Glyphosate is back in the headlines…again. This time, it is resurfacing amid political crosscurrents, with figures inside the MAHA movement shifting tone and reigniting debate over what to fear in our food system. Lawsuits are recycled. Old studies are recirculated. Social media frames it as a clear villain hiding in plain sight. But as the volume rises, a harder question lingers beneath it: are we aiming our fear in the right direction? What actually happens inside the body when we’re exposed to glyphosate at the regulated levels found in food?
Unlike pesticides, which are intensely studied, regulated, and measured down to microscopic thresholds, microplastics exist inside a system we rarely question because it delivers what we value most: convenience. Lightweight packaging. Shelf stability. Portability. All at an affordable price. So the real question may not be whether concern is warranted. It is whether our concern is proportionate and whether convenience is quietly shaping which risks we amplify and which we tolerate.
What is Glyphosate? And Why Does It Exist?
Glyphosate, also known as RoundUp, is a broad-spectrum herbicide. It works by inhibiting an enzyme pathway critical to plants and certain microbes, a pathway humans do not have.
That biological distinction is part of why regulators historically viewed glyphosate differently than older classes of pesticides. It is used to control weeds in crops like corn, soybeans, wheat, and cotton. In many systems, it allows farmers to reduce tillage, which means fewer tractor passes, less soil disruption, and lower erosion. Modern no-till farming systems expanded in part because effective herbicides made weed control possible without repeatedly turning over the soil.
That’s not a minor detail. Soil erosion strips nutrients, releases stored carbon, and reduces long-term productivity. Weed pressure also reduces crop yields dramatically by competing for light, water, and nutrients. In unmanaged systems, yield losses from weeds can reach 30–50%, and in some regions, far higher. Before modern weed control, farmers relied on intensive cultivation, manual labor, and rotational timing to suppress weeds. That approach limited yield stability and required more land to produce the same food.
Today, herbicides like glyphosate are land-use efficiency tools. They are part of the infrastructure that allows eight billion people to eat from a finite acreage. From a toxicological standpoint, glyphosate also stands out: its acute oral lethal dose in rats is approximately 5,000 mg/kg, placing it in one of the lowest toxicity categories for herbicides. By comparison, common pesticide alternatives such as 2,4-D (~700 mg/kg) and dicamba (~1,700 mg/kg) are significantly more acutely toxic, and even some organic-approved herbicides like copper sulfate (~300 mg/kg) are far more toxic on the same scale.
The Cancer Question and What Regulators Actually Say
Few topics in modern food and agriculture generate as much confusion, and concern, as the question of whether glyphosate causes cancer. At the center of this debate are two very different scientific conclusions, often presented without the context needed to understand why they differ.
In 2015, the International Agency for Research on Cancer classified glyphosate as “probably carcinogenic to humans.”
This designation was based on hazard identification, meaning the agency asked whether glyphosate could cause cancer under certain conditions—not whether it does so at levels people are typically exposed to in everyday life. IARC’s classification places glyphosate in the same category as substances like red meat and working night shifts, which may come as a surprise to many readers.
In contrast, regulatory bodies tasked with assessing real-world risk have reached different conclusions. The U.S. Environmental Protection Agency, after reviewing decades of toxicological data and large-scale epidemiological studies, has concluded that glyphosate is “not likely to be carcinogenic to humans” at doses relevant to human exposure. Similarly, agencies in Europe, Canada, and Australia have arrived at comparable determinations, emphasizing that dose and exposure context matter when evaluating risk.
Much of the divergence comes down to methodology.
IARC evaluates whether a substance has the potential to cause harm under any circumstance, while regulatory agencies evaluate whether that harm is likely to occur under actual conditions of use.
These are not contradictory approaches, but they answer fundamentally different questions.
Adding further nuance, large prospective cohort studies, including research following agricultural workers with relatively higher exposure levels, have not found a consistent association between glyphosate use and cancer incidence. While no single study is definitive, the weight of evidence continues to shape how regulators assess safety thresholds and acceptable exposure limits.
For consumers, this creates a challenging landscape: one where a single headline, “probably carcinogenic,” can overshadow the broader scientific consensus on real-world risk. Understanding the distinction between hazard and exposure is essential. It does not mean glyphosate is beyond scrutiny, but it does mean that how, and how much, we are exposed plays a critical role in determining actual health outcomes.
What Happens Inside the Body
One of the most persistent fears surrounding pesticides is that they “build up” over time, with small daily exposures stacking silently in tissues until they reach a tipping point. That mental model makes intuitive sense. It just doesn’t match how glyphosate behaves in humans. Controlled biomonitoring studies measuring urinary excretion show that glyphosate is absorbed and then largely eliminated within hours. Estimates of its elimination half-life in humans are generally in the range of approximately 5 to 10 hours.
Most detectable glyphosate is cleared within a day or two after exposure. It does not bioaccumulate in fat tissue. It does not linger for months or years. This is not a “forever chemical.” That doesn’t mean exposure is irrelevant. Occupational handlers, applicators, and those in high-contact environments deserve rigorous safety oversight such as protective clothing. But for typical dietary exposure, the body treats glyphosate as something to process and remove, not something to store. The image of trace residues stacking indefinitely inside organs is not supported by any evidence. And this matters, because the persistence of a compound in the body is often more relevant to long-term risk than its mere detectability.
The Food System Without It
It is worth pausing to imagine modern agriculture without synthetic herbicides, not as a thought experiment, but as an economic shockwave.
Weed pressure would surge immediately. Farmers would be forced back to intensive mechanical tillage, increasing soil erosion, fuel use, labor costs, and carbon release. Yields in major commodity crops could fall sharply in many regions. That is not a cosmetic shift — that is a supply contraction. And when supply contracts, prices climb. Food inflation would not be marginal; it would ripple through grain markets, livestock feed, exports, and ultimately grocery shelves. More land would need to be brought into production, pushing into marginal acres and environmentally sensitive areas just to maintain baseline output.

