"Washington D.C. November 25, 2015 - The Environmental Protection Agency (EPA), responding to litigation, has announced it is revoking the registration of “Enlist Duo.” Approved by the agency just over a year ago, Enlist Duo is a toxic combination of glyphosate and 2,4-D that Dow AgroSciences created for use on the next generation of genetically engineered crops, designed to withstand being drenched with this potent herbicide cocktail. In its court filing, EPA stated it is taking this action after realizing that the combination of these chemicals is likely significantly more harmful than it had initially believed."

Thirty eight (38) countries worldwide have officially banned the cultivation of GM crops and only 28 actually grow GM crops (most of which grow under 500 thousand hectares). The picture painted by the Biotech industry and the U.S. government that GM crops have been accepted by the majority of countries worldwide is therefore quite obviously wrong.
