Letter to the EPA: Take action on “Devil’s bargain” pesticides

An Open Letter to: Michael Regan, Administrator; Michal Freedhoff, Assistant Administrator, Office of Chemical Safety and Pollution Prevention; and Ed Messina, Office of Pesticide Programs Director, Environmental Protection Agency

The environment needs protection from neonicotinoid-coated pesticidal seeds, which are by far the greatest single insecticide application across the country, covering more than 100 million acres. Fundamental ecosystem integrity, plus the welfare of millions of birds and other animals where the coated seeds are planted, are at risk. You can be the difference makers if you seize the opportunity.

You know, as we NGO-types have recited to you in the past through broadly-supported letters and petitions, that a major body of evidence now shows neonic-coated seeds are the Devil’s bargain. While there may be some effective uses, they are mostly used prophylactically with no assessment of need. And yet they do great harm to essential pollinators, beneficial insects, and farmland birds, while contaminating the environment with their toxins.

In Ontario, Canada, when farmers were compelled to prove they needed to use neonic-coated seeds before being allowed by the provincial government, their use declined by a huge margin with no adverse economic effect.

Neonics have largely been banned in Europe since 2015. But, in the US, their excess production as a result of your agency’s leniency is a waste that resulted in the ongoing tragedy in Mead, Nebraska, where AltEn gathered about 80,000 tons of unwanted neonic-coated seeds in order to distill them for ethanol but instead ending up contaminating the environment to the tune of roughly $100 million in total damages. EPA’s uncritical approval of these seeds enabled the Mead disaster.

Of all the environmental threats in the United States, pesticides are conceptually the easiest to prevent because all the approved products out there resulted from registrations by your agency. But I am not asking you to cancel registrations, I am just asking you to take a closer look at EPA’s interpretation and regulatory issues that have allowed the harms of neonic-coated seeds to spin out of control.

As US pushes “climate-smart” agriculture, hopes and fears collide

By Keith Schneider

For decades, leading US farm leaders have likened efforts to rein in harmful climate change as attacks on agriculture itself, aligning with oil and gas industry groups to block policies aimed at reducing greenhouse gas emissions.

That stance has slowly been shifting in recent years, and now, fueled by $3.1 billion in federal grants, farm country is poised to shape a new era of “climate-smart” agricultural practices and take a significant role in addressing the dire consequences of a warming planet.

The actions can’t come fast enough. A panel of international scientists warned this month that the world faces a “rapidly closing window of opportunity to secure a liveable and sustainable future,” and that the actions implemented over the next few years will have consequences “now and for thousands of years.”

The Biden Administration’s focus on agriculture is just one part of a larger effort to address climate change, but it is a key element. By funding 141 experimental projects, the administration is hoping to push an industry currently responsible for generating 10% of U.S. greenhouse gases, to the front of the nation’s work to reduce carbon emissions.

The first grants from the US Department of Agriculture (USDA), for 70 large projects, were awarded in September. A second round of funding, for 71 smaller projects, was awarded in December.

The scope of the climate-smart program is expansive. Grants range from $271,200 to teach climate-friendly practices to immigrant farmers in Iowa to $95 million to encourage grain farmers in 12 Midwest states to use cultivation methods that build soil fertility. In between are projects to expand organic and sustainable agriculture, sequester carbon on pastures where livestock graze, and develop carbon-reducing cultivation methods on farms operated by African Americans and Native Americans.

In all, more than 60,000 farms and 25 million acres of crop and rangeland are involved, with spending reaching all 50 states and Puerto Rico, according to the USDA..

Considerable sums are also earmarked for development of scientific methods to effectively measure whether these climate-smart practices actually meet a program goal of sequestering 60 million metric tons of carbon.

When making the rounds at annual farm conferences across the country over the winter, Agriculture Secretary Tom Vilsack repeatedly declared that a “transformational” new era had opened for U.S. agriculture.

Grant recipients such as Marbleseed, a Wisconsin nonprofit that trains farmers in organic agriculture, say the government support is long overdue. Marbleseed is part of a partnership receiving a $4.5 million, five-year grant to train farmer in 14 Midwest and southern states on how to improve soil fertility.

“We’ve been a tiny voice shouting into the storm for a very long time,” said Tom Manley, Marbleseed program director. “They finally are starting to hear us.”

Scientists warn pesticide impacts may be worse than we thought

In California, regulators have rolled out a plan to eliminate “high-risk” pesticides from agricultural and urban use. In Mexico, officials have announced a ban on the widely used weedkiller glyphosate. And in Canada, regulators have implemented some new pesticide restrictions and are reviewing the potential for others.