This would not simply mean fewer perfect apples. It would mean tighter global grain stocks, higher input costs, and volatility in export markets that many developing nations rely on for staple foods. A 10–20% yield decline in crops like corn, soy, or wheat is not theoretical — it translates into billions of bushels lost. Agricultural productivity underpins food affordability, trade balances, and political stability. History shows that food price spikes destabilize governments far faster than most policy debates.
Pesticides are not flawless tools. But they are foundational ones. Removing them without scalable, economically viable alternatives would not usher in a pastoral renaissance of backyard abundance. It would mean lower yields, higher prices, greater land use, and amplified inequality in food access. Modern food security, imperfect as it is, rests on crop protection. That is not ideology. It is structural reality.
Meanwhile, Something Else Is Showing Up
While glyphosate dominates cultural attention, a different exposure has quietly moved from environmental issue to human issue.
Microplastics, plastic fragments smaller than 5 millimeters, and even smaller nanoplastics are now being detected in our organs.
Microplastics have been shown to cause inflammation, oxidative stress, tissue damage and further increase chronic diseases. In 2024, a study published in The New England Journal of Medicine reported microplastics and nano plastics embedded within carotid artery plaque. Individuals with detectable plastics in their plaque were significantly more likely to experience heart attack, stroke, or death over the following three years compared to those without detectable particles.
Other research has identified microplastics in lung tissue, placenta, blood, and even brain samples. Experimental work suggests potential mechanisms, including inflammation, oxidative stress, and cellular disruption. Plastic particles have even shown to change your DNA and prevent basic functions such as DNA repair systems.
Unlike glyphosate, microplastics are not a single molecule. They are particles. Their size, shape, polymer type, and chemical additives vary widely. Some may pass through the digestive tract. Others, particularly smaller particles, may cross biological barriers. There is no single established human “half-life” for microplastics. Because we do not yet fully understand how long they remain, or what their long-term biological consequences may be. And that uncertainty deserves attention.
The study did not prove causation. But it did something important: it demonstrated presence and association.
The Psychology of Fear
So why does one exposure dominate public panic while the other moves quietly through emerging literature?
Convenience.
Plastic makes life easy. It keeps strawberries from bruising in transport. It makes takeout possible. Milk in glass bottles has gone the way of the local dairy man. It reduces food waste by extending shelf life. It allows sterile medical packaging. It makes bottled water portable. It makes lightweight clothing affordable. Plastic underpins modern logistics.
To meaningfully reduce microplastic exposure would require enormous behavioral shifts. Using glass instead of plastic for heating food. Reducing single-use packaging. Filtering water. Rethinking synthetic textiles. That’s inconvenient. Pesticides, by contrast, feel distant and industrial.
Pesticides belong to “big agriculture.” They have brand names and lawsuits. They are easy to externalize, something done by someone else. Microplastics are personal. They come from the packaging in our fridge, the bottle in our car, the fibers from our clothes. We accept what makes our lives easier. We criticize what feels industrial and abstract. But the body does not respond to narratives. It responds to chemistry and particles.
The Real Risk Conversation
None of this means pesticides deserve a free pass. Continued research, transparent regulatory review, and improved agricultural practices are essential. Safer formulations and precision application matter. So does innovation.
It also does not mean microplastics are definitively causing disease at scale. It does mean our risk conversation should evolve.
We should ask:
- Which exposures bioaccumulate?
- Which persist in tissues?
- Which are present at biologically meaningful concentrations?
- Which trade-offs are structural to feeding the world, and which are conveniences we could redesign?
The modern food system is not simple. It is a balancing act between yield, sustainability, affordability, and safety.
Pesticides are tools that emerged to solve biological competition in crops. Plastics emerged to solve durability and transport problems in consumer goods. Both carry trade-offs.
But when it comes to biological persistence, they are not equivalent.
It’s also worth saying clearly: concern about pesticides and concern about microplastics are not mutually exclusive. We can, and should, scrutinize agricultural chemicals while also demanding better research and policy around plastic exposure. The point is not to minimize one risk in favor of another. It’s to think carefully about persistence, exposure levels, biological plausibility, and long-term effects, and to let science, not volume, guide our priorities.
Microplastics, meanwhile, have been found inside human arteries and organs. Early evidence links their presence to inflammatory pathways and cardiovascular outcomes. Their long-term biological behavior remains uncertain, and that uncertainty deserves careful study. One system underpins global food security. The other underpins global convenience. Finally, there is no simple solution to detox a human body from microplastics.
We should examine both.

