How Poorer Countries Became the World’s Dumping Grounds

Monday, March 10, 2025

Picture a plastic shopping bag that some busy customer picks up in the checkout line of a store—say, the British supermarket Tesco. That shopper piles her groceries into the bag, takes it home to a flat in London, and then recycles it.Although she’ll think about the bag no further, its journey has just begun. From a recycling bin in London, it is trucked to Harwich, a port town 80 miles northeast, then shipped to Rotterdam, then driven across Germany into Poland, before finally coming to rest in a jumbled pile of trash outside an unmarked warehouse in southern Turkey. It might eventually get recycled, but it just as likely will sit there, baking in the sun, slowly disintegrating over years.For most plastic bags, this odyssey is invisible. To one particular Tesco bag, however, Bloomberg journalists attached a tiny digital tracker, revealing its months-long, transcontinental journey—“a messy reality,” the reporters wrote, “that looks less like a virtuous circle and more like passing the buck.”The story of this plastic bag appears early in Waste Wars: The Wild Afterlife of Your Trash, a new book by the journalist Alexander Clapp. The book reveals many such journeys, tracking the garbage of rich countries along hidden arteries toward some of the planet’s poorest places. One dark side of consumerism, it turns out, is all of the discarded wrappers and old iPhones piling up or being burned on the other side of the world.This dumping exacts a devastating environmental toll—leaching toxic contaminants into water, air, and food, and miring whole regions in growing fields of rubbish. It’s also reshaping economies, having birthed an informal disposal industry that now employs millions of people. Towns in Indonesia are buried in millions of pounds of single-use plastics; communities across India and Bangladesh are populated by armies of migrant laborers tasked with dismantling cruise liners and oil tankers by hand. To describe this dystopian reality, Clapp assembles a narrative that is part history, part sociology, part horrifying travelogue. The result is a colonoscopy in book form, an exploration of the guts of the modern world.The focus of Waste Wars may be trash, but the book highlights a literal manifestation of a much broader global dynamic: Rich countries tend to pass their problems on to poorer ones. Consider, for instance, the nuclear refuse that the United States dumped among Pacific island nations during the Cold War, which threatens radioactive disaster even decades later. Consider the refugees consigned by the United States to Latin America, by the European Union to Turkey and Pakistan, or by Australia to the island of Nauru. Consider, of course, the most devastating consequences of climate change, such as the rising seas threatening island nations that bear little responsibility for global carbon emissions.[Read: What America owes the planet]Waste Wars shows how wealthy, developed countries are, today, not only removing wealth from poorer, developing countries (in the form of materials and labor) but also sending back what the late sociologist R. Scott Frey called “anti-wealth.” In fact, the very places that long supplied rubber, cotton, metal, and other goods to imperial viceroys now serve as dumping grounds for the modern descendants of some of those same powers. This disheartening reality augurs a future in which the prosperity of a few affluent enclaves depends in part on the rest of the globe becoming ever more nasty, brutish, and hot.Toward the beginning of his book, Clapp describes a counterintuitive consequence of the landmark environmental laws passed in the United States in the 1970s. Statutes such as the Federal Environmental Pesticide Control Act of 1972 banned scores of toxic substances, while others, including the Resource Conservation and Recovery Act of 1976, made burying hazardous waste in U.S. soil much more expensive. A tricky new problem presented itself: what to do with all of the waste?“America’s newfound commitment to environmentalism came with a little secret,” Clapp writes. “It didn’t extend to other countries.” As similar laws were passed across Europe and North America, a thriving, semilegal international waste trade soon sprang up. Beginning in the 1970s and ’80s, wealthy nations exported such unloved materials as asbestos and DDT to impoverished nations like Benin and Haiti, which were desperate to develop their economies yet rarely possessed facilities capable of properly disposing of toxic materials. These countries faced a choice, Clapp writes: “poison or poverty.” By the end of the ’80s, more waste than development aid, dollar for dollar, was flowing from the global North to the global South.This dynamic was historically novel, yet it emerged from practices stretching back hundreds of years. In early modern Europe, the filthiest trades (such as tanning) were branded nuisances and forced out of cities and closer to those living at society’s margins. Factories, industrial smelters, and dumps were likewise relegated to places where Black and brown people in the Americas, or the Roma in Europe, or Dalits in India, were legally or economically compelled to live. As the historian Andrew Needham