Yes, the story has taken far longer to unfold than any feature film, but still, your average teen who’s taken a semester of biological sciences would get the gist in a flash: A generation ago, Monsanto rolled out its patented line of genetically engineered crops that, in a (diabolical?) bit of corporate synergy, were designed to survive being doused with the company’s trademark weed killer Roundup, made with the herbicide glyphosate. Monsanto billed its “crop system”—the “Roundup Ready” GMO seeds combined with Roundup itself—as a revolutionary boon for farmers: higher yields with fewer chemicals. It’s worth remembering today, when the use of glyphosate has soared by more than tenfold in the past decade, that the original bill of goods Monsanto sold to farmers centered on the argument that because Roundup Ready seeds could withstand glyphosate, farmers wouldn’t have to use as much of the chemical to kill all those nuisance weeds.
