Climate change and environmental justice: a case study in ethics and science

A key part of the fight against climate change is to reduce greenhouse gases (GHGs). So, when a massive corporation reduces their emissions by an amount equivalent to taking 900,000 cars off the road, we should celebrate their efforts in “breaking sustainability barriers” – right? Shouldn’t we nudge other companies to follow their lead? In an era where our government is denying climate change, why wouldn’t we embrace our climate allies in the business world?

A report was recently released about how Smithfield Foods is meeting its pledge to reduce GHGs. Since 2013, Smithfield has worked in partnership with the Environmental Defense Fund (EDF), a nonprofit at the forefront of environmental sustainability. As the EDF attests, it is true that Smithfield is leading other food industries in cutting GHGs. Yet it is also true that Smithfield continues to extort marginalized communities here in North Carolina.

In this article, I use the case of Smithfield Foods to ask broader questions about ethics and advocacy. I challenge my fellow scientists to consider how power is distributed between industry, academia and communities compared to how it should be distributed. Before we follow the EDF and hold Smithfield up as a role model, we must ask ourselves: if we’re only focused on reducing GHGs, on whose backs are we fighting climate change?

Smithfield Foods

The bacon on your BLT, the pork in your sausage and the carnitas in your taco likely all come from the same source: Smithfield. The scope of their business is massive, and in 2013 they were acquired by a Chinese company, WH Group. Smithfield is both the world’s largest hog producer and pork processor, which means that they raise and slaughter pigs and package meat for distribution. In 2017 alone, global sales exceeded $15 billion. In North Carolina, Smithfield owns 225 hog farms and contracts 1,200 of the state’s 2,200 hog farms (altogether this accounts for 90 percent of North Carolina’s hog production).

Smithfield hog farms are Consolidated Animal Feeding Operations (CAFOs), where hogs are raised in large barns where they eat, sleep and defecate. The shift from pastures to CAFOs has been a seismic shift in North Carolina’s hog industry. In 1974, there were 22,975 hog farms and 1.4 million hogs in North Carolina. Today, there are 2,200 hog farms and over 9 million hogs. All of those hogs need to eat a tremendous amount of grain, which they then digest to produce a tremendous amount of waste. To put “tremendous” in perspective, consider that there are 10.3 million people in North Carolina. Imagine that each person weighed between 300 to 700 pounds, and that these giant North Carolinians lived almost exclusively in three counties. Now imagine that the volume of waste produced by these animals was stored in uncovered, football field-sized pits.

Hogs and Environmental Justice in North Carolina

If you didn’t know your pork chops came from Smithfield, you may have heard about them in the news. Smithfield has been heavily criticized for its waste management practices, which were brought to national attention last year due to a series of nuisance lawsuit settlements and contamination caused by hurricane-related flooding. Stick with me in this section – the injustices perpetrated by Smithfield run deep, but this understanding is necessary to engage with the ethics questions at the end.

The waste management practices in question involve the contamination of lagoons and sprayfields, which have been the focus of most environmental justice organizing against Smithfield. In an industrial hog operation, barns are constructed so that waste falls through holes in the floor and then is periodically flushed out into outdoor waste lagoons. As of January 2018, North Carolina’s Department of Environmental Quality (DEQ) had issued hog farms permits for the operation of over 3,700 waste lagoons. When the lagoons become full, liquid waste is sprayed on to nearby fields. As you can imagine, this leads to a number of problems: the build up of nutrients and metals in the lagoon water contaminates nearby groundwater and surface water through lagoon leakage or spraying; methane, hydrogen sulfide and nitrous oxides are released as the organics in the lagoon water decomposes; the risk of lagoon flooding during storms increases; and spraying  aerosolizes fecal water. The odor and pollution impact people’s health and quality of life. Although DEQ waste permits specify when, where, and how much lagoon waste can be sprayed, the process is self-regulated and frequently violated by hog farms. Besides waste management, neighboring communities are also affected by the use of antibiotics in animal feed, pollution from the storage of dead pig carcasses, and heavy truck traffic.

What makes this environmental pollution an issue of environmental justice? According to the US Department of Energy, environmental justice ensures that “no population bears a disproportionate share of negative environmental consequences” and that historically marginalized populations have a seat at the table when environmental decisions are to be made. Hog operations, however, disproportionately affect low-income communities of color. In North Carolina, African Americans, Latinos, and Native Americans are 1.4, 1.26, and 2.39 times as likely, respectively, to live within three miles of at least one hog operation. In total, an estimated 1 million North Carolinians live within three miles of hog operation, and over half of them live within three miles of two or more. In fact, about 16,000 residents live within only half a mile of 2 – 5 industrial hog operations [reference: public comment submitted by UNC faculty and students regarding the renewal of NC’s animal operations general permit]. A recent study found that residents living near industrial hog operations had a higher risk of infant mortality and low birth weights as well as higher risk of adult mortality from anemia, kidney disease, tuberculosis, and blood bacterial infections as compared to communities of similar demographics.

