Monsanto glyphosate (Roundup) is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses that are known to compete with commercial crops grown around the world. It has several advantages over many herbicides in that it breaks down in the soil into non-toxic organic molecules, reducing or eliminating contamination of groundwater and lower soils.
Monsanto has developed genetically modified (GMO) grains that are resistant to glyphosate, so that agriculture can apply the herbicide to kill the competitive weeds while not harming the crop. This allows farmers to suppress the weeds while allowing better production out of the grain crop.
Whatever the benefits of Monsanto glyphosate, GMOs and the herbicide are tied together in many minds. And there has been an ongoing effort by many people to claim that glyphosate causes cancer. But let’s look at the science, because maybe we’ll get some information.

Real science is hard. It takes lots of high quality evidence to support it. That evidence needs to be published in real journal. It needs to be repeated. And it has to be open to criticism and analysis. GMO science, the study of genetically modified organisms used for crops and food, shows us that GMOs are safe.
The hard work and intellectual challenges to form a scientific consensus about the safety of GMO crops and foods isn’t something that appeared out of the ether. These individuals didn’t suddenly wake up one day and proclaim from the ivory tower that GMO science says that GMOs are safe. Not even close.
Science has provided substantial evidence supporting the assertion that GMO’s are safe. GMO refusers have provided precious little evidence, save for Cherry Picking, Special Pleading, and a few Strawman Arguments. Oh, and the occasional Poisoning the Well with the Monsanto shill accusations. Sometimes the GMO deniers will resort to the Naturalistic Fallacy that things that grow “naturally” ought to be the way foods should be – this ignores the fact that we’ve been genetically manipulating our food for ten thousand years. We’re just better at it today, but the DNA is still the DNA.
Like I said in another article, “The typical pseudoscientist will use logical fallacies to state very definitively that “it’s proven.” It’s the same whether it’s creationism (the belief that some magical being created the world some small number of years ago), alternative medicine (homeopathy, which is nothing but water, has magical properties to cure everything from cancer to male pattern baldness), or vaccine denialists. The worst problem is that in the world of the internet, if you Google these beliefs, the number of websites and hits that seem to state that they are THE TRUTH™ overwhelm those that are more skeptical or critical.”
So, using an open, but critical mind, the evidence is overwhelming – the GMO science says it’s safe for human consumption.

Of all the icons of American life, buying Girl Scout cookies is one of the annual obligations of life. Americans buy these cookies from parents selling for their daughters, from uniformed Girl Scouts in front of the grocery store, or from a family member. I can’t wait for my annual infusion of Samoas, the Girl Scout’s take on the macaroon. Caramel and coconut – how could we go wrong? Well, apparently, I need to spend more time to consider the issue of Girl Scout cookies and GMO ingredients.
To be honest, I’m more concerned about the calories in each. But here we are.
Late last year, The Girl Scouts of the USA made an announcement in regarding Girl Scout cookies and GMO products:
At the current time, there are genetically modified agricultural crops (GMOs) in some Girl Scout Cookies based on a range of market-related factors and depending on specific cookie recipes. In some markets, the specialty-ingredient Girl Scout S’mores sandwich cookie baked by Little Brownie Bakers is made with ingredients that are verified as not containing genetically modified organisms. Girl Scouts recognizes that many people have concerns regarding GMO ingredients, and we monitor member and consumer opinion on this matter while simultaneously addressing industry trends, scientific trends, and, of course, consumer preference.
Sadly, the Girl Scouts have decided to cave in to the demands of certain groups that GMOs bring some sort of harm to consumers. Of course, the usual anti-science groups jumped into the fray. March Against Monsanto, a group that ticks off the most of the junk science checklist with their anti-GMO, anti-vaccine, and anti-fluoridated water arguments, were ecstatic with the announcement. They chimed in that,
There was a time recently in the United States when Non-GMO and organic packaged foods were surprisingly rare, so much so that choice was a virtual non-entity and entire communities of people have no access to non-GMO options.
But now, non-GMO has officially gone mainstream: one of the country’s most recognized institutions, the Girl Scouts of the USA (formerly known as America) has announced its first-ever (officially speaking, anyway) non-GMO cookie.
You can almost see the glee dripping from the announcement. Once again, let’s take a look at Girl Scout cookies and GMO safety. This change happened because of a lot of noise that signified nothing. Time to examine it again.

The safety of GMO crops to humans, animals and the environment has been well established. The scientific consensus clearly states that consuming bioengineered foods has no effect on your health. Clearly, you can grab an ear of GMO corn, put some butter and a sprinkle of salt on it, and you will eat it with no negative health effects. And you’ll have a giant smile across your face.
But the anti-GMO forces have attempted to move the target. They have tried to claim that GMO crops are less productive and cost more to produce. That’s beyond the scope of this article, though there is some pretty good evidence that there is higher yield for bioengineered crops.
One of the more annoying aspects of the anti-GMO complains is conflating the genetically modified crop with the GMO crop pesticide. Invariably, some someone will post a meme or discuss a trope that evolves from GMO food to glyphosate, the herbicide known as RoundUp. the conversation will lead to ridiculous conclusions that Monsanto (who manufactures glyphosate) is killing everyone by forcing farmers to use RoundUp with Monsanto’s own GMO crops which are resistant to glyphosate. It’s all Monsanto all the time when discussing GMO crop pesticide use.
A new paper was published last month that may or may not give us more information about pesticide use with GMO crops.

