“10 ‘reasoned’ responses” to “10 reasons we don’t need #GMOs”

/ Cami Ryan, PhD / 45 Comments

You may have run across this article “10 Reasons We Don’t Need GM Foods” on the FoodConsumer website.  It’s been making its rounds on social media (Facebook and Twitter). I would like to address some of the inaccuracies in this article – point by point:

1. GM foods won’t solve the food crisis

Well, surprisingly enough, I agree with this one.  Or at least with the statement: GM foods ALONE won’t solve the food crisis. GM foods and genetically engineered (GE) crops aren’t a silver bullet in resolving problems with food security.  I refer to Mark Lynas (former Greenpeace activist and author) who said in a recent talk he gave at Cornell University:

“[GE/GM] cannot build better roads or chase away corrupt officials. But surely seeds which deliver higher levels of nutrition, which protect the resulting plant against pests without the need for expensive chemical inputs, and which have greater yield resilience in drought years are least worth a try?” Mark Lynas (April 2013)

Hey, I’d say so.  It is important to note that the introduction of GE crops (in particular) has enabled wider adoption of “no-till” farming (see a farmer’s perspective on this).  No-till is a system which conserves soil moisture, prevents erosion, dramatically reduces nutrient and pesticide movement to streams and rivers, and reduces fuel use.  All good, in my opinion.

Did you know that if we still farmed using the inputs and techniques that we did in the 1950s, we would need millions (maybe even billions) more hectares available to produce what we produce today? Advances in plant breeding techniques, introduction of no-till practices, integrated pest management and adoption of genetically engineered crop varieties account for this rise in production.  This translates into higher productivity on less land.  We all win.   

2. GM crops do not increase yield potential

Seriously?! Hmmm.  Well, research suggests differently. The results of meta-analysis (that means a study that analyzed the results from MANY MANY other studies) published in a peer reviewed science journal in 2012 found that organic yields of individual crops were on average 25% percent lower than that of conventional yields.   Productivity in GM crops are purported to be anywhere from 7 – 20% higher than conventional varieties.  And, of course, context matters.  Different soil conditions in different parts of the world may be more or less conducive to a variety of production methods. Again, GE technology and GM crops are not a silver bullet by any means. But genetically engineered crops are an important technology in the food production toolbox. So, let’s not throw the baby out with the bathwater, OK?

3. GM crops increase pesticide use

If that’s the case, then how do you explain this interesting fact? Cotton farmers in India spray heavily to control for pests that damage production. Did you know that the application of pesticides to cotton in India is done by hand? With farmers walking through their small cotton fields using backpack sprayers? The adoption of GM cotton in India has reduced the number of pesticide applications per season by 50%. It is estimated that more than 2 million fewer cases of pesticide poisoning are occurring on an annual basis which saves the Indian government US$14 million (Smyth 2013, Herring 2009).

Want a first world perspective on the whole GM and pesticide use issue? Check out Applied Mythology‘s “The Muddled Debate on Pesticides and GM Crops.” Pesticide use is lower. Combine that with other economic and environmental benefits (refer to #1 and #2)… it’s a good thing.

4. There are better ways to feed the world

Let’s re-phrase this so that it’s a bit more accurate: “There are “many” ways to feed the world”

Absolutely.  A million of them.  Food security is a complex problem that requires a multi-faceted approach in resolving the political and economic issues that come with feeding a growing world population.  Again, GE and GM crops are very important technologies in the food production toolbox…

I mentioned the “baby” and the “bathwater” already, didn’t I?

5. Other farm technologies are more successful

Farming is complex. I don’t know ANY farmer who is not up against making a hundred decisions in a given day.  Just ask a producer (grain, livestock, organic, conventional): Ryan Goodman, Brian Scott, Emily Zweber, Carrie Mess… Again, this is not an all or nothing scenario. Many factors go into the strategic management at the farm level.  And its never as simple as saying that GMO is ‘bad’ and organic is ‘good’ or vice versa. It’s more than just picking a production method.

6. GM foods have not been shown to be safe to eat

I hear this a lot and I have to remind everyone that nothing is 100% safe. Nothing. NO food. You can test organic, conventional and GM for the next 500 years and there will never ever be “absolute proof” that a food produced a certain way is 100% safe. That’s not how things roll here in the ‘real world’. The food value chain is long and involves lots of actors.  Lots can happen. Take for example the Maple Leaf Foods listeria crisis in 2008 (23 confirmed deaths). Then there was the XL Foods e.coli incident in 2012 where 18+ people were taken ill when they ingested tainted meat. And the anti-GM folks get a bit hot under the collar when I mention this one:  almost 4000 people were affected and 53 died from a rare strain of e.coli in sprouts that were produced on an organic farm in Germany in 2011.

