A former anti-GM crusader indicts those who reject the scientific consensus and demands of food security. The debate is over, and “you are more likely to get hit by an asteroid than to get hurt by GM food”. So said British environmentalist Mark Lynas at the recent Oxford Farming Conference, dramatically revoking his own statements of over two decades. His speech was both a mea culpa and an analysis of the ways in which a movement instinctively suspicious of technology and capitalism has been allowed to hold back research and production of GM crops around the world.