A few weeks ago, Gilles-Eric Séralini and his homeopathy loving coauthor published an article in Food and Chemical Toxicology that concluded that glyphosate (known as Roundup)-resistant NK603 GMO corn, developed by Monsanto, causes severe diseases such as tumors in rats. And usual anti-science websites bought into this nonsense, including the TV medical practitioner, Dr. Oz.
It’s time to remind everyone that the Séralini study was bogus, and that Dr. Oz is also bogus. Here we go.

One of the tropes of the anti-GMO movement is that nature does it better for food, a logical fallacy. In other words, they believe that our ancestors’ foods are somehow better than our GMO foods. Of course, this belies the fact that there are over ten thousand years of GMO foods – it’s really not something that showed up during the last century or so.
People seem to endow “nature” with a special status that is ridiculous. Evolution proceeds along a random process where environmental changes select for certain mutations over time (and yes, I’m oversimplifying the process), which is called natural selection. Moreover, there are random mutations that just occur that provide no benefit to the organism, although they might in the future because of some environmental change.
Nature has no goal. It has no guidance. It has no underlying value of good or evil. Unless you believe that some higher being controls it, and at that point, you’re a creationist, claiming that “nature” is better than the alternative is basically ridiculous.
So, we’re going to talk about how genetic modification has moved from the early days of waiting for a random, beneficial mutation to the modern world of genetic modification.

A pseudoscience pushing website (which occasionally tosses in stories about real science) is trumpeting a primary research study (published several months ago) that may, or really may not, indicate that plant GMO genes transfer to humans. They claim that DNA may survive intact in the digestive tract and show up in the bloodstream.
In case you’ve ignored this area of false controversy, genetically modified crops are foods derived from genetically modified organisms (GMOs). Of course, all types of agricultural breeding induces genetic modification, but in general, GMO usually implies actual manipulation of the genes.
Based on some of the worst science available, the anti-GMO activists have condemned GMO foods as being dangerous. Unfortunately for the anti-science side, there is actually no science supporting these anti-GMO claims, and the vast scientific consensus says that GMO foods are safe to humans, animals and the environment.

If you don’t know about the case of anti-GMO activists harassing Dr. Kevin Folta, Professor and Chairman in the Department of Horticultural Sciences at the University of Florida, I’ve written about it extensively over the past few months.
Dr. Folta is considered to be an expert in plant genetics including genetic modification of plants. He has been studying this field for nearly three decades, published extensively in real peer-reviewed journals, and has trained legions of graduate students. He should be considered a real authority figure in GMO research.
In 2012, Dr. Folta was “targeted” by a Freedom of Information Act (FOIA) request from an activist to get all of Dr. Folta’s emails about GMOs. If you are unfamiliar with this particular tactic, it is used frequently by climate change deniers to harass and bully climate change scientists.
This will be a repeating theme of this article – the science deniers who are harassing Kevin Folta are almost exactly the same as the science deniers who attack climate change scientists. They must be proud of this.

There is an evolving feeling that anti-GMO activists and climate change deniers are nearly the same. They both rely upon denialism (also known as pseudoskepticism), which is the culture of denying the established scientific consensus despite overwhelming evidence.
Admittedly, some of the denialism is based on political expediency. Climate change denialism is a fundamental aspect of many politically conservative voters across the world, but especially in the United States, where Republican legislatures in the United States have passed anti-anthropogenic global warming legislation.
But not to be outdone, the left-wing parties across the world have their own particular brand of science denialism–GMOs. Some may argue that vaccine denialism has a political component which is supported by some liberals, there’s also a lot of evidence that Republicans in the US have the same anti-vaccine belief. Setting aside the politically nuanced anti-vaccine groups, GMOs are the left’s version of climate change denial.
Anti-GMO activists and climate change deniers share some of the same tactics and strategies, even if they are, for all intents and purposes, at the opposite ends of the political spectrum.
They both tend to reject science. They both use the same character attacks on supporters. And they both are awfully good at cherry-picking data that buttresses their a priori conclusions. In other words, they look for the data to support their beliefs, rather than the scientific method which is to find what conclusions can be supported by the evidence.
Let’s look at something that just happened which should remove any doubt that anti-science believers use the same tactics, probably because they lack any evidence. It’s apparent that they all meet at some anti-science convention to receive training on how to do this best.

Scientific denialism (also known as pseudoskepticism) is the culture of denying an established scientific theory, law or fact despite overwhelming evidence, and usually for motives of convenience. Sometimes those motives are to create political gain for their supporters.
Two of the most annoying denier viewpoints are the darlings of the right wing: evolution denialism and global warming denialism. The former is more commonly known as creationism and is mostly an American phenomenon, though it is known in other countries. In the USA, creationism is a fundamental part of the Republican Party strategy across the country. In fact, much of the anti-evolution legislation pushed by Republican legislatures in the United States has an anti-global warming component.
Although denial of anthropogenic global warming and evolution tend to be the domain of the right wing, the left-wing have their own particular brand of science denialism–GMOs (though some think I should include vaccine denialism too). Global warming deniers and GMO opponents share some of the same tactics and beliefs, even if they are the opposite ends of the political spectrum.