has noted, the 20th-century population boom of southwestern U.S. metropolises, including Phoenix, Albuquerque, and Los Angeles, relied on coal both mined and burned on Navajo and Hopi land—coal that by the early 1970s was generating five times more electricity than the Hoover Dam. The air-conditioned comfort of the Sun Belt, in other words, depended on the despoliation of Indigenous land.By the late ’80s, many developing nations had had enough. The leaders of Caribbean and African states united to draft the Basel Convention, a 1989 international agreement effectively outlawing the export of hazardous waste to other countries. Today, 191 nations have ratified the convention. (The United States is one of the only holdouts.) It’s a spectacular accomplishment—a testament to transnational organizing and solidarity—and also, as Waste Wars demonstrates, a hollow one.The global redistribution of “anti-wealth” did not cease; in fact, Clapp writes, it “exploded” in the 1990s. The rub lay in a provision of the Basel Convention, which stated that an object sent from one country to another for reuse, rather than disposal, wasn’t waste but a thing of value. Quickly, waste brokers learned to refer to their wares with such euphemisms as “recovered byproducts.” Those on the receiving end of the garbage learned to extract whatever value they could from discarded cardboard and busted laptops—and then dump, burn, or dissolve in acid what remained.To illustrate the profound consequences of the global recycling economy, Clapp traveled to the Ghanaian slum of Agbogbloshie, where (until it was demolished a few years ago) a shadow workforce of migrants lived at the foot of a five-story mound of discarded electronics. On paper, these items weren’t all waste—some of them technically still worked—but most were dying or dead, and the laborers of Agbogbloshie dutifully wielded hammers to strip old televisions and smartphones of precious metals and incinerate the rest. Clapp highlights the particular irony of Agbogbloshie—a slum “clouded with cancerous smoke, encircled by acres of poisonous dirt”—occurring in Ghana, the first sub-Saharan African country to free itself of colonialism. Despite the high hopes of its revolutionary generation, in some places, Ghana still experiences what Clapp calls “a story of foreign domination by other means.” More and more of these electronic-waste disposal sites are popping up around the world.Yet the biggest villain in the global trash economy is plastic, and Clapp shows in horrifying detail the intractability of this problem. Derived from fossil fuels, plastic is cheap, convenient—and eternal. When, in the late 1980s, the public started to get concerned about plastic detritus, the petrochemical industry began promoting “recycling.” It was, mostly, public relations; plastics are notoriously difficult to recycle, and it’s hard to make a profit while doing so. But the messaging was effective. Plastic production continued to accelerate.[Read: The cost of avoiding microplastics]In the mid-1990s, China emerged as the principal destination for used cups, straws, and the like; the country’s growing manufacturing sector was eager to make use of cheap, recycled raw plastic. As Clapp reports, over the following quarter century, China accepted half the globe’s plastic waste, conveniently disappearing it even as air pollution spiked in its destinations in the country’s southeast. The plastic waste China received was filthy, much of it too dirty to be cleaned, shredded, and turned into new plastic.The result was not only environmental catastrophe but license for unchecked consumption of cheap plastic goods that can take a few minutes to use but hundreds of years to decay. In the United States, plastic waste increased from 60 pounds per person in 1980 to 218 pounds per person in 2018. There is now a ton of discarded plastic for every human on the planet; the oceans contain 21,000 pieces of plastic for each person on Earth.In 2017, citing pollution concerns, China announced that it would no longer accept the world’s plastic waste. “There was an opportunity here,” Clapp writes, for the world to finally tackle the problem of unsustainable plastic production. Instead, governmental and industrial leaders chose a simpler solution: “redirecting the inevitable pollution blight from China to more desperate countries.” In just two years, the amount of American plastic waste exported to Central America doubled; worldwide exports to Africa quadrupled, and in Thailand they increased twentyfold.The international waste trade is a “crime,” Clapp concludes, and the refusal to address its root causes is a dereliction bearing “certain similarities to international failures to address the climate crisis.” Waste Wars demonstrates the mounting consequences of such inaction: Residents of wealthier nations are jeopardizing much of the planet in exchange for the freedom to ignore the consequences of their own convenience.

A new book shows how residents of wealthier nations are jeopardizing the health and safety of other parts of the planet.

Why Lung Cancer Is Increasing among Nonsmoking Women Under Age 65

Thoracic surgeon Jonathan Villena explains why early screening for lung cancer is critical—even for those without symptoms.