There have been some food-related tragedies.  But there is no documented evidence of harm to human health or deaths from consumption of GM foods since they were introduced to the market two decades ago. None. Here are TWO studies (US and EU – and there are more) that attest to the safety of GM foods (NRC 2004, EC 2010, more here (scroll down)). GE crops or GMOs have been the most heavily tested food products in the history of our regulatory system.

7. People don’t want GM foods – so they’re hidden in animal feed

I wonder who thought this little gem up.  GM foods aren’t “hidden.” And they are certainly not “hidden” in animal feed.  Livestock producers use corn and soybean as a base for animal feed, all over the world (including the the European Union where GE soybeans are exported from the US and Brazil for animal consumption). As of 2012, there has been a 100-fold increase in the planting of biotech crops since 1996.  In the US alone, between 67% and 94% of all acreage attributed to corn, soybean, cotton and canola are genetically engineered. Nothing is “hidden” here… genetically engineered crops are ‘front and centre’ in world agriculture production.  Biotechnology is the fastest adopted crop technology in the history of modern agriculture (James 2012).

8. GM crops are a long-term economic disaster for farmers

Wow. That sounds scary.  Yes, GM seed prices are higher than that of conventional seeds.  But farmers that utilize the technology do so because they get higher yields and extract higher margins.  Just ask Brian Scott: “I can get a premium price for the soybeans we grow to be used as seed by other farmers next year.” If you ask Brian, he is neither “dependent” on the technology nor is he a “slave to ‘big ag'”.   Rather he (and other producers like him) are making economic decisions at the farm level based on input costs and projected market outcomes.  And don’t kid yourself. These folks don’t make these decisions at the expense of the land.  They *care* about the environment (environmental benefits: see #1).  They are not about to willfully destroy land that has been farmed by them and their ancestors – and potentially their children and children’s children – for generations.

9. GM and non-GM cannot co-exist

There’s that word again – – – “contamination”.  It’s an ugly word with ugly connotations.  Did you know that we already operate in a segregated agriculture and food system?  If you want, you can choose to eat organic.  It’s all labeled in your grocery store.  Organics standards were adopted by the Canadian Food Inspection Agency in 2009 in Canada.  These standards are enforced by organic inspectors through accredited certification bodies all over the country. Contamination? Organic farm and crop certification is based on the production methods used, NOT on the purity of the end product. So, nothing would happen to an organic grower or his produce if (in the highly unlikely event that) trace amounts of some other variety were found (BTW – there is no testing in organic crops). Organic growers will never lose their organic certification (unless, of course, they are shown to be intentionally growing ‘non-organic’ produce or crops and sending them to market as ‘organic’).

10. We can’t trust GM companies

Don’t believe everything you read. Syngenta, Dow, Bayer, Monsanto and other ‘big ag’ companies are just that – companies. They are profit-motivated and generate revenues to cover the costs of doing business and to provide a return for their shareholders. These companies, and others like Apple or MicroSoft, make no secret of that. And isn’t that the tenet of any business – big or small? Companies step into the space where the public sector can’t and won’t – they bring the products downstream to the market. Did you know that the time that it takes to put a product through the regulatory system has almost tripled in the last 20 years (13 years and $140 million US)? And just to clarify, the regulatory system is no more robust than it ever was. But the political pressures that have been placed on governments by interest groups have forced a ‘slow down’ in the regulatory process. This means more costs. And, right now the only companies that have the resources to navigate the costly and complex regulatory processes are big ag.

The whole “David and Goliath” thing (small defenseless farmer vs big ag company) gets wayyyy overblown in the anti-GM rhetoric.  Like I said before, don’t believe everything you read.  Like ’em or not, ‘big ag’ companies are the only ones that can take these technologies to the marketplace where society can extract value from them.  Who else? Universities and public research institutes? I don’t think so.  At least, that’s not where I want *my* tax dollar going. These multinational ag businesses invest the dollars in the research and product development and they have a right to protect that investment for a limited period of time. It’s how our patent system works – for EVERYONE.

We live in a privileged world; one where food is plentiful and varied and one that affords us this seemingly ‘aesthetic’ relationship with what and how we consume. We have turned our backs on the functionality of food and entered into this realm of ‘food snobbery’ where the ‘food police or elites‘ (as Jayson Lusk refers to them) seem to rule the world.

On a final note: For every 10 reasons cited suggesting that we don’t need GMOs, I can list 100 or more of why we *do* need genetically engineered crops and GM food.

Mythbusting 101: “Don’t say it – spray it”

/ Cami Ryan, PhD / 7 Comments

In my bio, I claim to be a ‘mythbuster’ of sorts.  I like to clear up misconceptions about agriculture and food production. It amazes me what kind of nonsensical information gets circulated and how readily some people believe it.