Civil rights groups have taken two legal strategies to advocate for these communities. First, in 2013, 600 residents filed 26 lawsuits against Murphy-Brown LLC, the subsidiary of Smithfield that produces the majority of Smithfield’s pork in North Carolina. This started a series of retaliatory steps by Smithfield and its allies in the North Carolina legislature. Immediately after the lawsuits were filed, the General Assembly made it more difficult to file nuisance lawsuits against agriculture (Right to Farm Act). In 2017, the General Assembly passed HB 467, limiting the total compensatory damages that can be awarded in nuisance lawsuits. HB 467 was sponsored by Representative Jimmy Dixon from Duplin County, which is home to over 500 industrial hog operations. In 2018, after the first trial ended and a jury awarded the plaintiffs $51 million, the General Assembly passed SB 711 by Senator Brent Jackson and Rep. Dixon, both of whom receive contributions directly from Smithfield or from political organizations funded by Smithfield. SB 711 further limits when a nuisance lawsuit can be filed as well as when punitive damages can be awarded. Both HB 467 and SB 711 were passed over Governor Roy Cooper’s veto. In the three cases settled in 2018, plaintiffs were awarded $51 million, $25 million, and a historic $473.5 million in damages, but these were reduced to $630,000, $3.2 million and $118 million, respectively, due to HB 467 and SB 711. An additional two cases have been settled, both finding Smithfield Foods at fault. Although plaintiffs were suing Murphy-Brown and not individual farmers, Smithfield chose to remove hogs from the specific farms involved in each of the three settled lawsuits, putting the hog farmers out of business. Smithfield has successfully framed nuisance lawsuits not as a right of property owners, but as an attack on farming families. Since hog farmers tend to be white and the plaintiffs are mostly people of color, this has flared tensions along racial lines.

Civil rights groups have used another legal tool: appealing to the Environmental Protection Agency (EPA) to fight the North Carolina Department of Environmental Quality (DEQ). In 2014, the Waterkeeper Alliance, North Carolina Environmental Justice Network (NCEJN) and Rural Empowerment Association for Community Help (REACH) filed a complaint with the EPA that the DEQ was violating Title VI of the Civil Rights Act of 1964, which prohibits entities receiving federal funding from acting in ways that disproportionately harm communities of color. As mentioned previously, the DEQ grants permits to hog operations so they can have waste lagoons that, in turn, harm neighboring communities of color. Former North Carolina Governor Patrick McCroy had disregarded public requests to account for the racial and ethnic impacts of the hog industry when issuing waste permits. Under his tenure, civil rights groups attempted to negotiate with DEQ over the Title VI violation, but civil rights organizations were subject to intimidation by the hog industry. However, under Governor Roy Cooper, the DEQ has cooperated with the EPA and formed an Environmental Justice and Equity Advisory Board. As part of the settlement, DEQ will be more transparent about how it investigates animal waste complaints.

Finally, it is worth noting that Smithfield’s business practices do not only negatively impact neighboring communities, but the farmers themselves. Contract farming is responsible for 81% of hog production for Smithfield. In these contracts, farmers supply labor and equipment and are responsible for waste disposal (the part of the business that costs money), but Smithfield owns the feed and the pigs (the part of the business that makes money). This arrangement puts contract farmers in a financially difficult situation. The debt they face after constructing facilities keeps them vulnerable to their terms of contract and they are not left with sufficient resources to upgrade their facilities beyond what Smithfield requires. Furthermore, Smithfield controls almost every part of the supply chain in eastern North Carolina, from the distribution of grain-based feed supply to pork processing plants, a process called vertical integration. This means that even if a farmer wanted to break a contract and convert their land to a smaller hog farm, they would be operating in a place without easy access to feed or processing plants to support their business.

Didn’t the EDF say there was good news? Smithfield’s Sustainability Goals

In 2010, Walmart approached 15 of their major suppliers to lower their GHG emissions (an initiative which they renewed with their 2017 Gigaton Challenge to reduce emissions among suppliers). As a result, in 2013, Smithfield partnered with the Environmental Defense Fund to reduce emissions, largely by reducing fertilizer loss from grain production. The details of their progress were published in the case study mentioned earlier. Indeed, Smithfield has met their target for reducing GHG emissions from grain farms and feed milling, and has supported the majority of farmers from which they source  to adopt more sustainable fertilizer practices.