We’re still without our long-overdue
























The continuation of the Black Sea Grain Initiative that opened the door for resumed exports also must be renewed this spring.
China’s top diplomat paid Putin a visit in February which sent nervous energy throughout the western world. National leaders worry that support from China and more aggressive action by Russia could expand the conflict still further, prompting more and more retaliatory response from the West.
So why are so many people still holding their breath about the ongoing conflict, and its potential threat to food security? The answer is simple.
News of the courage and resiliency of the Ukraine producer and the entire national agricultural sector has been inspirational.

In response to the dire situation, national leaders responded by negotiating the Black Sea Grain Initiative, which allowed a resumption of shipments under controlled conditions.
Prior to the recent Ukraine announcement, data from the United Nations already had shown the progress being made. UN estimated that more than 10.4 million tons of grains and other foods have shipped from Ukraine ports since the Initiative was signed in July.


The Nature Conservancy is pleased to present its Global Regenerative Food Systems Director, 
Supporting producers to mulch-till the residue instead of burning helps to clear the air and keeps people healthy. This also constitutes a regenerative ag practice which, in turn, will improve soil health, nutrient content and water management — all which lead to better outcomes for people and nature.

We’re committed to a system based on comparative advantage, in which all nations seek to exploit their natural advantages to supply the world with the commodities and food products they produce most efficiently.








To begin, Ukraine offers an abundance of natural resources, including agricultural products such as corn and oilseeds, minerals and other staples of living. Its central location between European and Asian markets makes it a natural source of supply in both directions. Its river system and access to warm-water ports promise steady and reliable delivery.




Drought affects both crop and livestock production, obviously. Dealing with the problem poses different sets of problems and issues for both.


We elected to continue that work by seeking current price information for the same 15-item food basket, but with data from the Northeast, mid-Atlantic, deep South, upper Midwest, Gulf Coast, Mountain region, and West Coast.










In Africa, where nutrition and food scarcity are real issues, studies have been done but the correlation is not always strong. The chart below shows the inconsistencies of zinc in the soil versus in the corn, cowpea, millet, and sorghum.
