of between $7000 and $9000. (6)

Their health is poorer, and their children face more difficult educational challenges than their settled peers. The housing conditions are substandard because of “crowding, poor sanitation, poor housing quality, proximity to pesticides, and lax inspection and enforcement of housing regulations.” Agricultural work is “among the most hazardous occupations in the United States, and farmworker health remains a considerable occupational concern. Farmworkers face exposure to pesticides, risk of heat exhaustion and heat stroke, inadequate sanitary facilities, and obstacles in obtaining health care due to high costs and language barriers.” (5)

When we as American consumers purchase cheap tomatoes that come from the farms of Immokalee, we are benefitting from a system that is unfair to the workers. The men and women who work the fields are essentially subsidizing the price of our cheap tomatoes through their lack of fair wages for the dangerous service they provide.

Chemical Exposure

Because of the poor soil quality in Florida, research to improve growing conditions for tomato production began in the mid 1940’s. Growers avoided increases in various plant pathogens and weeds associated with repeated cropping, by moving their growing enterprises to previously un-cropped land every couple of years. However during the late 1950’s, the availability of inexpensive land was reduced due to the growth of urban populations competing for the land, and growers faced the dilemma of having to reuse the same land for their crops in order to be profitable. In order to control a complex known as “old land disease” in fresh market tomato crops, a system was developed in the 1960’s that included in-the-row fumigation, followed by the application of a polyethylene mulch and fertilizers, with maintenance of a high water table. This system was widely employed to enable the frequent re-use of the land for tomato crops. Modified and improved since the 1970’s, it is still the system of choice for the majority of Florida tomato growers. (8)

Over 30 chemicals are routinely sprayed onto a tomato field during the growing season (9). Many are rated highly toxic and some (metribuzin, mancozeb, and avermectin) are known to be “developmental and reproductive toxins”, according to the Pesticide Action Network (10).

Pesticide exposure results in toxic effects that can be both acute and chronic. Depending on the classification of the pesticide, symptoms may vary, but acute symptoms include blurry vision, headache, dizziness, fatigue, diarrhea, nausea, vomiting, heavy sweating, muscle or abdominal pain, tremors, lack of coordination, confusion, skin irritation, irritability, sensitivity to sound or touch, blindness, fingernail loss, nosebleeds, loss of appetite, twitching muscles, difficulty walking, talking, and concentrating, convulsions, unconsciousness, difficulty breathing, coma, and even death. (11)

Chronic health impacts include many types of cancers and neurological effects. Many years after the exposure, large numbers of people who have suffered serious acute poisoning have “significantly impaired hearing, vision, intelligence, coordination, reaction time, memory, and reasoning.” Cognitive symptoms of chronic damage to the nervous system “include personality changes, anxiety, irritability, and depression.” Fertility can be affected through damage to men’s and women’s reproductive organs, as unfortunately many have learned to their deep sorrow. Many pesticides that persist for long periods in the environment are also known to be endocrine disruptors. (11)

When pesticides are used, the US Environmental Protection Agency requires a certain amount of time to pass before workers may return to the fields. Workers have reported violations of this regulation, stating that they were ordered to pick the fruit during the safety interval.

In the United States, government estimates indicate more than 20,000 farmworkers out of 5 million or more workers in this country suffer acute pesticide poisonings per year. As for chronic impacts, no serious effort has been made to develop estimates of annual cases, because of the difficulty in linking the effects to the pesticides. At the global level, the World Health Organization estimates that three million acute pesticide poisonings occur each year, including 220,000 fatalities. (11)

One of those workers affected by pesticides was 19-year-old Francisca Herrera. She worked in fields that had recently been sprayed with mancozeb, 24 to 36 days into a pregnancy (12). Her son Carlos was born without arms or legs, a rare condition called tetra-amelia syndrome. “When you work on the plants, you smell the chemicals,” she said. “It has happened to me many times that when you are working and the chemical has dried and turned to dust that you breathe it.” (7)

Regulations require that workers use protective eyewear, gloves, rubber aprons, and vapor respirators. Herrera said she had not been warned of the dangers or advised of the protective regulations. She felt sick with nausea, dizziness, and burning eyes the entire time she worked in the field. She subsequently developed rashes and open sores.

Herrera’s boss, a subcontractor to Ag-Mart, told her that if she did not work, she would be kicked out of the room he was providing. Because of her pregnancy, she needed a place to live, so despite her illness she continued to work. Even after quitting the fields for the childbirth, she continued to hand-wash the chemical-soaked clothes of both her husband and brother.

After Carlos’ birth, he needed constant medical attention. Although by birth he was an American citizen, Herrera and her husband were undocumented and at risk of deportation. There was not much they could do for their son.

Florida surpasses most other states in its use of pesticides and toxic chemicals. For example, in 2006, Florida’s tomato farmers applied nearly eight million pounds of insecticides, fungicides, and herbicides, compared to only one million in California (7). This is likely because the conditions in Florida are not conducive to growing tomatoes, because of the lack of rich soil and also because of the high number of pests that thrive year-round in the Florida sunshine.

In 2006, the Florida Department of Health reported only two definite or probable cases of harmful pesticide exposure among its agricultural workforce of roughly 400,000 men and women. California, with only three times the number of workers, reported 200 cases. Because of the higher risk of exposure in Florida, this may be evidence of a lack of enforcement of regulations.

In both Florida and California, physicians are required to report cases of pesticide poisoning. But in Florida that law is “unenforced and ignored” (7). The director of the hospital where Herrera’s deformed baby Carlos was born said he wasn’t even aware of the regulation.

According to a 1997 report, “Indifference to Safety: Florida’s Investigation Into Pesticide Poisoning of Farmworkers,” Florida enforcement of safety regulations meant to prevent avoidable exposure and injury came up short:

· The State repeatedly failed to find a causal connection between pesticide exposure and the injuries suffered by farmworkers.

· The State found regulatory violations in 31 instances, but issued only two fines.

· The State failed to adequately investigate poisoning complaints even when a farmworker was seriously injured or killed, by systematically: failing to interview co-workers or other eyewitnesses out of the presence of supervisory personnel (with adequate translators); failing to obtain relevant medical records; routinely accepting uncorroborated employer claims of compliance; using checklists as a substitute for a thorough on-site inspection; and ignoring evidence of employer retaliation.

· The State lacked adequate investigative protocols.

· The State failed to coordinate the investigative efforts of FDACS and other enforcement agencies, such as OSHA.

· The State failed to impose meaningful penalties when pesticide violations resulted in worker injury. (13)

This indifference to worker safety on the part of the state has resulted in a corresponding indifference on the part of the landowners, who take advantage of the lack of enforcement to improve efficiency of their farming processes, at the expense of the workers.

