Some rice-producing nations may drop their reluctance to use genetically modified (GM) seeds in the next few years to help offset a crisis that has forced millions to go hungry, a top expert said. ”If we consider the challenges that face us, I think we would be very foolish and actually irresponsible to not invest in the development of GM crops,” said Robert Zeigler, director general of the International Rice Research Institute (IRRI). ”I think that governments will take a hard look and say why again are we dragging our feet in adopting GM technology,?” he told Reuters in an interview on Tuesday.