Rachel Feltman: For Scientific American’s Science Quickly, I’m Rachel Feltman.Lung cancer is the deadliest cancer among women in the United States, surpassing the mortality numbers of breast and ovarian cancer combined. And surprisingly, younger women who have never smoked are increasingly being diagnosed with the disease.Here to explain what could be driving this trend—and why early screening can make all the difference—is Johnathan Villena, a thoracic surgeon at NewYork-Presbyterian and Weill Cornell.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Thank you so much for joining us.Johnathan Villena: Thank you for having me.Feltman: So our viewers and listeners might be surprised to hear that lung cancer [deaths] in women now tops breast cancer, ovarian cancer combined. Can you tell us more about what’s going on there?Villena: Yeah, definitely. So in general lung cancer is the number-one cancer [killing]people in the U.S., both men and women. If you look at the American Cancer Society, around 226 new—226,000 new cases of lung cancer are projected to be diagnosed in 2025. Of those about 50 percent are cancer-related deaths, meaning [roughly] 120,000 people die every year from lung cancer. Now, what’s—the good news is that the incidence has actually been decreasing in the last few years.Feltman: Mm.Villena: If you look at the American Cancer Society’s statistics, in the last 10 years [ of data, which goes through 2021], the, the incidence of lung cancer has decreased in men around 3 percent per year. And it’s about half of that in women, meaning it’s decreasing [roughly] 1.5 percent per year. So one of the reasons that they think that this might be happening is that there was an uptick in smoking in women around the ’60s and ’70s, and that’s why we’re seeing a slight, you know, decrease in the incidence in men but not so much in the women.What’s more interesting and very surprising is the fact that when you look at younger people, meaning less than 65 years old—especially younger never-smoking people—there’s actually an increase of women in that subgroup. They’re overrepresented, and that’s something very surprising.Feltman: Does the research offer us any clues about what’s going on in this demographic of younger women?Villena: Yeah, so there’s been a lot of research. So, you know, in general—and something that people don’t know is that about 20 percent of lung cancers actually occur in people that have never smoked in their entire lives.Feltman: Mm.Villena: This is something that we don’t really understand why this happens to this one in five people, but there are some risk factors associated with it. Number one is exposure to radon, which is a natural gas that sometimes people are exposed to for a prolonged time. Number two is secondhand smoking ...Feltman: Mm.Villena: So they don’t smoke directly, but they live in a household where they smoke. And number three are kind of other environmental factors, things such as working in a specific, you know, manufacturing plant that deals with specific chemicals. And then lastly, the one that has had, actually, had a lot of research into it are genetic factors. There’s definitely a preponderance of certain mutations in somebody’s genes that can cause lung cancer, and that is overrepresented in women.Feltman: Do women face any unique challenges in getting diagnosed or treated when it comes to lung cancer?Villena: So, yes. First of all, you know, how do we treat or catch lung cancer? So the newest and, and latest way of catching this disease is actually through lung cancer screening.That’s something that’s relatively new; it’s only happened in the last 10 years. And that’s in certain demographics, meaning that if someone is over 50 years old and they have smoked more than one pack per day for 20 years, they meet the criteria for lung cancer screening, which is basically a radiograph or a CAT scan of their lungs. That’s the way that we pick up lung cancer.That’s the—almost the exact same thing that people have for breast cancer, such as mammography, or colonoscopy. So that’s before any symptoms come in. That’s really just to try to capture it when it’s in very nascent stages, right?Feltman: Mm-hmm.Villena: Where it’s very small or not symptomatic. And that’s the way we diagnose a, a lot of lung cancer.Now, that being said, there’s a couple of things. So first of all, [roughly] 60 to 70 percent of people, like, in general get mammographies.Feltman: Mm-hmm.Villena: [About] 60 to 70 percent of people get colonoscopies. Only 6 percent of people actually get lung cancer screening. So it’s dismally low.Feltman: Yeah.Villena: The reason being that sometimes people don’t know about it; it’s relatively new. Sometimes even doctors don’t know about it. There’s also a little bit of guilt involved, where people, you know, they think they did it to themselves by smoking ...Feltman: Hmm.Villena: So they don’t wanna go do it. The second thing is that, as you could imagine, this is only for high-risk individuals or people that have a history of smoking, all right? So it misses these never-smoking one in five patients. So that’s one of the things that we’re actively working on.Feltman: Yeah, how else does the, you know, the stigma associated with lung cancer because of its association with smoking, how does that impact people’s ability to get diagnosed and treated?Villena: I think there’s a lot of hesitancy between patients. There’s, you know, a recent study that showed that people are more—have more tendency to downplay their smoking history, meaning that if they quit, let’s say 10 years ago, you tell your doctor that you never