However, the case study points out that while 19% of Smithfield’s GHG emissions came from grain farms in 2018, 43% came from manure management. This refers to the methane and nitrous oxides given off by open waste lagoons. Smithfield is now turning towards biogas technology to address this issue, which captures methane and other gases and refines them into natural gas that can be used for energy. Biogas is a promising technology for curbing emissions, creating jobs, and providing renewable energy for North Carolina. However, Smithfield’s current plans do not involve community advocates nor do they ensure that their waste management practices will comply with environmental standards set by the North Carolina General Assembly in 2007 for new hog operations. Waste will still be pumped into lagoons that may pollute groundwater or be prone to overflow in storms, and effluent will still be sprayed on to neighboring fields. Smithfield has yet to include host community benefit agreements as part of their plan.      

The EDF and Smithfield have a clear strategy for environmental issues: make progress by putting aside differences and focus on common ground. This led to the successful reduction of GHGs through supporting grain farmers. This strategy seems pragmatic. However, after six years of partnership, at what point is pragmatism a euphemism for complicity?

Advocacy and hard questions

This case study illustrates how systems and sociopolitical context influence the way the scientific challenges of our day, like climate change and environmental justice, are tackled. Smithfield is an example of a powerful corporation both making meaningful contributions to fighting climate change through reductions in GHGs, while at the same time polluting the environment and investing heavily in the perpetuation of environmental injustice.

Yet if Smithfield can pay for lawyers to fight nuisance cases, buy the influence of North Carolina representatives, and support monarch butterfly preservation, they certainly can afford to compensate communities suffering from their hog operations and remediate the damage they have caused. And if the Environmental Defense Fund is truly committed to their mission of protecting our climate and human health and truly values ethical action, they should be transparent about the injustices Smithfield still has to right.

There are three main calls-to-action I would like to put forth.

1: Learn from communities. If you conduct research in a field related to identifying and treating hazards, recognize the expertise of communities affected by these hazards and learn how to support community organizing. Community-based participatory research (CBPR) is a method that involves the community in every step of the research process, using their lived experience to drive research questions, collect data and interpret results. In this way, CBPR transforms “research from a top-down, expert-driven process into one of co-learning and co-production.” For example, when UNC’s Dr. Steve Wing investigated the health effects of living near hog operations in North Carolina, the project was a result of working with community members rather than simply in communities. Through their lived experience, community members best understood the kinds of healths effects of living near CAFOs, the relationships between different community members, and the relationship between Smithfield and contract farmers. When results were published, community partners were included as coauthors. Even if findings are not published, communities can use them as evidence when pushing for change, such as submitting public comments to local government or in court.

If your research is relevant to community health, how do you engage communities? Do you value their expertise? Are they involved in research design? Do you invest time into building trust and relationships? Do you compensate community members for their time? Do you present or disseminate results in a way that’s accessible, relevant and empowering for communities?

As an aside, if you follow no other link in this article, I urge you to read more about the late Dr. Wing here or here.

2: Be an engaged scientist. CBPR is most common in the health and environmental sciences, and not all STEM fields lend themselves to community engagement. For example, understanding the chemical bonds in tertiary protein structure or figuring out how to travel to Alpha Centauri  are scientific endeavors that expand our knowledge of how the world works. We do them because, as Mae Jemison has said, “pursuing an extraordinary tomorrow builds a better today.”

However, there are still ways to be an advocate in science, regardless of your field. Be aware that every stage of the scientific process is influenced by the politics of scientists, funders and institutions: the questions to be answered, the datasets to be used, the solutions that are offered and the way solutions are evaluated. This reality reflects the importance for diverse perspectives, both by increasing representation from marginalized communities within the scientific community as well as developing equal partnerships with communities themselves.

In addition, be vigilant against the influence of special interests in science. Advocate for a democratic scientific process in the institutions you work in. Unfortunately, the publication and dissemination of scientific findings are vulnerable to industry and political pressures. Recently we have seen this at the EPA with climate change. At UNC, Dr. Steve Wing’s documents were seized by North Carolina’s Pork Council, a special interest group funded by Smithfield.

How can science advance the public good when research is increasingly privately funded? Is any of your institution’s funding tied to special interest groups, and does this give science a lack of power? How can an academic best partner with community organizers to advocate for change, when institutions may have mixed support for more progressive and political causes? Is there an equal sharing of power between your research institution and communities?

3: Be an engaged citizen.  Show up to fight for a more equitable and sustainable future.

There are some individual actions you can take. Voting is one. In North Carolina, Governor Cooper unsuccessfully tried to veto HB 467 and SB 711, two pieces of legislation mentioned earlier that have dismantled community power, making it harder to file nuisance lawsuits and reducing the compensation plaintiffs can receive. Governor Cooper will be up for reelection in 2020, and many of his potential opponents receive contributions from Smithfield and  plan to use his support for HB 467 and SB 711 against him. You can also buy pork products from small, sustainable farms, such as Cane Creek Farms in Saxapahaw.

