Earlier this month a controversial study by French scientist Gilles-Éric Séralini linking genetically modified corn to cancer was retracted by the peer-reviewed journal that published it.
The retraction, primarily based on the post-publication evaluation that its findings have been inconclusive, produced such explosive commentary that there is currently a Wikipedia webpage dedicated to the so-called Séralini Affair. The event and its ongoing fallout affirms that handful of agricultural subjects are as politically charged as the purported safety of genetically modified organisms (GMOs).
Are these fabricated substances–which seem in almost all very processed foods–killing us?
1 cohort of advocates–a cohort that triumphantly promoted the Séralini review when it hit the presses in September of 2012–thinks they just may well be. It insists that GMOs are untested and unregulated agents that cause–or contribute to–serious well being problems. Relying heavily on the precautionary principle (while stoking an inveterate hatred of the biotech giant Monsanto), these skeptics note, as Tom Philpott explained in Mother Jones, that when it comes to GMOs, consumers are “eating in the dark.”
One more group–one that rejoiced when the Séralini piece was retracted–contends that not a single research has however linked GMOs to human overall health problems. Citing the possible of GMO crops to accomplish higher yields on significantly less acreage, these supporters get solace in the assessment of a number of scientific organizations–including the American Association for the Advancement of Science, the American Healthcare Association, and the National Academies–that have deemed GMOs secure to consume.
Due to the fact this debate is trapped in the vice of the precautionary principle–after all, there is no identifiable second when long term safety of anything can be assured–it always lacks an finish stage. Discussions are at this juncture tiny much more than media theater. This is unfortunate. It’s unfortunate because our popular obsession with the perpetually elusive overall health consequences obscures a deeper reason we may well want to be wary of GMOs: it is not human well being per se that’s at stake with this technology–it’s the overall health of the planet.
Rather of dubious overall health claims, concerns more than GMOs need to center on the culprits of corn and soy. These are the two most broadly planted and ecologically troublesome crops grown in the United States. And 88 % of the corn and 94 % of the soy grown on US land just so transpires to be genetically modified.
Corn and soy are monocultural staples that come with measurable environmental consequences. With each other, they account for much more pesticide use–up to 81 % of all pesticides sprayed in some years–and are the country’s most significant customers of nitrogen fertilizer, which runs off and damages aquatic ecosystems. Corn needs up to 120 lbs of nitrogen fertilizer per acre. Kale calls for as minor as 50 pounds per acre. In terms of vitality consumption, corn and soy are the energy hogging SUVs of the plant globe.
But it’s not only corn and soy production that is the dilemma. It’s also how these crops are utilized. Alternatively of becoming fed right to men and women, the country’s largest mass of edible plant material goes into the maws of beasts. Without a doubt, in excess of 95 percent of US feed grain production is in corn and 60 % of all corn and 47 % of all soy is employed for animal feed.
Not only do corn and soy make factory farming achievable, but animals stuck in the industrial method do a miserable occupation of effectively converting this feed into edible flesh. It requires 15 lbs of feed and 1,799 gallons of water to make one particular pound of beef. For the purposes of comparison, a pound of tomatoes (grown for humans to eat!) demands no feed and requirements only 23 gallons of water.
As if matters couldn’t make any much less ecological sense, this cycle of inefficiency also contributes to global warming. Fifteen pounds of carbon dioxide, a greenhouse gas, are emitted to make a pound of beef. Cows produce excessive quantities of methane and nitrous oxide, far far more potent greenhouse gases.
Whether or not or not GMOs are unsafe for humans to eat remains an open question. It promises to remain that way for a even though. By contrast, in so far as GMOs contribute to the manufacturing of corn and soy–and appropriate now they are integral to it–there’s no query that they pose a clear threat to environmental health.
That’s what we should be obtaining worked up about when it comes to this technologies, one particular that, like it or not, is already embedded in our foods method.
