New Study Gives Genetically-Modified Crops a Failing Grade

While Monsanto and other companies involved in creating and distributing genetically-modified (GM) seeds have been citing the supposed environmental benefits for many years, a new Canadian study gives GM crops a failing grade. The study by the Canadian Biotechnology Action Network (CBAN), indicates that genetically-modified crops fail on multiple levels: they do not reduce pesticide use or protect biodiversity regardless what companies continue to claim.

In the report “Are GM Crops Better for the Environment?” released on May 22, researchers examined twenty years of data to determine whether genetically-modified crops reduced pesticide use or protected biodiversity in Canada. Not only did CBAN find that GM crops did not live up the environmental claims, instead they aggravated the same problems the corporations claim they improved. Not only did GM crops not reduce herbicide use, but there has been a 130 percent increase in use of them over the last 20 years in Canada.

According to Lucy Sharratt, spokesperson for CBAN, “There is a strong correlation between the expansion of GM herbicide-tolerant crop area and the increased use of herbicides in Canada. This environmental impact was predicted twenty years ago and needs to be urgently addressed to protect ecosystems and human health.”

The study also found that the use of glyphosate-based herbicides in Canada tripled between 2005 and 2011, and is associated with the cultivation of GM glyphosate-tolerant corn, canola, soy and sugar beets. Glyphosate is now the highest-volume pesticide active ingredient sold in Canada, followed by 2,4-D and glufosinate ammonium. CBAN’s study arrives after many other studies found links between glyphosate exposure and cancer, sterility, obesity and other serious health concerns.

In March 2015, the World Health Organization’s International Agency for Research on Cancer determined glyphosate as “probably carcinogenic to humans”.

Another study published in the peer-reviewed journal Entropy found that glyphosate—the main ingredient in Monsanto’s “Roundup” weed killer may be linked to gastrointestinal disorders, obesity, diabetes, heart disease, depression, autism, infertility, cancer and Alzheimer’s disease.

Other research from the University of Caen, France, found that animals exposed to Roundup experienced an increased impairment in sperm structure and reproduction.

Still more research published in the International Journal of Environmental Research and Public Health found a link between some pesticides and a significantly increased risk of non-Hodgkin’s lymphoma—cancer of the lymphatic system. In this meta-analysis, scientists evaluated 44 studies, 80 active ingredients in 21 classes of chemicals and found that exposure to glyphosate the main ingredient in Roundup doubles the risk of this deadly cancer.

CBAN’s report also examined the impact of GM crops on biodiversity and concluded that:
· Insects that have developed resistance to GM insect-resistant (Bt) crops are spreading across the world.
· North America has lost 90 percent of its Monarch butterfly population due to habitat destroyed by glyphosate used on genetically-modified glyphosate-tolerant corn in the U.S.
· GM contamination in Canada prevents organic farmers from growing canola, and may have reduced genetic diversity in both canola and flax seed.
· GM organisms are difficult to control once they are released into the environment.

Says Lucy Sharratt: “We need to make sure we don’t continue using ineffective and destructive strategies. At the moment we’re set to simply accelerate herbicide use along with the problems of pest and weed resistance and biodiversity loss.”

As far as the GMO shills and paid Monsanto propagandists here trying to discredit the Anti-GMO scientists in a hundred countries by trashing the "Seralini Study", for one thing, there have been studies by a huge number of INDEPENDENT experts (not the bought and paid for lab rats working for or funded by the US based GMO mafia), and the other point, the Seralini study, which found serious problems with GMOs in an animal health study, was not in any way "discredited." What happened is that the biotech industry put enormous pressure on the publisher of the study to retract the study and forced onto the publication a new editor who was a former employee of Monsanto. The study was then "retracted" for no scientific reason and the the publication was widely condemned by a large part of the scientific community for allowing corporate interference with science. The Seralini study has since been republished in another reputable, peer-reviewed journal and it is considered the best long-term feeding study on animals and GMOs that has ever been conducted. Oh, by the way, the study found a whole range of very troubling negative impacts on rats from being fed GMOs over a two year period. Of course, the biotech companies could easily replicate this study if they wanted to prove the safety of GMOs, but they have assiduously avoided such work for over twenty years as they know what they results will be. The desperate crowd on these blogs trying to legitimize GMO's are either on the payroll of

The toxins associated with GMO should never be tolerated. NEONICOTINOID PESTICIDE neurotoxins are absolutely the main factor causing the collapse of bee and pollinator populations along with other lethal chemicals, Agent Orange herbicides, glysophate, etc. When these poisons are banned as they were in Europe the bee populations start to recover. GMO neonicotinoids, roundup etc. MUST BE BANNED OUTRIGHT and all the farmers along with USDA, Biotech and chemical companies told to cease and desist from what they are doing.

