MYTH: GMOS HAVE BEEN AROUND FOR THOUSANDS OF YEARS
Genetic modification is different from traditional breeding and presents its own set of unique risks. The term “genetic modification” really refers to the unnatural process of taking genes from one species and using a special gun, viruses, or bacteria to inject it into another organism. This process could never occur naturally in nature. So the genetic modification we’re talking about when it comes to seeds and genetically engineered ingredients in our food—we’re talking about this completely unnatural process.
Traditional breeding, known as selective breeding, has been around for thousands of years, where people can cross breed, for instance, tomato plants with favorable qualities, like great flavor, natural disease resistance, etc., with another tomato plant. Thisis not what happens when we’re talking about genetically modified seeds. Most GMOs in use now are created to withstand heavy herbicide sprayings. The company that creates the seed also sells the chemical you use on it. It’s a package deal.
When starting your own garden, make sure to look for organic seeds from companies that take the Safe Seed Pledge. These companies go to great lengths to avoid purchasing seed from companies that promote GMOs.
Myth: We Need GMOs To Control Weeds And Pests
In an ironic twist, GMO technology has actually made pest problems more severe. Most of the GMO seeds currently in use were genetically manipulated to either produce their own pesticides inside of the plant or to withstand heavy doses of chemical pesticides that would normally kill the plant. In 2012, there were 154 million acres of genetically modified soy, corn, alfalfa, cotton, canola, and sugar beets developed to withstand chemical herbicide dousing. About a third of that land now harbors superweeds, problem plants that won’t die when sprayed with the GMO’s intended weed-killing chemical.
Most are designed to withstand high doses of glyphosate—the active ingredient in Roundup. Weeds quickly became resistant to glyphosate, meaning heavier—and more frequent applications—are required to try to combat weeds. Professor Chuck Benbrook, PhD, a research professor at Washington State University, recently found that between 1996 and 2011, GMO technology actually increased herbicide use by 527 million pounds—that’s an 11 percent bump. In fact, for every fewer pound of insecticide used, four pounds of herbicides are used. GMOs are not living up to the promise. It’s that simple.
Myth: GMOs Reduce Farmers’ Dependence On Older, More Toxic Pesticides
Dow Agrosciences has asked the United States Department of Agriculture to approve a new generation of GMO corn and soy crops designed to withstand heavy doses of 2,4-D, an old, toxic weedkiller because current GMOs are failing. There’s been an explosion of superweeds that are no longer killed with glyphosate and 21 weed species are now resistant. Millions of acres of farmland are now abandoned due to the GMO/superweed problem; some farmers are paying up to $150 an acre per hour for hand weeding.
Myth: GMO Ingredients Are Safe To Eat
GMO ingredients have never been adequately tested for long-term impacts on public health despite hitting the market in 1996. There are about 600 studies focusing on the composition of genetically engineered foods, looking at things like calories, protein, fat, and vitamins. These mostly industry-funded studies are generally performed to show the Food and Drug Administration that the food is nutritionally comparable to non-GE foods, or to convince livestock farmers that GE feed is on par with non-GE feed. Both types of studies have next-to-nothing to do with human health and safety, Benbrook warns.
Some of the very few studies looking at shorter-term health impacts suggest cause for concern. A carefully designed meta-analaysis of 19 longer-term published studies looking at mammals found those fed genetically engineered corn or soybeans experienced kidney, liver, and bone marrow damage, potential indicators for chronic disease. GMOs are also implicated in skyrocketing food allergies rates and Roundup, the chemical often sprayed on GMOs, has been linked to certain cancers, DNA damage, premature births, and ADHD. Warren Porter, PhD, professor of environmental toxicity and zoology at the University of Wisconsin, Madison, analyzed government data on glyphosate in the environment and found cause for concern. The levels could lead to accumulated levels that could alter endocrine-mediated pathways, leading to obesity, heart problems, circulation issues, and diabetes, as well as lead to low level glyphosate levels have also been linked to immune system damage, birth defects, cell death, and learning disabilities.
It’s not good for animals, either. In a recent study published in the Journal of Organic Systems, Australian and U.S. researchers found pigs fed genetically engineered feed were much more likely to suffer from severe stomach inflammation and heavier uteri, a condition that could signal endometrial cancer, endometriosis, abnormal thickening, or gynecological polyps—all things that could affect fertility.
Myth: GMOs Are Safe For The Environment
Myth: GMO Technology Is An Exact Science
Although improving, GMO technology is still young and not very reliable. When inserting a foreign gene into a plant, there’s a 1 in a 100 trillion chance of getting the insertion into the same place twice, according to farmer and GMO researcher Howard Vlieger. The desired characteristic inserted into the plant could have other traits, including ones we haven’t even discovered yet. We don’t know how that could impact human health, but GMOs are already implicated in skyrocketing rates of food allergies.
Since biotechnoligists only know a sliver of what there’s to be known about the genome of any crop species and about the genetic, biochemical, and cellular functioning, even inserting genes at a site deemed to be “safe” could cause a crop to become toxic or feature reduced nutritional value, or reduce it’s ability to resist disease, pests, drought, or other stresses, according to an Earth Open Source report.