Most cases of illness from pesticide exposure go unreported. Workers are not trained to recognize symptoms of pesticide poisoning, which can be similar to the common cold or flu. They do not have health insurance and many workers are undocumented, so they avoid visits to the doctor in any case. Many are embarrassed to be seen as weak, so continue to work through their illnesses. In many cases, they are threatened with termination if they miss work due to illness, or report being sprayed.

One example was Guadalupe Gonzales III, who arrived at work in 2005 at 7 AM, at a farm operated by Thomas Produce Company, then one of the biggest players in the Florida produce business. Gonzales did not report directly to the farm, but to a contractor, or “crew boss,” Raul Humberto Ruiz. Gonzales’ assignment that day was to apply methyl bromide.

The EPA classifies methyl bromide as a “Category I Acute Toxin,” the most deadly category. The label instructions on the chemical container read “All persons working with this fumigant must be knowledgeable about the hazards, and trained in the use of the required respirator equipment and detector devices, emergency procedures and proper use of the equipment.” Gonzales claimed that he had not received training, and was not even told the name of the pesticide, and he was wearing a short-sleeved shirt. By 11:00, his head started aching, his eyes stung, and he experienced severe chest pains. Instead of sending him to a medical facility for treatment, the crew leader told him to sit in the air-conditioned truck. After a while Gonzales felt better, so returned to work, but that evening his condition worsened, and he went to the emergency room. Two days later he returned to the fields and his symptoms returned, so he filed for worker’s compensation. He reported that his boss fired him saying, “If you keep feeling bad, I can’t keep you as part of the crew anymore.” Gonzales lost his job for following protocol. Ultimately, the state fined the company $5000, a slap in the wrist. The fine was later reduced to $3500 on appeal. (7)

Another example of this indifference to safety was Victor Grimaldi. He recalled his first day on the job: “I was taken into the office, and the first thing the boss said was, ‘Sign this!’ It was a document written in English, which I don’t read or speak, but I needed work, so what was I going to say?” Grimaldi was then shown a pesticide-handling safety video, also in English, but he was able to understand a little bit from the context of the graphics. He was given a backpack-mounted tank full of pesticide, and told to start spraying a row of tomatoes. Eventually he came to a group of pickers, so he moved around them. When the boss asked him why he moved, Grimaldi replied that he had just seen a video showing that spraying near people was against the law. “I’m the law out here,” the boss replied, and ordered Grimaldi to return to the row with the pickers.

Later that day, Grimaldi had to stand in what seemed to be water, but that night his toenails fell off in the shower, like flakes of soap. Grimaldi said that when workers complained, they lost their jobs. So workers learned to be silent about their symptoms. (7)

Is this abuse of workers an environmental justice issue?

The Stakeholders

The fact that agricultural reliance on pesticides continues to grow despite evidence of the devastation to our ecology, forces us to question why. We must examine the mechanisms of power that operate in corporations and in our national regulatory agencies, and look directly at the economic and social contexts that “grant official invisibility” to epidemic levels of poisonings, health consequences, and ecological damage. (11)

Farmworkers fear being fired or being labeled as troublemakers if they seek medical help, or take time off work to recover. According to one study, nine percent of farmers reported at least one incident serious enough to seek medical attention. The same study noted that the farmers “tended to accept this level of illness as part of the work of farming.” (11) This perplexing level of submission in the face of injury underscores the level of social disparity that exists, allowing astounding rates of occupational hazard to persist without (A): consequences to the suppliers of the pesticide products or to the subcontractors who perpetuate the lackadaisical enforcement of precautions that already exist, or (B): subsequent adoption and enforcement of regulatory measures sufficient to reduce the rate of injury.

Industry scientists, regulators, pesticide users, and public interest groups all agree that the chronic use of pesticides is a health and environmental hazard. It would be logical to think that a course of action leading away from the use of pesticides would be prudent. But somehow, this is not what is happening. Instead, excuses stack up against regulations to stall them: “They can be applied in a safe and harmless manner if instructions are followed”, they say. “Research we’ve sponsored indicates that no significant hazard exists.” “By controlling the exposure we can control the risk.” “Alternatives are not cost effective.” “We don’t know enough about the extent of harm to justify extreme measures.” “The harm done is outweighed by the economic benefits of using the pesticide…” Such claims by the chemical companies and big growers having both political and economic clout serve to perpetuate the debate endlessly in our regulatory system, resulting ultimately in an abhorrent lack of action against the use of pesticides. The first to lose are those farmworkers who experience primary exposure. The second losers are the ecosystems which are all affected by the use of pesticides. The third losers are the American consumers who are unwittingly sponsoring the use of pesticides in their food with their purchases, unaware of the health consequences not only to the workers, but also to themselves as they consume products grown in a manner that marries dangerous chemicals to their food. And who are the winners?

Six of the world’s top six chemical and seed companies, collectively known as the “Big Six”, control the first link in the corporate food chain. Business-friendly court decisions in the 1980’s opened the door to a faster rate of market concentration than any other farm input sector. The Big Six agenda promotes chemical dependence in a way that thwarts both public and private sector alternatives and innovation. Heading the list at 19% market share of agrochemical sales in 2009 is a company named Syngenta, based in Switzerland. Bayer (Germany, 17%), BASF (Germany, 11%), Monsanto (USA, 10%), Dow AgroSciences (USA, 9%), and DuPont (USA, 5%) follow close behind. The six companies enjoy a collective market share worldwide of 71%. These companies have a dangerous chokehold on the global agricultural research agenda. They determine to an astonishing degree, the priorities and future direction of agriculture research worldwide. (14) (15) According to a study prepared for the United Nations Conference on Trade and Development, there is “clear evidence suggesting a trend towards greater concentration at several stages” of the agricultural input segment. Three leading companies account for roughly half of the total market. An aspect of the convergence of the agricultural market is increased coordination, which can be interpreted as a trend towards “contractual arrangements, alliances, and tacit collusive practices” between the companies. Evidence suggests a trend towards heightened strategic cooperation among the largest competitors. Vertical coordination upward and downward along the food chain including the handling, processing, and marketing of agricultural inputs is also noted in the report. (16)

Syngenta, Monsanto, and their other chemical buddies, along with the businesses involved in the marketing of the food and products, are the big winners in the chemical war, and they laugh their way all the way to the bank.