Unfortunately, in a gerrymandered state, your vote is not enough. In a consolidated food system, with large corporations like Smithfield, buying local is not enough. We must advocate for systems changes. Fighting climate change or environmental injustice both require a combination of public education, political legislation and engaged corporations.

As Dr. Wing advocated, “we need to insist that industrial producers pay for their damages to human health and the environment.” The most important direct action you can take is to aid organizations that uplift the voices of affected community members, through donations or volunteering. We must support their efforts to raise awareness of their issue, to lobby political leaders for increased regulation and enforcement and to negotiate with corporations. In the case of Smithfield, you can support NCEJN or REACH. If you are financially able, you can donate. You can also volunteer your time.

How else can you advocate for communities and support their right to self-determination? How can we work to make systems changes while up against corporations with large lobbies? And in pursuing a career in science where objectivity is valued, in a world where future employers in academia or industry will google who you are, are you willing to speak truth to power as a citizen to demand systems change?

I don’t pose these as rhetorical questions. I would love to hear what you think. Please leave comments! Or email me, at amlacko@ad.unc.edu

My Scientific Training Brought Me to My New Favorite Book Genre

‘Tis the season of failed New Year’s resolutions

It was about this time last year that I found myself falling flat on the admirable New Year’s resolutions I had set. My daily yoga routine had evolved into a 30 second toe-touch in the morning and my new eco-friendly products were still in a shopping list on Amazon. As a 4th year graduate student all too familiar with failed experiments, I couldn’t stomach an unsuccessful project at home as well. Luckily, pursuing a PhD comes with strong problem solving skill sets. What is Step 1 of The Scientist’s Plan of Attack when faced with a problem? Turn to the literature to see if a solution has already been found. This is how I found myself in the societally constructed land where sad, desperate singles with three too many cats hang out: the self-help aisle at the bookstore.

Rather than using SciFinder to tease out quality sources, I turned to Goodreads to sort through books that could help troubleshoot my failed resolutions. My first self-help purchase was “The Willpower Instinct” written by Kelly McGonigal, a health psychologist. Professor McGonigal (Harry Potter fans rejoice) wrote the book based on a course she taught at Stanford about the science of willpower. After a few years of teaching and feedback from her students, she wrote this book outlining the currently accepted research associated with willpower, peppered in with some anecdotes from her students and how they applied the conclusions from these published studies to their own habits. Between the author’s credentials, solid reviews, and over 20 pages of references in the back of the book, this seemed like a good place to start.

It’s a year later, and I am now one of those people that goes around flinging self-help book recommendations to anyone who mentions a personal problem they’re having and constantly saying things like “this book changed my life”. But… this book changed my life.

“Self-Help” has taken on such a negative connotation that many bookstores re-brand these aisles with names such as “Personal Growth”

McGonigal walks us through a series of published rat and human studies that identifies two separate parts of the brain that either experience anticipation of a reward or the pleasure from the reward itself. In other words, while the anticipation of binging Netflix sure feels more rewarding than anticipating 20 minutes of yoga, this book taught me to pay attention to how much pleasure each activity actually brought me. I immediately found that I felt happier and less anxious during and after yoga, while watching TV left me feeling less refreshed. After learning to be mindful of what I was anticipating versus actually enjoying, I had a better shot at ignoring the distracting anticipation of a television reward.

I also learned that I was using what psychologists call “moral licensing” to give myself permission to not adapt green habits because of the little things I did, like making a saved shopping list on Amazon or sharing articles on social media. She cites many studies demonstrating the ways consumers use small green actions to assuage their guilt for participating in more harmful behaviors. After realizing what I was doing, I took concrete steps to switch to reusable grocery bags and decline plastic straws at restaurants. However, I wouldn’t let that give me permission to make more wasteful decisions later in the day.

My new identity as a self-help book reader is a year old and I am still learning new cheat codes to navigating adult life with each addition to my library. However, the stigma of the genre makes my recommendations for others often fall on the ears of unwilling readers. My 2019 New Year’s resolution? Convince you, the reader, that this genre deserves a re-brand and a chance. As scientists we are trained to find reputable sources of information, and as graduate students we have a remarkably high chance of suffering from mental illnesses. Let’s use our skill set to find quality self-help books to add to our artillery of problem solving tactics that can be applied to ease some of these stresses that make it home with us after a long day in the lab. I hope to one day walk into the self-help aisle and see lonely, desperate singles with three too many cats and any other person who wants to be a proactive researcher and peruse the literature to find personal solutions to any minor problems they find themselves needing better resources to solve.