smoked.Feltman: Mm.Villena: And that’s something very common. Or if you smoked, you know, one pack a day, maybe you say you smoked half a pack a day because you feel that guilt. So then you don’t give your doctor or your caretaker the full picture. And sometimes that prevents you from getting these tests, right? So there’s definitely that attitude.There’s also a bit of a fatalistic attitude, sort of like, “I did it to myself. I’d rather not know. You know, this is something that—you know, I made that choice, and if I get cancer, that’s my choice.” Right? So that’s, that’s also another attitude that we’re constantly trying to change in patients. You know, the treatment, once you capture it, is all the same, but really it’s about getting screening and it’s about finding the lung cancer.Feltman: So with smoking no longer necessarily being the driving factor, at least in this younger demographic, what kinds of risk factors should we be talking about more?Villena: So I think, you know—so smoking is always number one.Feltman: Sure.Villena: In the never-smoking people it’s either radon, secondhand smoking or environmental factors, and then a little bit of genetics plays, plays a part.Radon is something that people can test for in their homes. It’s something that people should read up on. So that’s number one: if you have exposure to that, to get rid of that.If you are in, in an environment, let’s say you work with chemicals that you think, you know, are astringent or have caused—causes you to have coughs or, you know, affects you in any sort of way, to kind of try to talk to your employer to work in a more ventilated setting.Really important with genetic factors is understanding your family history.Feltman: Mm.Villena: If you have a mother, a grandmother, a grandfather who died of cancer or you have a lot of cancer in your family, sometimes understanding that and knowing that from your, you know, from your family perspective will actually clue a doctor in to doing further tests, to looking into that further, ’cause that sometimes is passed down and you can have the same genes.Feltman: Are there any big research questions that scientists need to answer about lung cancer, specifically in young women?Villena: So, you know, there’s so much to look at, all right? So if we think about just the genetic aspect of it, there’s one specific gene called the EGFR gene—or it’s a mutation that’s found in lung cancer that in, if you look at all people with lung cancer, it’s found in about 15 percent ...Feltman: Mm-hmm.Villena: Of the population with lung cancer. Now, if you look at never-smoking Asian women that get lung cancer, it’s about 60 percent of them ...Feltman: Mm.Villena: Have that mutation. So the important thing about that EGFR mutation is there’s a specific drug for that mutation, all right?So there’s definitely a lot of genetic kind of information that we’re still actively researching. But the important thing about this genetic information is that there’s drugs targeted specifically for those mutations. So the more we know, the more we understand, the better.Feltman: So for folks who are hearing this and are surprised and, and maybe concerned what is your advice for how they should proceed, how they should look into their risk factors?Villena: You know, I think one of the, the, the major aspects of health in general is understanding your own health.Feltman: Mm.Villena: I think that younger people tend to delay care, tend to not see their doctors, and because, one, they’re busy, right, at their very busy moment in their lives. But second is that, you know, you don’t wanna deal with it, and you think that you will not get cancer, that you will not get this disease because you’re young and you’ve never smoked and you’ve never done anything bad.Feltman: Mm.Villena: But, you know, you have to be very aware of your body, so what are the kind of top four symptoms? So number one, let’s say you have a cough, and that cough lasts for longer than two weeks, right?Feltman: Mm-hmm.Villena: A normal cold, things like that will go away after a couple of weeks. But if it’s there for a couple of months, and I’ve definitely seen patients that tell me in retrospect, you know, “I’ve had this cough for three months,” right, and it should have been checked up sooner. So understanding yourself, understanding your body, not, you know, waiting for things, not procrastinating, which is very hard to do, but you should definitely see your doctor ...Feltman: Yeah.Villena: Regularly.Second is, like I said before, understanding your family, right, and what your genetic makeup is, right? Knowing your family history, understanding if your parents, grandparents had cancer, etcetera, or other chronic diseases.Feltman: Mm-hmm.Villena: And that’s, that’s basically the, the major aspects of it. It’s really being in tune with yourself.Feltman: So once a patient is actually diagnosed, what does treatment look like?Villena: So treatment for lung cancer, actually, is heavily dependent on the stage. There’s everything from stage 1, in which it’s localized to one portion of a lung, to stage 4, where it actually has gone to other parts of the body.Now, stage 1 disease, you basically need a simple surgery, where that lung nodule, or that lung cancer, is surgically removed, and typically you don’t need any other treatments. So stage 1 is what we look for. Stage 1 is the reason that lung cancer screening works because stage 1 doesn’t really have any symptoms ...Feltman: Mm.Villena: So when you find it that early patients do very well.Stage 4, once it’s left the lung, you are no longer a surgical candidate, unless