New Study Shows Why Roundup Herbicide (Glyphosate) Should
Be Banned
A concerning new study published in Chemosphere shows that the classical toxicology model, based on the testing of individual molecules, is incapable of accurately estimating the global environmental and health risks of mixtures of agrochemicals like glyphosate (aka Roundup) and its degradation byproduct AMPA, which are now ubiquitous environmental and food contaminants and much more harmful than previously believed.
Following closely on the heels of a study showing that Roundup herbicide is 125 times more toxic than its active ingredient glyphosate studied in isolation, the new study adds to an increasingly damning body of evidence that reveals agrochemicals used in GMO food production are vastly more harmful than their manufacturers, regulators and proponents will admit.
The study, titled, "Genotoxicity of mixtures of glyphosate and atrazine and their environmental transformation products before and after photoactivation,"evaluated the light-induced cell-damaging toxicity (i.e. photo-inducible cytogenetic toxicity) of glyphosate, atrazine, aminomethyl phosphoric acid (AMPA), desethyl-atrazine (DEA), and their various mixtures.
Glyphosate (aka Roundup) is the world's most popular pesticide, used primarily in GMO farming as a systemic herbicide. When glyphosate is metabolized within plants or within the liver of animals, it produces AMPA, a substance that while classified as inert and/or harmless by regulators, has been known for some time to be at least as toxic as glyphosate, the latter of which has been linked to over 30 adverse health effects.[1] Atrazine is used to control weeds in crops such as corn and surgarcane, and is used widely in residential lawns and golf courses. It was identified as the most commonly detected pesticide contaminating drinking water in the United States,[2] and is believed to a potent endocrine disrupter affecting animal hormonal systems.[3]-[4]
Herbicide Mixtures And/Or Metabolites 20-1,000 Times More Toxic Than Regulators Believe
The new study demonstrated that the cell-damaging (cytogenetic) potentials of pesticides greatly depended on their physicochemical environment. Also, it was found that the mixture made with the four pesticides was not only 20-fold more toxic to tested cells than those of the most active compound AMPA, but that the toxicity increased 100-fold after light-irradiation, which would be a common reaction given that these chemicals persist and accumulate in the environment.
Additionally, researchers discovered that, "AMPA displayed a direct cytogenetic toxicity which was 1000 fold higher than that of its parent compound [glyphosate]." Since AMPA – the breakdown product of glyphosate -- is a ubiquitous toxicant, found in all glyphosate exposed plant food, and is known to persist for prolonged durations in the environment (76–240 days in soil), and is even produced in the mammalian liver following consumption of glyphosate contaminated food, the significance of this finding can not be underestimated.
When you consider that glyphosate is presently allowed in human food at levels up to six orders of magnitude higher than research has revealed may be harmful to the human body,[5] AMPA's potential for being 1,000 times more toxic than glyphosate implies that present day 'acceptable levels' may be up to 9 orders of magnitude -- 1,000,000,000 times -- too lax than required to protect exposed populations from significant bodily harm.
Given the growing body of evidence suggesting that glyphosate and its metabolite, AMPA, are extremely toxic, the precautionary principle should be implemented and unnecessary exposure should be avoided. If Roundup herbicide use is not restricted or banned until undergoing review, at the very least, consumers deserve the right of informed consent.
The choice to avoid non-GMO and non-Roundup laden foods must be made available through truthful labeling of food products. Failing to make this choice possible, or worse, levying massive financial and political resources against such a right through industry front groups like the Grocery Manufacturers Association, amounts to forced chemical poisoning, an egregious crime against humanity.

Renowned NYU Professor: GMOs Could Literally Destroy the Planet
What effects will
the genetic manipulation of nature have on our worldwide ecosystem? Photo

Nassim Taleb, a renowned New York University (NYU) professor recently raised eyebrows when he said genetically modified organisms (GMOs) have the potential to cause “an irreversible termination of life at some scale, which could be the planet.”
Taleb, who specializes in risk engineering, has outlined the dangers of GMOs in The Precautionary Principle, a paper recently made available to the public.
The threat
Often, GMO seeds are favored because of their ability to yield larger harvests and avoid certain pests or weeds that usually eat up some of their productivity, reports Daily Finance.
Taleb’s primary concern isn’t that ingesting GMOs is necessarily bad for people; rather, he’s focused on what effects the genetic manipulation of nature will have on the worldwide ecosystem. While Taleb concurs the risk of any one GMO seed ruining the planet is incredibly small, he argues that people are underestimating the domino effect of risk that’s involved.
For example, if one genetically modified seed produced holds a 0.1 percent chance of causing a catastrophic breakdown of the ecosystem, then the probability of such an event will only increase with each new seed that’s developed.
Taleb writes that given enough time the “total ecocide barrier” is bound to be hit despite incredibly small odds.
The argument hinges on the fact that GMOs represent a systemic, and not localized, risk. As GMO goods continue to be exported to countries throughout the world, the idea of being able to control GMOs in nature is impossible to guarantee.
As Taleb says, “There are mathematical limitations to predictability in a complex system, ‘in the wild,’ which is why focusing on the difference between local (or isolated) and systemic threats is a central aspect of our warnings.”
Responding to
critics
GMO supporters have criticized his work as GMOs have yet to significantly harm the ecosystem, but Taleb argues that point strengthens his theory.
Daily Finance reports:
The Precautionary Principle—which is what Taleb calls his warning—is all about managing risk, not about waiting for it to surface. The fact that GMOs are a systemic entity is undeniable. Taleb is equally skeptical of all entities that carry systemic risk—like too-big-to-fail banks.
We don’t, as Taleb says, argue that a game of Russian roulette is safer with each empty barrel we find. It is, in fact, more dangerous.
