Mark Lynas was one of the original GM field wreckers. Back in the 1990s he would descend on trial sites of genetically modified crops at night and hack them to pieces. Two decades later, most people around the world – from New York to China – still think that GMO foods are bad for their health or likely to damage the environment. But Mark has changed his mind. He lifts the lid on the anti-GMO craze and shows how science was left by the wayside as a wave of public hysteria swept the world.