in, you know, sometimes very specific cases, but for the most part you’re no longer a surgical candidate. And there you need systemic treatments.Feltman: And how long does the treatment tend to take for a stage 1 patient, if it’s just a surgical procedure?Villena: So if it’s just a surgical procedure, look, I do these surgeries all the time: the patient comes in; we do the surgery; the patients usually go home the next day.Feltman: Wow.Villena: And then we follow the patient and get CAT scans every six months for a long time to make sure nothing comes back or nothing new comes. So it’s pretty straightforward, and we do this all the time. We do these surgeries robotically now. Patients recover incredibly well, and they’re out, you know, doing—living their lives in a couple of weeks. So it’s really something very, very, very efficient.Feltman: Yeah, so huge incentive to get checked early.Villena: Mm-hmm.Feltman: Are there any advances in treatment, you know, any new treatments that doctors are excited about?Villena: Yeah, so there’s two major steps forward that have changed lung cancer treatment. Number one is something called targeted therapy.Feltman: Mm-hmm.Villena: So that means that there’s a drug that targets a specific mutation. So just how I was speaking about earlier about the EGFR mutation in young, never-smoking Asian women, there is a drug that targets that mutation that has really shown amazing results at all stages now.And the second one is actually immunotherapy, which won the Nobel Prize, which is this idea that you can use your own body’s immune system to kill the cancer cell. So cancer is very smart—what it does is it evades your immune system; it pretends that it’s part of your own body. And what this drug does is that it basically reawakens your immune system to recognize that cancer again and kill it. And we’ve seen amazing results, even in the stage 4 patients, where they are potentially cured of cancer, which, which we’ve never seen before.Feltman: What motivated you to get into this specialty?Villena: You know, I do have a family history of this in an uncle that passed away from lung cancer ...Feltman: Mm.Villena: And he was a heavy smoker. And, you know, I saw how, basically, decimated his, he was—[his] life [was], basically. He was a very vibrant guy, he was very active, and in six months he was gone, right?And I think, you know, once I started getting into, you know, medical school and understanding things, one of the major things that I really got into was research. And I see that if my uncle had been treated 20 years ago, he potentially could have been saved ...Feltman: Mm.Villena: Because of these advances in research. And right now we are right at the cusp where we are learning all these new things, and we actually have the tools to change how patients are treated, you know? And this—every year there’s a new treatment, which prior to that, there was no new treatment; i t was basically just chemo, and that’s it, all right? So I think that that really motivated me—something that I can actually take part in and actually change the course for a lot of people.Feltman: Well, thank you so much for coming on to chat with us today.

California Gov. Gavin Newsom (D) vetoed a bill that would have banned the use of “forever chemicals” in cookware and other products in California. The bill became a source of controversy in the Golden State, with celebrity chefs among those who rallied against the cookware ban, while environmental and health activists have argued for it. It would have blocked the sales of cleaning products, dental floss, children's products, food packaging and ski wax that contained such chemicals starting in 2028 and cookware with them starting in 2030. While the bans would have only applied in California, the state’s sheer size gives it significant influence over what gets manufactured for sale across the nation. Newsom, in his veto message Monday, raised concerns about the availability of affordable cookware if the ban were to be implemented. “The broad range of products that would be impacted by this bill would result in a sizable and rapid shift in cooking products available to Californians,” the likely 2028 presidential hopeful wrote. “I appreciate efforts to protect the health and safety of consumers, and while this bill is well-intentioned, I am deeply concerned about the impact this bill would have on the availability of affordable options,” he added. However, proponents of the bill say the veto will result in more exposure to toxic chemicals.  “By vetoing SB 682, Governor Newsom failed to protect Californians and our drinking water from toxic forever chemicals,” said Anna Reade, director of PFAS advocacy with the Natural Resources Defense Council, in a written statement.  “It’s unfortunate that misinformation and greed by some in the cookware industry tanked this policy,”  Reade added. Forever chemicals are the nickname of a group of chemicals called PFAS that have been used in a wide variety of everyday products, including those that are nonstick or waterproof. Exposure to them has been linked to prostate, kidney and testicular cancer, as well as immune system and fertility issues.  They can persist for decades in the environment instead of breaking down and have become pervasive in U.S. waterways, tap water and human beings. California has historically been a relatively aggressive state in terms of environmental and product regulations — for example, requiring that products containing certain chemicals contain warning labels. However, several other states have already banned PFAS in cookware and other products.

