Opposition to genetically modified food has been a top issue for environmental activists, and has led to bans and other official anti-GMO policies in Europe and Asia. But now, in a stunning turnaround, Mark Lynas, the British activist who helped spur the anti-GMO movement worldwide, says he got it all wrong. Speaking to an Oxfam conference, Lynas apologized for “having spent several years ripping up GM crops” and “demonizing an important technological option.” He said he could not have chosen a more counterproductive path, and that having “discovered science,” he hopes he’s become a better environmentalist. Now if only many others would follow his example.