The fact that pesticides continue to be used, promoted, and accepted in spite of the serious consequences, is a symptom of this different, more sinister kind of chronic poisoning. Economic policies that put short-term agricultural profits first at the expense of health and social concerns are gaining ground. Continuing public confusion about the extent of damage from pesticides, weak regulations and enforcement, and a lack of public investment in alternative sustainable pest management approaches that already exist, are additional symptoms of the poisonous influence of this industry. (11)

The structural changes that are unfolding in the agricultural industries up and down the food chain are subtle. They are difficult to detect because of the complexity of corporate deals that often escape public scrutiny. (16) Besides the growing monopoly of the chemical market, other key components have been instrumental in perpetuating the destructive use of pesticides.

First, the agricultural industry has worked to guarantee an oversupply of farm workers by lobbying and negotiating for labor and guest worker programs such as the Bracero Program described above. Big growers have used their political influence to have immigration restrictions loosened. They have also worked, sometimes illicitly, to recruit a steady stream of uneducated and desperately poor men and women who are vulnerable to their manipulations and thus unable to voice the horror of their predicament. It is in the growers’ best interests to ensure an oversupply of impoverished workers, because of the resulting competition among the workers and the ensuing silence of their voices for the sake of their jobs.

Further, growers have historically sought to define farmworkers as a special group of laborers who do not merit the same workplace protections or rights to organize as other American workers. When other workers were provided with basic labor protections in the 1930s (minimum wage, Social Security, unemployment insurance, the right to organize), farmworkers were specifically excluded.

Layers of contractors and subcontractors allow large companies to distance themselves from the workers they rely on. Farmworkers are forced to struggle within an informal world that is difficult to regulate because of the unnavigable layers.

The Resistance

In 1993, a small group of workers in Florida’s largest farmworker community, Immokalee, began meeting weekly in a room borrowed from a local church to discuss how to better their community and lives. They organized themselves as the “Coalition of Immokalee Workers”, or CIW. At first their efforts focused on raising wages, and later they became more activist, focusing as well on workers’ rights. By 1998 they had won industry-wide raises of 13-25%, which brought the workers’ pay back up to pre-1980 levels. But wages remained below poverty level.

In 2001, the CIW called for a Taco Bell boycott to pressure the company to take responsibility for human rights abuses in the fields of Florida. In 2005, Taco Bell finally agreed to meet the demands of CIW to improve wages and working conditions for the Florida workers in its supply chain. Later, McDonald’s and Burger King also reached agreements with CIW. Whole Foods Market, Trader Joe’s, and Subway have also followed suit. (17)

An offshoot of CIW’s successful Campaign for Fair Food, The Fair Food Standards Council opened in November 2011, and now oversees the “Fair Food Program”, which forms a new model of social accountability. Through this program, participating buyers give preference to Florida growers participating in the program, and pay a 1.5 cent premium per pound of tomatoes. The growers agree to a worker education program conducted by the CIW, agree to have compliance independently monitored, agree to pass on the price premiums to their workers, and implement a system of health and safety which affords the workers structured input into the safety of their work environment. (18) (19) Directing the program is 58-year old Laura Safer Espinoza, former New York Supreme Court justice, who came out of retirement to take on the daunting responsibility. She had moved to Florida anticipating to volunteer to help the Immokalee tomato pickers, but applied for the FFSC position instead, when she learned of the opening. “I feel it’s an honor and a privilege to be part of a moment in history when buyers and growers and workers come together to rectify an historic injustice,” she said. (20)

The case of Carlitos Candelario versus AgMart

The benefit of having such a coalition in place to provide a voice for the people is evident in the story of baby Carlos, described earlier in this paper. Had his plight occurred in isolation, his defects would have been considered an unfortunate anomaly. But incredibly, two other infants having severe deformities were born to workers in the same community, and all three babies were born within eight weeks of each other. One of the three babies died within three days. All three mothers worked for the same company, Ag-Mart Produce, Inc. Because of the migratory nature of farmworkers, it is unknown exactly how many total births occurred in the area at the time, but it is estimated that 25 live births occur per year among 191 female farmworkers that were employed in the area where the mothers worked, or two live births per month. If we consider the three-month period during which these three unfortunate infants were born, and assuming the other three estimated births during the period were healthy, that provides an incidence rate of 50%. (12) In Florida, approximately 3% of live births have major birth defects, so in contrast, the three incidences together with baby Carlos present a tragically significant case.

Andrew Yaffa is an attorney widely recognized as one of the top lawyers in the state of Florida. He learned of the plight of baby Carlos through the Coalition, and decided to take on the entire modern agricultural industry with its chemical-based philosophy in a trial that would eventually have important ramifications for agricultural workers in Florida. Instead of suing the chemical company that made the pesticide that resulted in Carlos’ deformity, Yaffa decided to depart from convention and go to battle against the corporate farm where Herrera had worked. He approached Carlos’ mother, Francisca Herrera, and promised to bear all of the legal expenses himself, and be paid only by taking a percentage of anything they won in the lawsuit.

Through tissue samples, genetics were ruled out as a cause of Carlos’ deformity, and it became an environmental issue. Dr. Omar Shafey PhD, an epidemiologist, told Yaffa that the three instances of defects within such a short period represented a cluster that could not possibly have happened by chance. Dr. J. Routt Reigart stated that in his opinion, Herrerra had been “exposed to a witch’s brew of herbicides during the early stages of her pregnancy.” (7)

Herrera and her husband, Abraham Candelario, are from Guatemala, and speak no English and very little Spanish. During the deposition in 2006, Herrera made the following points through an interpreter:

· She had gotten her job with Ag-Mart when a recruiter had come to her village and offered to take her to the company’s farms with other workers.

· She acknowledged that she had signed a document, “Chasing the Sun Training Acknowledgement”, which stated that she had watched a training video about pesticide handling. However, she had not seen the video; she just signed the papers they had given her.

· She also acknowledged that she had signed a questionnaire that had been filled out by Ricardo Davilos, an employee of the Florida Agriculture Department following Carlos’ birth. She had told Davilos that she had felt sick whenever the tomatoes were sprayed; she got headaches and earaches, and her eyes would burn. She also got a rash on her skin. What Davilos wrote on the document, however, was that “I have never been sprayed and was not made to work in a field that was sprayed.” She’d had no idea what had been written on the document she signed.

· There was enough spray to make her clothes wet with the spray. She said, “when you put your hands in the plants, immediately it sticks to you.” But she could not wear gloves because she didn’t have the money to buy them. She described being sprayed directly two or three times per week. She and other workers would try to run from the spray, but the wind would carry the spray to them anyway.

· When Herrera stayed home sick one day, her boss told her that if she didn’t come in to work she would need to move out of the house.