Costa Rica is one of the countries that uses the most agrochemicals, which has a series of negative repercussions in various areas. A recent study revealed that the intensive use of agrochemicals in the horticultural region of Zarcero causes physiological stress in earthworms, leading them to flee from contaminated soils. This demonstrates the vulnerability of these organisms to environmental alterations caused by such substances. The research was carried out by student Gabriel Brenes from the Regional Institute for Studies on Toxic Substances at the National University (Iret-UNA) as part of the requirements for a Master’s Degree in Tropical Ecotoxicology. Through both field and laboratory studies on earthworm species abundant in the area, the research determined a reduction in enzyme activity and defense mechanisms when the worms were exposed to soils containing agrochemicals or samples taken from them. After conducting behavioral tests, it was found that 90% of the worms avoided remaining in contaminated environments, moving instead to soils managed with organic practices or with lower agrochemical use. According to the study, this could have consequences for agricultural activity, as earthworms improve soil fertility, facilitate nutrient cycling and water movement, and contribute to the decomposition of organic matter. “The intensive use of agrochemicals induces physiological stress in earthworms and causes them to flee contaminated soils. This can have repercussions on the microfauna community and the ecosystem services that sustain agriculture,” explained Brenes. Evidence of reduced intestinal microbial diversity in soil worms exposed to agrochemicals indicates alterations that negatively affect soil health. “We found that the intestinal microbiome of earthworms functions as a sensitive bioindicator of soil health. A reduction in its diversity can affect not only the organisms themselves but also the ecological services they provide, such as fertility and nutrient recycling,” said the researcher. It also detected seasonal changes in microbial composition between the dry and rainy seasons on organic farms with good practices, demonstrating plasticity and adaptation to environmental conditions. For example, during the rainy season, there was an increase in the abundance of genera such as Lactobacillus and Acinetobacter, which were not dominant in the dry season. In contrast, worms from conventional soils showed no seasonal change in their intestinal communities, indicating a loss of ecological flexibility. The research showed that contamination is not limited to plots where agrochemicals are applied. Residues reach organic farms and nearby forest areas, confirming processes of drift and environmental transport. In Zarcero, a small area with intensive horticultural production, the presence of agrochemicals in untreated soils demonstrates that environmental exposure is widespread. The excessive use of agrochemicals in our country is aggravated by the fact that 93% of them are classified as highly hazardous.

More And More People Suffer From 'Chemophobia' — And MAHA Is Partly To Blame

The fear tactic strikes a nerve with both conservatives and liberals alike. Here’s what you need to know.

If you’ve ever muttered to yourself, “I should really get the organic peaches,” or “I need to replace my old makeup with ‘clean’ beauty products” or “I really want to buy the “non-toxic’ laundry detergent,” you may have fallen into the chemophobia trap, an almost inescapable phobia that’s infiltrating lots of homes. Chemophobia is complicated, but, in short, it’s a distrust or fear of chemicals and appears in many of aspects of life from “chemical-free” soaps and “natural” deodorants to vaccine distrust and fear-mongering about seed oils.But, unlike most things, it plays on the emotions of both conservative MAGA voters and liberal MAGA opposers, even though actual chemophobia-based thoughts vary significantly in each group.“Much of this started on the left-leaning side of the political aisle as a result of misunderstanding the difference between legitimate chemical industrial incidents and just chemicals more broadly,” said Andrea Love, an immunologist, microbiologist and founder of Immunologic, a health and science communication organization.Appealing to the left, it was seen as counter-culture and opposed the “evil market forces,” said Timothy Caulfield, the co-founder of ScienceUpFirst, an organization that combats misinformation, and author of “The Certainty Illusion.”“But now we’re seeing it shift to the right, and I think it’s almost now entirely on the right, or at least the loudest voices ... are on the right,” Caulfield noted. These are voices like Casey Means, a wellness influencer and surgeon general nominee, and even Robert F. Kennedy, Jr., the Health and Human Services secretary.On the right-leaning side, chemophobia appears as a distrust and demonization of things like studied vaccines and medications and the pushing of “natural” interventions, “when those have no regulatory oversight compared to regulated medicines,” Love noted.“On the left-leaning [side], this gets a lot of attention because it plays into this fear of toxic exposures, and this ‘organic purity’ narrative ... ‘you have to eat organic food, and you can’t have GMOs,’” Love said.No matter your political party, chemophobia has infiltrated people’s homes, diets and minds, while also infiltrating brand slogans, marketing campaigns and political messaging (ahem, Make America Healthy Again). Here’s what to know:Chemophobia says you should avoid chemicals, but that’s impossible — water is a chemical and you are made up of chemicals.