The moves, which are also playing out in various forms around the United States, have drawn opposition from chemical and farm industry forces. But supporters say they don’t go far enough to adequately protect human and environmental health.

Three University of British Columbia researchers recently published a paper that summarizes what they say is a growing body of evidence showing that pesticides are having harmful ecological impacts beyond what is already well understood, and that these impacts are not being recognized by current testing and regulations. The authors of the paper looked at dozens of studies to draw their conclusions.

The New Lede had a conversation with lead author Risa Sargent about the team’s findings. Sargent is an associate professor of applied biology within the Faculty of Land and Food Systems at the University of British Columbia. She and colleagues reviewed studies from around the world, finding alarming results.

Guest Column: Paraquat and the deliberate production of ignorance

By E. Ray Dorsey, M.D., and Amit Ray, Ph.D

Nearly 60 years ago, a chemical company found that skin exposure to very high doses of its weedkiller paraquat caused “weakness and incoordination” in rabbits. Large amounts of the herbicide, which is used on corn, cotton, and vineyards, caused some mice and rats in its labs to develop a stiff gait or tremors. A decade later, an autopsy of a farm worker exposed to paraquat showed “degenerative change” in the “cells of the substantia nigra,” a pathological hallmark of Parkinson’s disease.

Rather than remove this dangerous chemical from the market or develop a safer alternative, the company doubled down on its “blockbuster” product and sought to expand its use. Along the way, the company appeared to use techniques to underestimate the toxic effects of the chemical, hide the results of its own research from regulatory authorities, and discredit the research of an academic investigator and prevent her from serving on a U.S. Environmental Protection Agency (EPA) advisory panel.

The company’s alleged efforts seem to have worked brilliantly. Despite numerous animal and epidemiological studies linking the environmental toxicant to Parkinson’s disease, paraquat’s use in the United States from 2013 to 2018 more than doubled. As pesticides can contaminate drinking water and pollute the air their harmful effects are not limited to farmers but extend (at least) to other rural residents who also have a higher risk of developing Parkinson’s disease. Because of its health risks, over 30 countries—including China—have banned paraquat. Yet in 2021 the EPA reauthorized its use even though its own website says, “One Sip Can Kill.”

California researchers link popular weedkiller to health problems in young adults

By Carey Gillam

Children exposed to a weedkiller commonly used in farming, as well as on residential yards and school playgrounds, appear to be at increased risk for liver inflammation and metabolic disorders in young adulthood and more serious diseases later in life, according to a study published Wednesday in the journal Environmental Health Perspectives.

The research, which was conducted by several California scientists and health researchers, including from the University of California, Berkeley School of Public Health, is the latest of many studies linking glyphosate herbicide to human health problems.

Glyphosate is better known as the active ingredient in Monsanto’s Roundup products as well as scores of other weedkilling brands sold around the world. The chemical is considered the most widely used herbicide in history, and residues are commonly present in food and water, as well as in human urine.

Monsanto and Bayer AG, which bought Monsanto in 2018, maintain that Roundup and other glyphosate-based herbicides are safe when used as directed, and say the weight of scientific evidence demonstrates that safety. But more than 100,000 people in the US have alleged exposure to the weedkiller caused them to develop non-Hodgkin lymphoma. Many independent scientific studies have linked glyphosate to cancers as well as liver disease, endocrine disruption and other health problems.

In the new study, researchers tracked 480 “mother-and-child duos” who live in the Salinas Valley of California, a key agricultural area, analyzing levels of glyphosate weed killer used in the area and levels of the weedkiller present in the urine of the mothers while they were pregnant and in the children as they grew. They also took into account levels of a degradation product of glyphosate known as AMPA in the urine of the study subjects. The researchers then assessed the liver and metabolic health of the children at the age of 18.

They concluded that higher levels of glyphosate residue and AMPA in urine in childhood and adolescence were associated with higher risk of liver inflammation and metabolic disorders in young adulthood. In addition, they found that agricultural use of glyphosate near participants’ homes from birth and up through age five was associated with metabolic disorders at age 18. Metabolic disorders in youth can lead to heart disease, stroke, type 2 diabetes, and liver disease later in life.

Both metabolic problems and liver disorders are increasing among children and young adults, according to the study.

“A national scandal” – new US climate funding could make water pollution worse

By Keith Schneider

The $369 billion Inflation Reduction Act was applauded by a chorus of US organizations and activists enthusiastic about the generous funding earmarked for projects designed to mitigate harmful climate change and improve environmental health.