In 2008, nearly three years after Yaffa took on the case, they settled out of court. Ag-Mart admitted no guilt, but paid a substantial (undisclosed) sum, enough to ensure care for Carlos for the rest of his life. The money was placed in a life-care plan, overseen by a trustee who is charged with making sure the funds are used to directly support the boy. Although the agreement resulted in the success and resolution of the individual case for Carlos, it was a disappointment that the deeper and farther-reaching tangle of issues surrounding the consequences of the pesticides were left unaddressed. Still, a precedent was set that will hopefully pave the way for future cases. The silence was broken.

The Organic Movement

The question of whether pesticides are needed at all is under hot debate. Organic methods are being developed that can sustain the kind of yield capable of feeding the world, without the use of the herbicides and insecticides that present such great risk to people and our ecology. Proponents of conventional methods fear that organic methods add significant cost to the price of our food such that it would not be affordable at large-scale. Consider though that the costs of collateral damage due to conventional methods are not currently reflected in the price of the food we buy. We are paying with our tax dollars (and with our health) for damage resulting from the destruction of our soil and waterways, and for the devastating effects of toxicity to farm workers. We haven’t even begun to bear the costs of the massive cleanup efforts that will ultimately be needed, or of the enormous loss of the fossil fuels consumed by conventional methods. The consequences of the deterioration of our soil and water resources, and the long-term effects on our ecology such as global warming, will have to be faced at some point if we continue such unsustainable farming practices. Additionally, our taxes subsidize the production of certain conventionally produced crops. All of these costs are paid behind the scenes, hidden from the consumers. Those costs are significant; we cannot afford not to use organic methods.

In one astounding study whose results were just released this past summer, researchers found that low-input, high-diversity (LIHD) rotations outperformed the conventional system in yields, while surprisingly producing similar profits.

The project, conducted by Iowa State University, began ten years ago on the University’s Marsden Farm in Boone County. It compares the conventional corn-soybean system with two alternatives of three-year or four-year rotations with a cover crop. Yields from the rotation crops were actually greater on average than those using conventional methods for both corn (4% greater), and the soybeans (9%). The longer rotations reduced herbicides by 88% compared with the conventional system, with little difference in the amount of weeds observed. The freshwater toxicity resulting from the herbicides used was 200 times less in the longer rotations.

Another important finding of the study was that, in addition to the improvement in yields, profits obtained from the rotations were similar to those using conventional methods, even during the transition years, and even though labor expenses were higher. This is a significant consideration for farms that support diversification of cropland.

The results were achieved by replacing purchased chemical inputs with combinations of ecological processes, human knowledge, production management skills, and labor.

While the methods were not strictly organic in certification terms, the results show that both yield and profits comparable to or exceeding conventional methods may be obtained while minimizing the use of synthetic fertilizers, herbicides, and fossil fuels. The diverse rotations also enrich the soil, break disease and weed cycles, and diminish erosion. They protect nearby waterways from pollution and reduce the risk of creating herbicide-resistant weeds. (21) (22) (23)

This is big news, indeed. The success of this study should encourage further long-term studies for other crops that are conventionally under high use of chemicals for production, including tomatoes.

The Continuing Struggle

Efforts of the Coalition of Immokalee Workers have gone a long way to improve conditions and risks faced by the men and women of the fields. While these interventions have improved the lives of many workers and their families, they have failed to transform farm labor into a job that can provide a living wage. A farmworker’s status has become so institutionalized that the “only way to improve the lives of migrant farmworkers is by challenging the structure of our nation’s farm labor system.” (24)

The Fair Food Program won’t be sustainable unless the major grocery stores participate and reward the growers with their purchases and pay the price premium. Although Whole Foods Market and Trader Joe’s have led the way in their participation of the program, major supermarket chains including Ahold, Kroger’s, and Publix, Dominick’s, and Jewel, have yet to sign on to the program. The US Agriculture Department itself leaves an additional and conspicuous vacancy in the Fair Food Program; the Department does not participate in the program for its own school lunch program purchases. (25)

Every five years since 1949, Congress revises and reauthorizes massive agricultural legislation in what is known as the Farm Bill, which has far-reaching and significant implications not only for the farmers, but also for us as consumers, because to a large extent it determines the food we eat. Among the important provisions of the 2008 Farm Bill that are relevant to this paper is the CRP Transition Incentives Program, which provides for a transition option for beginning and socially disadvantaged farmers. Under this program, incentives are given to land owners to transition their land to organic use of the land or to make conservation improvements. Other provisions of the Bill support the growth of the local food and organic movements, including a Farmers Market Promotion Program, a National Organic Certification Cost Share Program, an Organic Agriculture Research and Extension Initiative, and a program for Outreach and Assistance to Socially Disadvantaged Farmers and Ranchers. This year Congress has worked overtime to debate the features of the next Bill, but incredibly, three weeks ago on September 30, the current bill was allowed to expire in what has been called a “Congressional Meltdown.” Congress not only failed to pass a new Farm Bill, but in an unprecedented debacle failed to pass even a short-term extension to provide ongoing legal authority. When Congress returns to its lame-duck session next month, our legislators will have to either hammer out the new Bill within a month and turn it over to the President (something they were unable to do even without lame-duck status), or extend the old Bill. If that happens, the new Congress beginning session after the first of the year will have to start all over again at square one to draft an all new Bill for 2013. This is a classic example of the kind of policy paralysis that is surrounding the deeply controversial matters of farming, and of the sticky stronghold and influence Big Agribusiness has on our legislators.

Despite all this, many independent farmers are continuing to develop alternative ecologically sustainable farming methods, sometimes at significant personal sacrifice. They are leading the way towards more widespread use of responsible techniques to fulfill their inherent stewardship of the land and to protect the workers under their employ. Those heroic farmers need the support of consumers. Additionally, more public and private funds need to be dedicated to research, and programs designed to reduce pesticide use need to be put into place. We need more than simple assurances from corporations that the fox is not in the henhouse. Independent verification and enforceable regulations will go a long way in ensuring a continuous progression towards cleaner farm practices, safer working conditions, and fair labor practices. We need to put effective mechanisms into place for targeting specific uses of hazardous chemicals, removing them from the market, and replacing them with safer approaches. Preventing the release of harmful chemicals into our environment is actually the “most effective, economical, and morally justifiable approach to safeguarding people and ecosystems from costly and sometimes irreversible damages.” (11)