“First of all, everything is chemicals,” said Love. “Your body is a sack of chemicals. You would not exist if it were not for all these different chemical compounds.”Chemophobia leads people to believe that synthetic, lab-made substances are inherently bad while “natural substances” — things found in nature — are inherently good, and that is just not true, Love said.The current obsession with “all-natural” beef tallow as a replacement for “manufactured” seed oils is a prime example of this.“Your body ... has no idea if it’s a synthetic chemical, meaning it was synthesized in a lab using chemical reactions, or if it exists somewhere out on the planet,” Love added.Your body doesn’t know the difference between getting vitamin C from a lime and getting vitamin C that’s made in a lab, she explained. Your body only cares about the chemical structure (which is the same in synthetic chemicals and natural chemicals) and the dosage you’re being exposed to, Love noted. “This irrational fear of chemicals, just by and large, is antithetical to life because chemistry and chemicals are why everything exists,” Love said.Everything that is made up of matter is a network of chemicals, she explained. That goes for your body, your pets, your car, your TV, your home and the food you eat.“Everything is just these structures of chemicals linked together into physical objects ... so, there’s zero reason to be afraid of chemicals broadly,” said Love.Chemophobia was born from the ‘appeal to nature fallacy’ and a desire to ‘get back to ancestral living.’Chemophobia was born from the “appeal to nature fallacy,” said Love, which is “the false belief that natural substances ... are inherently safe, beneficial or superior, whereas synthetic substances are inherently bad, dangerous, harmful or worse than a natural counterpart.” There is nothing legitimate about this belief, she added. But both chemophobia and the appeal to nature fallacy are central to pseudoscience, the anti-vaccine movement and the MAHA wellness industry, Love noted.At the core of chemophobia and appeal to nature fallacy is also a “romanticization of ancestral living, when, in reality, we lived very poorly, we died very young and often suffering and in pain,” Love said.“Going back to simpler times” are talking points for both MAHA and MAGA, which, of course, stands for “Make America Great Again,” a slogan that alludes to the past. And, RFK Jr. has repeatedly claimed America was healthier when his uncle, John F. Kennedy, was president.This is complicated, but not true; two out of three adults died of chronic disease and life expectancy was almost 10 years less than it is now, according to NPR.Chemophobia is designed to elicit negative emotions such as anxiety and fear.Chemophobia is incredibly effective because it evokes people’s negative emotions, said Love. And it’s hard for most people to separate emotions from facts.If someone on social media says that a certain ingredient is harming your kids, you’ll be scared and want to make lifestyle changes. If someone claims your makeup is bad for you, you’ll also be scared and want to make changes.“Take, for example, fructose, since it’s having a moment,” said Andrea Hardy, a dietitian and owner of Ignite Nutrition, who is referring to a viral social media video about the “harms” of fructose.“An influencer online might say ‘fructose is bad, the liver can’t handle it, we shouldn’t be eating any fructose. I’ve cut all fructose from my diet and I’m the healthiest I’ve ever been.’ Then a mom, wanting to do the best for her children says, ‘I need to cut out all fructose’ and not only removes the ultra-processed foods like sweetened beverages, but also says no to fruit in her household because of this misinformation,” Hardy said.This has lots of consequences, including a lack of nutrition in the home (from missing out on the fiber and vitamins from fruit) and the encouragement of disordered eating in kids, who, from this elimination of fructose, will learn the false idea that “fruit is bad” or “fructose is bad,” explained Hardy.Illustration: HuffPost; Photos: GettyChemophobia makes products that claim to be "natural" or "clean" feel superior, even when that isn't the case.Our brains want clear, black-and-white information. Vilifying one product while celebrating another achieves that.Between social media and the internet, we live in a “chaotic information environment,” according to Caulfield. There’s seemingly factual information coming at you from everywhere, and it can be hard to know what to trust.“The reality is, our brains want simple. They want black and white,” said Hardy. We make choices all day long, which makes categorizing things, like food, as “good or bad” appealing to our minds, Hardy said.And, everyone wants to make the “good” choice, Caulfield added. “We want to do what’s best for ourselves and for the environment and for our community and our family,” he said.As a result, we look for “clear signals of goodness,” or “short cuts to making the right decision,” added Caulfield. We turn not only to words like “good” or “bad,” but also “toxin-free,” “natural” and “clean,” he said.Seeing these words slapped on a jar of nut butter, on a shampoo bottle, or on sunscreen makes making the “right choice” easier, he added — “even though the evidence does not support what’s implied by those words, those ‘health halos,’” noted Caulfield.These words