Today is the first in my series entitled “Mythbusting 101.” I was inspired by a discussion on Facebook that centred around one particular photo.  Brian Scott (The Farmer’s Life) circulated the photo with the comment: “I hate out-of-context garbage like this. Especially when I see how many people *like* and *share* these things. There is absolutely no context given as to what is going on here.”

I couldn’t agree more.

392869_234790246646018_1396286088_n

Mythbusting 101: When you see pictures and words combined like this, channel your inner skeptic. This photo is grossly misleading (and this is just one example of many that are out there).

Although we can’t find the original source of the photo (it was posted on FB through Anti-Media), we are certain that this guy is not spraying water. He is spraying a pesticide. Labels on pesticides provide instructions on how to SAFELY apply these products (including ORGANIC approved pesticide products as they are toxic too). This ‘gear’ is standard protocol when administering any pesticides to crops (organic or otherwise). And… this photo has NOTHING to do with GMO foods, or labeling for that matter. In fact, this man appears to be spraying flowers or nursery stock of some kind.

A photo with the accompanying text like this is an example of what I call ‘misinformation in action’. Someone (a ‘myth-monger’ as I refer to them) is intentionally (sometimes unintentionally) misleading people.

We need to think critically about how food makes it from the field to our plate. Food is a very personal thing. That means that we need to also think critically about what we see and read about ag and food production. We should ensure that we are interpreting the information correctly and that the information *we* share with others is accurate.

If you are not sure, ask someone. Ask a farmer. Ask Brian. And make sure to check out the comments below. I was delighted to have others weigh in with their opinions on this matter.  I like to call this ‘crowd-sourced mythbusting.’ :O)

Is Organic Food Better for You? Article by Mattern from University of Saskatchewan’s “The Sheaf”

Is Organic Food Better for You? A Critical Look at Organic Claims

 

– Ashleigh Mattern, The Sheaf: Univ. of Saskatchewan Student Newspaper, July 13, 2010.

The average North American grocery shopper has only a vague idea of how their food is grown, processed and transported to the supermarket.

 

The agriculture-to-grocery-store process is a complex machine that seems almost like magic: row upon row of shiny fruits and vegetables appear in the store every day in seemingly unending amounts. But it’s not magic, and many consumers are aware of this, and becoming wary of the great agriculture machine.

 

For some, organic foods seem to be the answer. Producers tout organics as the answer to the toxic, mutant fruits and vegetables that crowd the grocery store. They encourage consumers to pay a little more for peace of mind, painting organics as the safer alternative.

 

Organic producers say their food tastes better, is more nutritious, and is better for the environment. But in an effort to be wary of salespeople’s pitches, I decided to get to the roots of claims about organic foods.

 

Price
Initially, one of the biggest barriers for me when considering buying organic foods was the price. To compare what I might spend on an average grocery trip, I took my regular grocery list to an organic market.

 

The biggest surprise for me was the price of milk. My boyfriend and I drink a lot of milk, and so I buy four litres a week. A four-litre jug of organic milk cost a whopping $12.19, compared to the Co-op brand four-litre I usually buy at $3.99.

 

I would have spent about $60 on organics, compared to about $30 on conventional foods. That’s a pretty big price difference, and no small difference for a student, but most people don’t buy all their food organic. Organic fruits and vegetables have the most competitive prices, and the organic lemons were actually 10 cents cheaper.

 

As more organic producers get into the market, the prices will continue to drop, as well. For a fairly well-off family, paying an extra dollar for organic ground beef may seem worth the perceived added benefits. Unfortunately, I had only started my journey into the world of organic food. Soon enough, price was the least of my worries.

 

Nutritious and delicious?
Proponents of organic food say it has more vitamins and nutrients and it tastes better. The taste factor may never be scientifically settled as it is completely subjective, but at least one study has determined the nutritious value of organic foods: they’re no more nutritious than non-organics.

 

A study published in the American Journal of Clinical Nutrition surveyed over 50,000 published articles about organic food, focusing on 55 studies that met their scientific standards.

 

They found more nitrogen in conventional crops and more phosphorus in organic crops, but concluded that “there is no evidence of a difference in nutrient quality between organically and conventionally produced foodstuffs.” There were fewer published studies on livestock, but of the studies they did have, they found no nutritional difference between organics and non-organics.

 

Pesticides, herbicides and fertilizers, oh my!
There are strict regulations on what foods can be labelled organic. When talking to the owner of an organic market recently, he said “no pesticides, herbicides or fertilizers” can be used, but this simply isn’t true. Organic farmers can’t use synthetic products on their crops, only “natural” products. The seemingly logical conclusion is that any natural pesticide or fertilizers is safer than a synthetic one, but again, this isn’t true.