The secrecy and misinformation surrounding farm practices continue to leave consumers in the dark and protect the companies who benefit; this lack of awareness remains a huge obstacle to the development of safer approaches. Big growers satiate the public’s desire for clean, healthy food by churning out advertisements proclaiming the buzzwords of the system, such as “Fresh”, “Natural”, “Healthy”, and “Pure”. Photographs of beautiful, serene farm country grace the packages of farm products and the aisles of the supermarkets to give the impression of beauty, safety, and serenity; they proclaim a subliminal message to the consumer that all is well and good at our farms. These are stalling tactics that work miracles in turning otherwise public scrutiny away from the tragic reality. The fact that these messages are sometimes partially true makes it all the more easy to swallow the myth that all is well in agriculture in our beloved free country. The lack of awareness of the true sinister scale of damage associated with conventional farming practices keeps people from challenging assumptions that we benefit more than we lose from those practices. We must address the social contexts in which massive unnecessary pesticide damages are considered “normal” and “acceptable”. Helping the American consumer to discern agricultural fact from these profitable fantasies will require a consistent and steady increase in disclosure; the voice of reality must be loud enough to match the corporate propaganda of the agri-giants. This voice of truth must be strong enough to touch the sensitivities of the public consumers. It must produce the justifiable outrage that will ultimately generate support for the change that is so desperately needed. Exposing the hidden dimensions of pesticide damage remains an urgent public and environmental health priority. (11)

Conclusion

As we are reminded by Daniel Rothenberg, “Hands touch, feel, caress, and labor, reminding us that, in the end, production is always linked to people – to their lives, struggles, and stories.” (24) The tomatoes we purchase with little thought reach our supermarkets at a great cost that is not reflected in their retail price. This cost is ultimately absorbed by farmworkers in Immokalee and other areas throughout the country, who are among the poorest of American workers. They are recruited from among the least powerful cultures and are historically denied equal protections. Because of their language difficulties, their lack of authorization in this country, and the lack of awareness of their inherent rights, they lack the ability to resist this injustice and their human rights are ignored. Through the lack of educational opportunities for their children, their poverty perpetuates from one generation to the next. The history of America’s farmworkers is a “tale of an entire class of laborers who have been repeatedly denied access to our nation’s promise that hard work will be justly rewarded.” (24)

Although the tomato industry faces problems such as perishable products and volatile weather, and although the seasonal nature of tomato crops requires workers to migrate and to work for multiple employers, there is no reason why these men and women should be our nation’s poorest laborers.

A lack of popular awareness has come about because our culture has isolated those who are more fortunate from those who are less fortunate. “The apparent invisibility of production is a form of social forgetting, a politics of glossing over the real social and economic relations that allow for our high standard of living.” (24) This state of forgetting reflects the poignant failure of our country to live up to its own ideals. We must work to restore the links in our local food systems that bring farmers and consumers together. These links represent the key to raising awareness of the issues and of the tragic abuse of those who feed us, the very abuses agri-giants would rather we don’t see. Ultimately, it is those links that may help us to heal our broken agricultural system.

Interview with Herman Brockman about GMOs

The subject of genetically modified organisms (or GMOs as they’re commonly called), is coming up more and more as people are questioning the health effects of the technology and its impact on our environment. In last week’s election, Monsanto and other major chemical, seed, and fast-food companies only narrowly defeated a grass-roots effort in California to require the labeling of GMO products, something that is already done throughout Europe and most of the developed world. Meanwhile during the same election, voters in San Juan County Washington passed a ballot initiative to ban the growing of GMOs in the county altogether. The states of Washington, Connecticut, and Minnesota are currently working on their own GMO labeling initiatives, and the movement will continue its momentum, pressuring the FDA for a national label.

Because of the increasing concern over and interest in GMOs, I decided to bop down to central Illinois last Sunday to chat with someone who has considerable insight into GMOs and genetic engineering in general, Herman Brockman. Herman is Distinguished Professor of Genetics at Illinois State University, where he was a professor and researcher for 35 years. Raised in rural Danforth as the third generation of a farm family, Herman continues to farm, working with his son Henry on a farm that provides organic produce to well over a thousand Illinois households (including mine). As a geneticist and farmer, Herman has a unique perspective about genetically engineered crops.

Herman’s daughter, Terra Brockman, also participated in the interview. Terra has worked as a teacher, writer, and editor in Japan and in New York City, and has travelled extensively. She founded an educational, non-profit organization, The Land Connection, in 2001, which is dedicated to preserving farmland, training new farmers, and connecting consumers with local producers. She is author of The Seasons on Henry’s Farm: A Year of Food and Life on a Sustainable Farm, one of three finalists for the 2010 James Beard Award in the writing and literature category.

The interview was so informative and so many compelling concepts were introduced, that I decided to write up the most salient points, preserving the interview format as much as possible. With this write-up, I invite you to share in the discussion that begins with an overview of the Green Revolution, and delves into the difficulties we face today in feeding the world. It examines GMO technology, and summarizes some of the risks posed by GMOs to our health and environment.

The Green Revolution

Mary: Norman Borlaug led the introduction of high-yield crops, and is often credited with saving over a billion people’s lives worldwide from starvation. He was awarded the Nobel Peace Prize in 1970 in recognition of this achievement, and he has been called the “Father of the Green Revolution”. Can you talk about that and how it relates to what we now refer to as GMOs?

Herman: It was, as always, a temporary technological fix.

Terra: And it was based on classical breeding.

Herman: That’s right, it had nothing to do with GMOs. That’s important. I’ll give you a real quick history.

History

Herman: The Japanese found a gene that caused dwarfing in wheat. This was significant because previously, attempts to grow wheat crops with fertilizer resulted in strains whose large grains were so heavy they would topple over as the stems were too weak to support the load. Those old strains of wheat did not grow well with fertilizer. Dwarfing was achieved with a single gene mutation. With dwarfing, instead of growing tall with thin stems, the plants were short but had thicker stems, and the new wheat crops responded enormously to fertilizer. The plants could stay upright and hold the heavier, denser grains. The crops also responded more to irrigation. They weren't what you would say intrinsically better; the improvement was only in terms of yield. So of course when they used fertilizer, particularly in those parts of the world such as India where they had not used much fertilizer before, they did get a big boost. They did the same thing in China with rice, with similar results, and it spread throughout Asia. Yes, the Green Revolution worked as a short-term technological fix. It increased the yield a lot, and fed a lot of people.

Mary: Just so I understand, the fertilization and irrigation are valid in dry climates?

Herman: Valid in terms of increased yield, yes. But here’s a book that you need to read: Full Planet, Empty Plates, by Lester R. Brown. He goes through a lot of this about the Green Revolution. The down side of course in terms of water is this: Water scarcity is all over the world. There’s a huge part of India and China and Pakistan, where they’ve been irrigating from what’s called fossil aquifers. You know about the Ogallala aquifer in Texas and Oklahoma? When it’s gone, it’s gone forever. It was deposited a long time ago; it’s not replenished from surface water. It’s the same in huge areas of China, Pakistan, and India, and they’re just about gone. In the places where they’ve been raising wheat like crazy, they won’t be able to, once the aquifers are gone. They’ve been using water for irrigation, and the water level has dropped. They keep dropping the depth of the wells, and the water keeps going down, and it’s not replenished.