But some researchers and activists are raising concerns that several provisions of the new law will actually worsen a growing environmental disaster in the nation’s heartland by increasing the tide of farm-related pollution washing into waterways and groundwater.

The sweeping new statute, which includes more than $140 billion in incentives designed to promote renewable fuels and cleaner electricity generation, aims to slash greenhouse gas emissions 40% below 2005 levels by the end of the decade. But in its efforts to promote climate-friendly agriculture, it also promotes corn-fed ethanol refineries and manure-based energy production that could unintentionally supercharge fertilizer and fecal contamination.

The Great Lakes and Midwest regions face nothing short of a water quality emergency, say those on the frontlines. Farming-related contaminants have already fouled thousands of drinking water wells from Minnesota to Missouri, and virtually every waterway in Iowa is degraded with little regulation to rein in the pollutants.

“It’s already a national emergency and a national scandal,” said Emma Schmit, senior organizer in the Midwest for Food and Water Watch, an environmental advocacy group. “When we test our waterways, the main pollutants are E.coli and nitrates and phosphorus from agriculture. These are pathogens and contaminants that can cause serious issues for people. We’re about to give large corporate farms carte blanche to make it worse.”

New US research finds “worrying” evidence linking Monsanto weedkiller to cancer

By Carey Gillam

New research by top US government scientists has found that people exposed to the widely used weed killing chemical glyphosate have biomarkers in their urine linked to the development of cancer and other diseases.

The study, published last week in the Journal of the National Cancer Institute, measured glyphosate levels in the urine of farmers and other study participants and determined that the presence of the pesticide was associated with signs of a reaction in the body called oxidative stress, a condition that causes damage to DNA. Oxidative stress is considered by health experts as a key characteristic of carcinogens.

The authors of the paper – 10 scientists with the National Institutes of Health and two from the Centers for Disease Control and Prevention (CDC) – concluded that their study “contributes to the weight of evidence supporting an association between glyphosate exposure and oxidative stress in humans.” They also noted that “accumulating evidence supports the role of oxidative stress in the pathogenesis of hematologic cancers,” such as lymphoma, myeloma and leukemia.

“Oxidative stress is not something you want to have,” said Linda Birnbaum, a toxicologist and former director of the National Institute for Environmental Health Sciences. “This study increases our understanding that glyphosate has the potential to cause cancer.”

The study findings come after the CDC reported last year that more than 80% of urine samples drawn from children and adults contained glyphosate. The CDC reported that out of 2,310 urine samples taken from a group of Americans intended to be representative of the US population, 1,885 were laced with detectable traces of glyphosate.

Glyphosate is the most heavily applied herbicide in history, both in the US and globally. One of the best-known glyphosate-based products is Monsanto’s Roundup weedkiller. Roundup has been used by farmers as well as consumers for more than 40 years. Monsanto has always assured the public and regulators that exposure to the weed killer does not pose a threat to human health, but many independent scientists say there is a wealth of evidence to contradict those assurances.

People are exposed to glyphosate by using products made with the chemical and also by eating food and drinking water contaminated with the pesticide. Scientists have found glyphosate residues in an array of popular foods and in waterways across the US.

Notably, in the new paper, the NIH and CDC scientists said that while their study focused on farmers who were exposed to glyphosate when they sprayed it on fields, they saw similar results in “non-farmers.”

The findings suggest “these effects may apply more broadly to the general population who are primarily exposed through ingestion of contaminated food and water or residential applications,” the study authors wrote.

The study is so significant that it warrants regulatory attention, said some independent scientists.

“This is a top level team of investigators and a highly credible study to which regulators need to pay attention,” said Phil Landrigan, a pediatrician and epidemiologist who worked for years at the CDC and the Environmental Protection Agency (EPA) and now directs the Program for Global Public Health and the Common Good at Boston College.

Michael Antoniou, a scientist with the department of medical and molecular genetics at King’s College in London who has been researching glyphosate for years, said the results were “worrying,” with “major health implications.”

Interview: “Transformational change” is needed as severe climate change impacts loom

By Pam Strayer

Last month, Cornell University professor Rachel Bezner Kerr traveled to Egypt where she addressed scientists and political leaders gathered from around the world at the 27th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 27).

Bezner Kerr is a co-director of graduate studies for Cornell’s Department of Global Development and one of the three lead coordinating authors of a chapter about food, fiber and “other ecosystem products” for the United Nations Intergovernmental Panel on Climate Change (IPCC) report. Bezner Kerr believes that time is running out when it comes to options for preventing severe climate change impacts on people and nature.

