Monsanto's Roundup Destroys Healthy Microbes in Humans and in Soils
By Julie Wilson
We're only beginning to learn the importance of healthy gut bacteria to our overall health—and the relationship between healthy soil and the human microbiome.
We know that the human microbiome, often referred to as our "second brain," plays a key role in our health, from helping us digest the food we eat, to boosting our brain function and regulating our immune systems.
Similar to animals, plants and soil, our bodies contain trillions of microbes—microscopic living organisms, such as bacteria, fungi and protozoa. The microbes in each person's body are unique, but not random. They colonize in the body, beginning from birth, depending on the microbes passed on by the mother. Over our lifetimes, they evolve according to our unique exposure to the outside world in order to protect us from disease such as cancer, diabetes and even autism.
What happens when our microbial community is disturbed? New research suggests that exposure to environmental toxins, such as pesticides, may alter the human microbiome, leaving us more vulnerable to sickness and disease.
A second new study suggests that the most widely used herbicide on the planet—Monsanto's Roundup weedkiller—could be causing more damage to our gut microbiome and overall health than we thought. Not only does the weedkiller contain glyphosate, but in its complete formulation, it also contains toxic levels of heavy metals, including arsenic.
Glyphosate and Its Unintended Effects
The study, published by Prof. Gilles-Eric Séralini at the University of Caen, France, raises new alarms about glyphosate, the most widely used herbicide in the world despite mountains of research pointing to the weedkiller's damaging impacts on human and environmental health.
Glyphosate, the key active ingredient in Roundup, is destructive to the environment. A recent article by GM Watch details the editor of No-Till Farmer, a magazine that advocates for the use GM crops and glyphosate herbicides in no-till systems, is changing his thinking.
John Dobberstein, No-Till Farmer's senior editor, recently wrote that "there may be trouble on the horizon for glyphosate," citing research showing that glyphosate lingers in the soil—and in high amounts—long after it has been applied.
Citing other researches, including Robert Kremer, a retired research microbiologist with the USDA-Agricultural Research Service and adjunct professor at the University of Missouri, Dobberstein wrote that glyphosate quietly lingers in soil years after it's been sprayed, damaging non-target crops and suppressing beneficial mycorrhizal fungi, which help plants obtain nutrients from the soil while offering protection against disease.
The herbicide also harms beneficial soil organisms such as small insects and earthworms, while leaving behind chemical residues that wind up in our waterways, Dobberstein wrote, as reported by GM Watch.
Microbes Prove Their Value in Humans
While some microbes cause disease, the majority of these cells assist us with everyday processes, such as digesting food and keeping harmful bacteria at bay.
According to an article published this month by Mercola.com, 70 to 80 percent of your immune function resides within your gastrointestinal tract or "gut." Poor gut health is associated with autism, behavioral disorders, diabetes, gene expression and obesity.
If, as this recent article in the Atlantic claims, "The microbial community in the ground is as important as the one in our guts," then the new Séralini study doesn't bode well for us humans—especially if we keep dousing the world's soils with glyphosate, and consuming glyphosate-contaminated foods.
Arsenic and Old Monsanto
As if there aren't enough reasons to be worried about glyphosate, one more reason emerged last week when scientists reported that glyphosate-based herbicides, including Roundup, contain toxic levels of heavy metals, including arsenic.
Glyphosate, the active ingredient in Roundup has been the subject of intense scrutiny and controversy. Documents recently made public as a result of multiple lawsuits filed against Monsanto by people who blame exposure to Roundup for their non-Hodgkin lymphoma suggest Monsanto has known for decades about the health risks related to glyphosate.
Some countries have banned its use.
But as the authors of this latest study point out, glyphosate is not the only ingredient in herbicides like Roundup—it's one of multiple ingredients. Those other ingredients make glyphosate-based herbicides even more dangerous than we thought—and should lead to a global ban on all glyphosate-based herbicides.
According to Prof. Gilles-Eric Séralini, one of the authors of the study:
These results show that the declarations of glyphosate as the active principle for toxicity are scientifically wrong, and that the toxicity assessment is also erroneous: glyphosate is tested alone for long-term health effects at regulatory level but the formulants—which are composed of toxic petroleum residues and arsenic—are not tested over the long term. We call for the immediate transparent and public release of the formulations and above all of any health tests conducted on them. The acceptable levels of glyphosate residues in food and drinks should be divided immediately by a factor of at least 1,000 because of these hidden poisons. Glyphosate-based herbicides should be banned.
We can only hope.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