But, going back to the Green Revolution, the main point, I think, is this high use of fertilizer. There are three of them of course: nitrogen, phosphate, and potassium. They are the three macro nutrients, the ones that are used in huge quantities. Phosphates come out of the ground as rock phosphate. Farmers, including my dad, would simply use the ground-up rock, spreading it on the fields. Organic farmers still occasionally use it. Because it’s not water-soluble, it’s available to the plants only very slowly. At some point they came up with this process of treating the rock phosphate with some acid, getting what they call “super phosphate”. That’s what’s sold to all the industrial farmers in this country, and is exactly what’s used over in Asia on the wheat and the rice. It’s highly water-soluble. So when farmers apply it, it’s immediately available to the plants, just like that. You get a huge response, right away, the year that you put it on. Whereas when the organic farmer puts it on, it lasts for ten years, slowly released each year.

Well, it turns out that this fertilizer still comes from those rock-phosphate deposits, from different parts of the world. Some are in the U.S.; the biggest one is in China. There are estimates as to how long those deposits will last. One estimate is I think from the Arizona State site, and you can argue about which estimate is right: 40 years. 40 years! And it’s gone, forever. There will be no more phosphate to put on the crops. The yields of corn and wheat and rice will plummet. And even before they plummet, the grains will become more expensive, and the poor countries, especially, won’t be able to afford them.

The Green Revolution was a technological fix that yes, saved a lot of people’s lives, but has not proven to be a sustainable solution to world malnutrition, hunger, and starvation. Unintended, but predictable consequences of the Green Revolution include depleted soils, declining surface and subsurface water, lost crop diversity, poisoned ecosystems, farmers indebted by the high costs of external inputs, increased rural-to-urban migration, deforestation, and increased CO2 production from the increased use of fossil fuels. A lot of people who know about these problems say scientists will solve everything; they’ll do something. I don’t know what the heck it would be in this case, but that’s what a lot of people always think.

Mary: Quick question, we have two things here. One was the rock phosphate that comes from the ground, and it’s available slowly, and you also have the industrial method, which is treated with an acid…

Herman: Some of the big companies do something with it to make it water soluble.

Mary. Oh I see, they process it in some way to make it more water soluble; that was the distinction. But they’re still using the same resource.

Herman: That’s right. And I should know the actual chemical name of it, but the jargon for it is “super phosphate”. “Super” because you get the big boost in yield, because the water soluble version is immediately available. Now, interestingly, this also means that you also get more runoff into the rivers, because it’s so highly water soluble, and you get more bloom in the Gulf of Mexico and a bigger dead zone, and more of a problem in our water sources everywhere. Again, people don’t want to look at the ecological and environmental ramifications.

Mary: There are so many things that they don’t look at, and a lot of it is because it’s hidden; it’s not easy to do it, so they’re trusting that our regulators are taking care of that so that they don’t need to. If they see a product at the store and can afford the price, then they think all is well and good. But that’s not actually the case, unfortunately.

Feeding the World

Mary: We do need to feed the world, and the population is growing. What in your opinion are the most important farming techniques that would not only be sustainable, but also result in high enough yields to “feed the world”?

Herman: A lot of international reports call the solution “agro-ecology”.

Terra: If you’re really talking about high-quality, high-nutrition food to feed a community or to feed the world, then it’s [Herman’s son] Henry’s kind of farm. As Henry says, “highly nutritious food comes from a healthy soil that is part of a healthy farm that is part of a healthy environment. This circle of health is generated by farming practices that are based on the goal of protecting and enhancing all life, from the lives of the insects, worms, and arthropods of the vegetable field to the lives of the wildlife and domesticated life who inhabit the environment around the field. On a grander scale, farming should enhance the very life of the planet by protecting a piece of it and by not polluting the planet’s water and air. The basic tenet of this kind of farming is to protect and enhance the tiny lives of the microorganisms of the soil. The teeming bacteria, fungi, and single-celled organisms are what give the soil its health and fertility. Without a healthy soil, there are no healthy plants. Without healthy plants, there are no healthy plant-eaters, be they insects or rabbits, cattle or humans. Without healthy herbivores, there are no healthy flesh-eaters either. Without healthy animals, there can be no healthy ecosystems and without healthy ecosystems, there can be no healthy planet. Synthetic fertilizer, which should be a life-promoting substance, actually deals in death. And it deals in death in many ways, polluting air and water as well as killing soil life and disrupting the soil’s intricate system for naturally providing plants with nitrogen.”[1]

Herman: Wendell Berry says a lot in his essays that a farm should come as close as it can to the way the land was before it was farmed. The first point is that there were always plants and animals. There’s no place in the world where you have an ecosystem with plants alone, or only animals. And then he goes on and talks about how you can’t completely achieve that ideal, because you’re cultivating some of it. But you can have border areas of trees and shrubs and things, and you have rotations. You use animal manure, and so on. He’s absolutely right.

Terra: And it’s important to have local adaptation. What we’re trying to do in the industrial system is completely wrong. They’re trying to use a factory model system to impose the same techniques everywhere, because that’s how a large corporation can make a lot of money, by selling the same thing every year, producing it in the same way.

Herman: But this business of feeding the world. If we really want to feed the world, we should follow all these U.N. and all the other international reports, which all say the way to do it is to help all these people, in Africa, and Asia, and so on, raise their own food in a sustainable way, not by industrial farming. They all come to the same conclusion. But the large companies can’t make money on that. They can’t sell fertilizer, they can’t sell pesticides, and they can’t sell their GMOs. But the sustainable way is the only way that will work. All those reports come to the same conclusion.

Terra: There are some good organizations that we know of that are trying to do this, trying to help with sustainable diversification, integrated ecological farming in different countries around the world. And it does work better. You can get a lot more food out of a small amount of land by doing an integrated, bio-diverse system. I have a friend who goes all around the world with an organization called Nourishing the Planet.

Herman: It’s exactly how it works for Henry. Per acre, he does much more to feed the people of Illinois, than an acre of corn or an acre of soybeans, way more! The principle that Terra just mentioned in those other countries is exactly the same! The big industrial concerns want to take all that land away from them and put it into soybeans. That won’t feed more people, it feeds less people. And a consequence of that is that there’s no place for the people to live.

Terra: Or eat, anymore. They go to cities; they live in slums.