Among her observations, Bezner Kerr is calling for a systemic transformation across the agricultural industry, which is responsible for approximately 33% of carbon emissions, including those associated with nitrogen-based fertilizers.

The New Lede (TNL) spoke with Bezner Kerr upon her return from COP 27 about her views on how and why a food system transformation is needed for climate resilience. The following is an edited and condensed account of the conversation:

TNL: When we think of climate change, why do we also need to think about a sweeping change to our current agricultural system?

Bezner Kerr: That is a key message coming out of the IPCC report–that we need transformational change and for multiple reasons. One, in terms of the food system, right now the way we produce food is heavily reliant on fossil fuels. It’s not something that you can just address one component and then your food system is set.

Amid calls for ban on weed killer linked to Parkinson’s, a battle over science

By Carey Gillam

When US regulators issued a 2019 assessment of the widely used farm chemical paraquat, they determined that even though multiple scientific studies linked the chemical to Parkinson’s disease, that work was outweighed by other studies that did not find such links. Overall, the weight of scientific evidence was “insufficient” to prove paraquat causes the brain disease, officials with the US Environmental Protection Agency (EPA) declared.

The EPA reiterated its assessment in a 2021 report. The agency said after extensive analysis of numerous factors, including concerns about Parkinson’s risk, it determined farmers could safely continue to apply the weed killer across millions of US acres to help in the production of soybeans, corn, cotton and an array of other crops.

The determination has been significant for Syngenta, the longtime maker of paraquat weed killers. The company is facing calls in the US for a paraquat ban, as well as more than 2,000 legal claims brought by farmers and others alleging they developed Parkinson’s disease because of their exposure to paraquat.

Syngenta cites the EPA assessment of the science on paraquat in defense of the pesticide, and says scientific research “does not support” a causal relationship between the chemical and the disease. On a Syngenta-run paraquat information website, the company highlights several studies it says also backs that position, including many conducted by company scientists or by outside scientists who received company funding for their work.

Last week the Guardian and The New Lede reported that internal corporate records show Syngenta had knowledge of science linking paraquat to Parkinson’s decades ago but sought both to refute the evidence with various secret tactics. The documents are available at the Paraquat Papers Media Library.

US farmworker, health and environmental advocacy groups say in contrast to the corporate science, research conducted by independent scientists provides abundant evidence of paraquat’s ability to cause Parkinson’s and other health dangers, and the EPA is improperly discounting that body of research.

More than 50 groups have called for the US to follow the lead of dozens of other countries in banning paraquat. The Michael J. Fox Foundation for Parkinson’s Research submitted a petition to the EPA with 107,000 signatories calling for a ban. The foundation cited a study that found people exposed to paraquat in their teens or as young adults had an increased Parkinson’s risk of 200 to 600 percent, depending on the overall exposure.

A human toll- paraquat users blame Syngenta for Parkinson’s disease

By Carey Gillam and Aliya Uteuova

When Illinois farmer Ron Niebruegge was diagnosed with Parkinson’s disease at the age of 55, he was certain it must be a mistake. Niebruegge had always been healthy and active, someone who loved horseback riding and taking his wife dancing on weekend nights.

But a dizzy spell and a fall in 2007 led him to visit a neurologist, and then another. Both doctors agreed that the little things Niebruegge had started to notice – a left arm that didn’t seem to work quite right, some stiffness in his joints – were undeniable signs of the onset of Parkinson’s, a progressive debilitating brain disease for which there is no cure.

Now 70 years old, Niebruegge lives a very different life: The horses he loved have been given away and the horse trailer sold. Dancing is a thing of the past; Niebruegge struggles simply to walk across a room. He uses a cane but falls so frequently and unexpectedly that he fears leaving home.

One recent fall left him with a dislocated shoulder that required surgery. And his wife of 49 years has transitioned from dance partner to caregiver.

Niebruegge is far from alone. More than 8 million people globally suffer from what scientists see as the fastest growing neurological disorder in the world. And while scientists see multiple toxins as potential causes, one pesticide popular with farmers across the US has been prominently linked to the disease: a weed killer called paraquat that has grown in use over recent decades.

The longtime manufacturer of paraquat, Syngenta AG, along with Chevron USA, the successor to a former US paraquat distributor, are now being sued by thousands of Parkinson’s sufferers. The plaintiffs claim scientific studies show that exposure to paraquat can cause, or significantly increase the risk of, Parkinson’s disease, but rather than warn users, the companies prioritized paraquat sales over human health.