An even scarier prospect: the "BT" version of GMO soybeans and corn, (basically pesticides engineered directly into the plant )

The "BT toxin" gene is put into the DNA of the corn in order for it to manufacture its own toxins that kill pests. The BT gene originated from a soil bacteria that also infiltrates the microflora (friendly digestive bacteria) in your gut. The Bt gene converts the microflora in your intestine into toxin-manufacturing machines.

So, to be clear, eating GMO corn products can cause your gut (which is primarily responsible for keeping you healthy) to turn into a breeding ground for tiny little pesticide factories inside your body, actively creating toxins which are designed to kill living things. These toxins are found in the blood and are readily transferred across the placenta to developing babies in the womb.

GMOs do not increase yields, and work against feeding a hungry world.

Whereas sustainable non-GMO agricultural methods used in developing countries have conclusively resulted in yield increases of 79% and higher, GMOs do not, on average, increase yields at all. This was evident in the Union of Concerned Scientists' 2009 report Failure to Yield―the definitive study to date on GM crops and yield.

GM crops and their associated herbicides can harm birds, insects, amphibians, marine ecosystems, and soil organisms. They reduce bio-diversity, pollute water resources, and are unsustainable. For example, GM crops are eliminating habitat for monarch butterflies, whose populations are down 50% in the US. Roundup herbicide has been shown to cause birth defects in amphibians, embryonic deaths and endocrine disruptions, and organ damage in animals even at very low doses. GM canola has been found growing wild in North Dakota and California, threatening to pass on its herbicide tolerant genes on to weeds.

By mixing genes from totally unrelated species, genetic engineering unleashes a host of unpredictable side effects. Moreover, irrespective of the type of genes that are inserted, the very process of creating a GM plant can result in massive collateral damage that produces new toxins, allergens, carcinogens, and nutritional deficiencies.

GMOs cross pollinate and their seeds can travel. It is impossible to fully clean up our contaminated gene pool. Self-propagating GMO pollution will outlast the effects of global warming and nuclear waste. The potential impact is huge, threatening the health of future generations. GMO contamination has also caused economic losses for organic and non-GMO farmers who often struggle to keep their crops pure.

GMOs increase herbicide use. Most GM crops are engineered to be "herbicide tolerant"―surviving deadly weed killers. Monsanto, for example, sells Roundup Ready crops, designed to survive applications of their Roundup herbicide. Between 1996 and 2008, US farmers sprayed an extra 383 million pounds of herbicide on GMOs. Overuse of Roundup results in "superweeds," resistant to the herbicide. This is causing farmers to use even more toxic herbicides every year. Not only does this create environmental harm, GM foods contain higher residues of toxic herbicides. Roundup, for example, is linked with sterility, hormone disruption, birth defects, and cancer.

GMO is a dangerous poison. Eating genetically modified corn (GM corn) and consuming trace levels of Monsanto's Roundup chemical fertilizer caused rats to develop horrifying tumors, widespread organ damage, and premature death. rats exposed to even the smallest amounts, "developed mammary tumors and severe liver and kidney damage as early as four months in males, and seven months for females." The animals on the GM diet suffered mammary tumors, as well as severe liver and kidney damage. Everywhere GMO is being grown, food allergies, disorders such as autism, reproductive disorders, digestive problems, and others have been skyrocketing in the human populations.

There has been a drastic decline of crop-pollinating insects all over the world, and what this means for the future of the world's food supply. Wild pollinators like bumblebees, butterflies, and beetles are basically disappearing. GMO industrial agricultural practices are causing this insect genocide. Pollinating insects in general, which include a wide range of insects and other animals, are simply vanishing from their normal habitats and foraging areas. That lower diversity and lower abundance of wild insects means less fruits and destruction of the diversity of plants and their fruits worldwide.

GMOs cross pollinate and their seeds can travel. It is impossible to fully clean up our contaminated gene pool. Self-propagating GMO pollution will outlast the effects of global warming and nuclear waste. The potential i