Herman: It’s just totally misdirected. And my point is, this isn’t just my opinion, it’s in these reports that have upwards of 300 references each, of peer-reviewed papers. If all those experts, all over the world (including the U.N.), say that’s the case, I think they’re right. But companies can’t make money doing that, so they pursue their own unsustainable direction.

Mary: What about those parts of the world where the soil isn’t as fertile as what we have in the Midwest, where they have more severe problems with pests and things like that?

Herman: They still don’t have to use industrial farming.

Mary: Is there a way to improve soil that’s infertile and sandy?

Herman: Sure! It takes time, but what you do is you integrate animals and plants on the same farm. The way it was always done before was by using human waste, and the waste from animals, to get their fertility. There are parts of the world where they use legume trees to fix nitrogen. And they grow vegetable crops next to these trees. They use the leaves of the branches from some of these trees to feed a goat, to give them some milk. It’s very difficult to have a rice patch all by itself, and have it be sustainable, without commercial fertilizer. But if you have a highly diversified, integrated animal-plant community, you will be successful. That’s the way it used to be in the Midwest. Every farm had cows, sheep, pigs, chickens, trees.

Terra: With the industrial model of mono cropping, yes, you do need the fertilizers and all the other things.

Herman: The same thing is true in Illinois. There are farmers now that don’t even do corn-soybean rotation. They raise continuous corn, year after year after year. That works for them only because of the high fertilizer and pesticide inputs. Because they don’t rotate, they have a lot of fungal problems, and a lot of insects, so if they didn’t put on all that nitrogen/N-P-K, their soil fertility would become a problem, too. But again, it’s a temporary technological fix, of pouring the fertilizer and pesticides on. Even when you have some of the best soil in the world, you just keep depleting it by raising corn. The corn uses those things. The yield’s going to go down if you don’t keep putting the fertilizer on every year. Rotation solves those problems without fertilizer and pesticides.

Synthetic Biology

Mary: Herman, as a geneticist, what is your view on synthetic biology in general?

Herman: We need to use the precautionary principle here. I think you need to exercise that in every case, and give a lot of thought to it. I’m not going to say everything is bad. Probably the classic example is that of Craig Venter, who is a genius. When NIH scientists were sequencing the human genome for the first time, he came up independently with an alternative methodology, and beat them, that’s how brilliant he is. He took the bacterium with the smallest genome, the smallest number of base pairs of DNA, and sequenced it. And then instead of using the normal methods of cell duplication, he started from scratch, and re-created that same sequence using individual nucleotides. Then he inserted the result into a bacterial cell that had all the machinery for doing everything else, but had no DNA in it until he inserted the new strand. And, the cell functioned as you would expect it to. Venter now has a huge lab of hundreds of people trying to do all kinds of things, including trying to use algae to make fuel.

That knowledge opens the door to altering any strand of DNA. You can make another strand with any base pair or pairs. You can change any gene. You can quickly make hundreds if you want to, thousands, probably, of variants of that original strain. And then find out what happens to the cell as a consequence.

So that’s what I think is a prime example of synthetic biology.

GMOs are subtly different. GMO means that you are using trans-genes, a gene from a different species. Instead of using the term “genetic modification,” I prefer to talk about transgenic plants. “GMO” is a term that is established in popular literature, so it’s probably here to stay, but you need to remind people that it really means transgenic.

Genetic Modification is NOT the Same as Breeding.

Mary: I heard at a party that using GMOs is no different than breeding, it’s just faster. How would you respond to a statement like that?

Herman: Total nonsense. The first point is: there’s a transgene from a different species. In traditional breeding, you never have that.

The definition of a species is that they are a group of animals or plants that breed among themselves. Like everything in science, there are exceptions. But in general, you can’t breed across species.

Herman: The second point is the mutations. GMO researchers start with a particular variety of corn that doesn’t have a transgene in it, and they want to put, say, a Bt toxin gene in it. They start with cells, not with a plant. A long time ago, someone figured out how to derive a carrot plant on a petri plate from single cells of a carrot. It’s like human stem cells that are pluripotent. They have techniques now where you can take the cell, and under appropriate culture conditions, it will regenerate into a plant. So, they start with those cells, and put the transgene that has the Bt toxin into what they call a vector, such as a virus, or now more commonly, they just take the plain piece of DNA with the gene, and they use a gene gun to blast it through the cell membrane into the cell. One way or another they put multiple copies of the gene into the cell. The proponents say that it’s a very precise process, where the one gene just goes in. But multiple copies are inserted at random in the genome, sometimes right in the middle of a functional gene. The process is not precise at all.

Herman: Finally, the process of culturing those cells is not a normal biological situation. For reasons that no one understands exactly, hundreds to thousands of mutations occur throughout the genome, due to the process itself of making a GMO. I have never seen any pro-GMO person admit to that. Rather, they say, it’s a very precise thing, where you just take this gene and insert it in there. More and more people think that some health problems are related to GMOs. It is very seldom that random mutations will give a benefit to the organism. It’s well known by all geneticists that mutations in an organism are going to, in general, be adverse to the fitness of the organism. People that are involved in this believe that most adverse effects, if any, are coming from all of these other changes, not from the transgene itself. The process just wrecks the genome.

Mary: How is this different from the very precise methodology used by Craig Venter in his synthetic reproduction of the DNA strand? You would think that, with such technology available, more precise control would be possible.

Herman: There’s no specificity. There is a process in all cells known as genetic recombination. When you put DNA in the cell and it happens to lie next to a chromosome; basically it gets inserted by an enzyme into the chromosome by crossing over.

Terra: The impression they want to give you is that it’s a precise process, and you’ll see it on many, many websites. They try to give the impression that it’s like some surgical procedure where you insert the gene precisely in this place, and that’s just not true. But the imagery and the words that they tend to use to explain GMOs give the impression of precision. The accurate image is the one which is blasting multiple copies in with the gene gun. Some take, some don’t. . .

Herman: Then you have that cell, with a bunch of copies of the Bt gene, in the genome. The researchers culture that up and get a plant. Once you get that plant, you can propagate it, it will make seed, and you can cross it to other plants. Hundreds to thousands of mutations occur due to the insertion of the gene, and due to the entire process of making the GMO.[2]

GMO Problems

Mary: What do you think are the most serious problems associated with GMOs?

Herman: The biggest problem is the fact that GMOs have been very little studied, and even less peer-reviewed. We simply don’t know all of the ramifications! Yet GMOs are now ubiquitous in our food supply. There are tremendous risks. The classic example is the Bt toxin. When you eat Bt sweet corn, you’re eating the Bt toxin. The corn itself is an insecticide! They brag that it reduces and prevents below-ground and above-ground insects, so by definition, it’s an insecticide.

