What's wrong with all this? GM products are the subject of a worldwide heated controversy, whose participants include doctors and scientists as well as peasant movements, international organizations and political leaders, and has led to arrests, violent repression and persecution against scientists that have dared to contradict the official discourse on biotechnology. Since the 1990's this debate has produced numerous books, television and newspaper reports, documentaries (both short and of full-length), scientific symposia, contentious international negotiations, and even protest marches and civil disobedience.
These GM crops do not yield more than their conventional non-GM counterparts, they are not more nutritional, and do not use less toxic agrochemicals. The majority were altered to be immune to a herbicide called Roundup, a product of Monsanto, and they are thus known as Roundup Ready. The rest produce their own pesticide, and are known as Bt crops. This soy and corn are used to make, among other things, flour, starch, cooking oil, high fructose corn syrup, biofuels and feed for the farm animals that give us meat, eggs and dairy.
When we say genetically modified we mean an organism whose genetic code, or genome, has had foreign genes inserted into it through genetic engineering. The process of genetic engineering tears down cell barriers in order to make genetic combinations that would have never happened in nature, and it's used in food and agriculture since the 1990's. There are actually tens of millions of hectares of farmland planted with GM crops in the world, the great majority of them in only four countries: the United States, Canada, Brazil and Argentina. Almost all these GM crops are soy and corn. The rest are mostly cotton and canola.
Ituzaingo is a population surrounded by soy fields that are systematically fumigated. The spray from these fumigations arrives at the doors of the houses.”
In 2008 Chemical Research in Toxicology published a study by Gilles-Eric Seralini, a French specialist in molecular biology and professor at the University of Caen, which indicates that Roundup is lethal to human cells. According to Seralini's research, doses far below those used on soy crops cause cell death in a few hours. “Even in doses diluted one thousand times, Roundup herbicide stimulates the deaths of human embryonic cells, which could cause deformations, miscarriages, hormonal, genital and reproductive problems, as well as different types of cancer”, Seralini told Argentine newspaper Pagina 12.
“He also emphasized that in solutions of between 10 thousand and 100 thousand times more diluted than in the commercial product it no longer killed cells, but it blocked their production of sex hormones, which could provoke in fetuses difficulties in the development of bones and of the reproductive system. He alerted about the possibility that the herbicide could be an endocrine disruptor, and called for new studies.”Biotechnology companies assure us that the toxin secreted by Bt crops is harmless to human beings and that it dissolves in the human digestive system. Today we know both statements are wrong.
Bt toxin was found in the blood of pregnant women and their fetuses, as well as in non-pregnant women, by doctors at Sherbrooke University Hospital in Quebec. Specifically, the study determined that the toxin was present in 93% of 30 pregnant women, in the umbilical cord blood of 80% of the fetuses, and in 67% of 39 non-pregnant women. The study has been accepted for publication in Reproductive Toxicology, a peer-reviewed journal.Research funded by the Italian government published in 2008 found that laboratory rats fed with Monsanto's Bt corn had abnormally high IgE and IgG antibodies, something that is typically associated with allergies and infections. They also had elevated levels of interleukins, which is associated to various diseases in humans, from rheumatoid arthritis and osteoporosis to multiple sclerosis and Lou Gehrig's. The animals also had abnormally high levels of T gamma delta cells, which is what happens in cases of asthma, childhood food allergies, and juvenile arthritis.