are an “oversimplification,” Hardy said. “People now leverage their social media presence to share those oversimplified nutrition messages, most of which are at best, wrong, at worst, harmful.”Chemophobia is really hard to escape. It’s even built into marketing campaigns and product names.If you’ve ever fallen into the chemophobia trap without knowing, you aren’t alone. It’s complicated and nuanced, and the science is, at times, messy.Moreover, chemophobia is the inspiration behind brand names and entire product categorizations; “clean beauty” is one huge example.Fears of chemicals are now marketing ploys. “You’re going to find products that claim that they’re ‘chemical-free,’ and that doesn’t exist,” Love said, referring to the fact that, once again, everything is made up of chemicals.Market forces take over and cling to the chemophobia buzz words of the moment, whether that’s “clean” “gluten-free” or “non-GMO,” Caulfield said.Now, we have Triscuits labeled with non-GMO marketing, he said. We also have entire product lines at stores like Sephora that are categorized as “clean.”“It creates this perception [of] ‘if that one’s chemical-free, then the alternative that isn’t labeled as such must be dangerous, must be bad,’” Love said.Once again, making the “good” choice easy.This isn’t to say there isn’t room for improvement in the health and food space.“I work in the public health space. I don’t know a single public health researcher, a single agricultural researcher, a single biomedical researcher who doesn’t want to make our food environment safer for everyone,” said Caulfield.Just because Caulfield speaks out against chemophobia doesn’t mean he doesn’t want to make our food and health environment healthier, he stressed.“I do think we should always be challenging both industry and government to do exactly that, but at the same time, we have to be realistic and understand the nature of the risks and the magnitude of risks at play,” he said.Both our food environment and agricultural practices could be safer, “but those moves should be based on what the science says, and not on slogans,” Caulfield said.Corporate greed and capitalism hinder these safety changes.“The huge irony here ... the answer to all of these chemophobia concerns ... it’s more government regulation. It’s more robust, science-informed regulation. And in this political environment, that ain’t going to happen, That just simply isn’t going to happen, as we’ve already seen,” Caulfield said.The Trump administration wants to repeal environmental protections that help fight climate change (and the air we breathe has huge health implications) and has cut funding to departments that are in charge of food safety, which could jeopardize the items you buy at the grocery store.“So, it all just becomes slogans and wellness nonsense,” along with the peddling of unregulated, unproven supplements (that are basically just untested chemicals), Caulfield added.And, many of the people who claim to be so concerned about chemicals then profit from the sale of unregulated supplements, Caulfield said.Jeff Greenberg via Getty ImagesThe hyper-focus on things like food dyes and seed oils actually distracts from the true health — and healthy equity — issues in this country.Focusing on one ‘bad’ ingredient or so-called ‘natural’ alternatives won’t actually make you healthier.This fear of chemicals will have an enormous impact and is “something we won’t even realize and see the effects of for years to come,” Hardy said.“If we want to improve public health, focusing on a single ingredient in food or swapping seed oils for beef tallow isn’t the answer to our public health problems, it’s a distraction,” Hardy said.Food dyes, seed oils, “non-clean” beauty, whatever the item may be, become a common enemy, allowing folks to ignore the fact that this isn’t actually a problem that’s central to the country’s health outcomes, Love added.RFK Jr. has claimed that “Americans are getting sicker” and research does show that America has worse health outcomes while spending more on health care than other Western countries, but it’s too simple (and flat-out wrong) to blame any one makeup chemical or item in your pantry.“Instead of critically assessing and saying, ’Hey, we do have some health challenges, but what are the underlying factors to that? Maybe it’s housing inequity and lack of national health care and all of these societal, structural issues, and it’s not these singular food ingredients,” Love said.“These conversations distract us from the real things that we can do to make ourselves and our communities healthier, and I think that’s one of the biggest problems with MAHA,” said Caulfield.“No one’s a huge food dye fan. I’m not going to go to the mat for food dye [but] ... all these are distractions from the things that really matter to make us, to make our communities healthier — equity, justice, access to health care, education, gun laws — these are the things that, on a population level, are really going to make a difference,” Caulfield said.Whether someone has conservative or liberal views that fuel their chemophobia, the fear of chemicals is dangerous. And, it’s, sadly, more prevalent than ever, Caulfield said.It’s causing people to say no to necessary vaccines, not wear sunblock out of fears of “toxins,” avoid fruit because of fructose and more.YourSupportMakes The StoryYour SupportFuelsOur MissionYour SupportFuelsOur MissionJoin Those Who Make It PossibleHuffPost stands apart because we report for the people, not the powerful.