Terra: Roundup, which is an herbicide, is the whole reason we really got going with GMOs. The seed companies were able to develop soybean and corn seeds which were tolerant of Roundup. So now farmers can apply 10-12 times as much Roundup as they used to without risk of damaging the crop, and they do so in order to ensure all the weeds are killed.

Herman: That’s Round-up Ready, and they do it for everything: corn, soybeans, canola, alfalfa, even for the grasses they use on the greens of golf courses. Anything they can think of, they put that Roundup-Ready gene into it and try to sell it. Thus they make money in two ways: first, by selling the Roundup, and second, by selling the Roundup-Ready seeds.

And now, of course, as you probably already know, there are Roundup resistant weeds. This is an enormous problem, especially in cotton. In some places they’ve had to abandon planting cotton altogether, because of the weeds. There are about three species of weeds that grow up to ten feet tall with stems an inch or two in diameter, and they’re resistant. And so do you know what GMO companies have done? They now have a gene that makes the plants resistant to 2,4-D. That’s an older, very toxic herbicide that was part of Agent Orange. So now, farmers will buy this seed that is resistant to both Roundup and 2,4-D, because they can’t use just Roundup any more. The company can now charge even more for the seed, and they charge for two herbicides.

Terra: They have a patented blend now of the two, so people can buy their proprietary toxic cocktail, even more toxic now than the one by itself. 2,4-D was seldom used by farmers because it’s so toxic, but now they’re saying they must use it to combat the super weeds. It’s a vicious cycle, a chemical treadmill. As soon as you use one thing, nature adapts and continually evolves things that can resist; nature does that! Nature will always catch up in some way or another.

Herman: It’s just another technological fix. All of these things are technological fixes which ultimately fail. Phosphate fertilizer will fail because we’re going to run out. Roundup will fail because the weeds become resistant. Antibiotic use in animals in confined feeding is failing because the bacteria develop resistance. In the Green Revolution and with every one of these solutions, if you think about it long enough, you will conclude that yes, it worked for a while as a technological fix, but ultimately, it will fail. There are only so many genes they can put in for herbicide resistance, and the weeds will just keep evolving. Now they’re starting to find resistance of rootworms to the Bt toxin. Every one of those pests that the Bt toxin is toxic to will eventually evolve resistances.

Is All GMO Technology Bad?

Mary: Is there a use of GMOs that would be acceptable?

Herman: There are only two major GMOs in the U.S., the Roundup-Ready, and the Bt toxin. They keep claiming that they’re going to have drought-resistant GMOs, and GMOs with improved nutritional value. But as far as I know they haven’t come out with them.

Mary: Coming back to the synthetic biology subject, there is an example of insulin that is synthetically produced.

Terra: That’s a completely different thing than GMOs. They do try to talk about them in the same breath, and I think it should be separated. I don’t see any problem with getting insulin through genetic modification.

Herman: They simply took the human gene that makes insulin, and cloned it into a bacterium. They can grow bacteria in huge vats, producing huge amounts of the insulin. Before that, it all came from the pancreas of pigs. The insulin from the pancreas of pigs is similar, but not identical to that of humans. The insulin produced from the cloned human gene in bacteria is not just similar, but is identical to insulin made by the human pancreas. I would embrace that instantly.

Terra: It’s too bad that they do try to mix these up and say that they’re all the same, all under one umbrella, all good. But the whole agricultural system in the U.S. using GMOs is very different from what Dad just described as this different way of making insulin.

Herman: They put the human gene into the bacteria, so by definition, it’s a transgene. You have a transgenic organism in the bacteria. But the purpose is totally different; it’s not out in the environment.

Terra: It’s not polluting our well water, and air.

Herman: It’s not causing the use of more Roundup; it has nothing to do with an environmental impact of our soil, air, and water. So if there is a truly useful purpose and the GMOs are tested thoroughly for safety, perhaps they could do some good. But in agriculture, traditional plant breeding works – use that!

Mary: What about the use of GMO corn for ethanol and products (like disposable plates and cups) that are traditionally made from paper or plastic?

Herman: Feed the world, first! How much of the USDA food plate is reserved for corn products, or even corn-fed meat? Essentially nothing. The food plate is fruit and vegetables, whole-grains and protein; we ought to be growing more of those.

Terra: The point also about all these other uses for corn has been because we’ve had a surplus. I would say we could and should have recyclable paper and plastic-like products, but they should be made of something that isn’t also a food item; in other words, grass, or bamboo. It’s too bad that corn, which is a very high-calorie product that could be a good source of food for people is being made into non-food products.

Herman: They talk about feeding the world with the corn, and then we’re burning it! 90% goes to feed animals and to make ethanol. Only 10% is used for “food”.

Terra: Meaning corn syrup!

Herman: I think we need to get away from this crazy mindset that farmers should be growing more and more corn, getting higher and higher yields of corn.

Regulating Synthetic Biology

Mary: How should society approach the growth of synthetic biology? Should it be regulated, and if so, how?

Herman: Companies should have to publish their data. They currently submit it to the agencies, and it never sees the light of day. It should be submitted to journals so that it gets peer reviewed. Peer review means that the paper is sent out to at least two scientists in the field. They read it and send it back to the editor for comments. There’s a place where you say whether you reject it and you have to tell why, or accept, or accept with modification, and you tell what you think should have to be modified. Monsanto doesn’t publish in the peer reviewed journals. None of the companies that make the GMOs do that.

Concluding Recommendations About GMOs From Herman

· Follow the money: Don’t accept any non-peer-reviewed information (propaganda) from any entity that makes money, e.g. Monsanto. Or from “think tanks” etc., that they fund. In fact, now we must even be careful of universities, because Monsanto etc. have infiltrated them.

· Don’t use “traditional” agriculture or “modern” agriculture as synonyms for industrial agriculture. If any agriculture deserves the “traditional” label, it is organic.

· GMOs are one piece of industrial agriculture. If you buy into GMOs, you buy all of the unsustainability of industrial agriculture: synthetic pesticides and fertilizers, mono- or bi-culture (lack of biological diversity), poor biological health and physical structure of soil, more use of fossil fuels, more environmental contamination from pesticides and fertilizers, non-integration of crops and animals on the same farm.

· Pesticides is an umbrella term that includes insecticides, herbicides, fungicides, nematocides, bacteriacides (antibiotics), antiviral agents, rodenticides, and …

· When someone makes a claim that says GMO corn is “safe” for animal (including human) consumption, say, “Give me the peer-reviewed papers that support your statement.”

· I would restrict all discussion to peer-reviewed literature (and reviews that cite them), at least in the final analysis.