 

One fertilizer some organic farmers use is manure. What the person selling you organic food won’t tell you is that food grown in a manure-based fertilizer has a higher chance of containing E. coli because the virus thrives in the bellies of cows.

 

The bottom line is that nearly all pesticides are bad for humans, whether they’re natural or synthetic. Luckily, the amount of harm they can do has a direct relation to the amount of pesticide you’re exposed to. The Extension Toxicology Network explains that pesticides decline over time. Residues left on the food after washing and processing break down eventually, and the levels of pesticides and herbicides on the food is “well below legal limits” by the time the food reaches the grocery store. Organic food proponents say there have been no studies showing low levels of pesticides and herbicides do no harm, but this is also not entirely true.

 

Pesticides are anything used to defend against fungi, insects and predators. A little known fact is that most fruits and vegetables produce their own pesticides. A paper written by Bruce Ames, who invented the Ames test to determine whether a compound is carcinogenic, says the average American ingests 1,500 mg of natural pesticides per day, compared to 0.09 mg of synthetic pesticide residues.

 

“The amounts of synthetic pesticide residues in plant foods are insignificant compared to the amount of natural pesticides produced by plants themselves,” the paper says.

 

Touting the claim that the effects of exposure to low levels of pesticides has not been studied, one organic-supporting website suggests that “In the absence of this information, the safest course is not to expose yourself to chemicals designed and proven to kill other forms of life.” Sticking with this strain of logic, should we stop eating all fruits and vegetables? Natural pesticides may not be synthetically designed, but they certainly have been proven to kill other forms of life.

 

Genetically modified foods
As with irradiation, the rejection of genetically modified foods seems to stem from fear and misunderstanding. “People have to understand that all the foods we have right now—have all undergone genetic modification; that’s where you take one cultivar and cross it with another cultivar,” said Dr. Nicholas Low, a professor with the U of S’s College of Agriculture and Bioresources. “We want them to grow fast; we want the tomatoes to grow big- When people talk to me about GM, I don’t think they understand that everything we eat has been modified.”

 

He says the difference between the old fashioned way of crossing cultivars and genetically modifying it by moving genes from one plant to another is that a very specific modification is made. In fact, Low says “These genetically modified foods are safer because we know the genome of these plants.” Basically, no changes happen by accident.

 

Since GM foods can gain genetic materials from other plant species, some consumers and anti-GM groups worry this means allergens might end up in non-allergenic foods, for example, genes from a nut used in grains. In fact, this has been tried: in 1996, the seed company Pioneer Hi-Bred International attempted to use genes from the Brazil nut to make their soybeans hardier.

 

Pioneer dropped the project when the testers pointed out the folly of using a known allergen to enhance other foods.

 

GM foods aren’t developed over night. They go through years of trials and testing guided by the Canadian Food Inspection Agency. If it’s not fit to be consumed, it won’t be approved.

 

That’s not to say there aren’t risks involved in the use of GM foods. Critics have legitimate concerns about the possibility of GM foods having an impact on biodiversity or the potential effects of horizontal gene transfer, where genes from the modified crops would transfer into wild crops. So far, GM foods aren’t in wide enough use to know if horizontal gene transfer can happen or to say if they have an effect on biodiversity (in fact, at least one scientist believes GM crops might promote biodiversity). But we have to ask ourselves if the potential risks outweigh the known benefits.

 

A complete rejection of genetically modified foods might be a mistake. “GM foods have the potential to solve world hunger and maltnutrition problems and protect the environment,” said Low. “We could use our foods to help to prevent disease rather than having medicine as a the middle man.”

 

Flat-out rejecting GM foods might mean rejecting better nutrition and feeding the world’s growing population. Perhaps the better path is to continue investigating this relatively new science, but tread carefully.

Fresher is better
The Dieticians of Canada and Canada’s Food Guide have no official stance on organics, simply suggesting to eat a wide variety of fresh fruits and vegetables.

 

But organic foods are also not all the proponents make them out to be. It’s not healthier or safer, and if used improperly, natural pesticides, herbicides and fertilizers are just as dangerous for the environment and humans as synthetic products.

 

The process of bringing organic food to your table is every bit as complicated as it is for conventional foods. The best way to feel better about your food choices is to learn about agriculture and how the food gets from the farm to your local grocery store, not by simply assuming organic food as the better choice.

 

“If you say, ‘I choose to eat organic foods,’ that’s fine,” said Dr. Nicholas Low, “but if you say, ‘I eat organic foods because it’s better for me,’ I have a problem with that.”

 

Next time you’re trying to decide between an organic or conventional food item, you might want to consider your reasons behind the choice a little more carefully.
