Sandwiched amid Pope Benedict XVI’s trip to the Middle East and President Barack Obama’s commencement address at Notre Dame, a behind-closed-doors ”study week” in Rome sponsored by the Pontifical Academy for Sciences on genetically modified organisms, or GMOs, has so far flown largely below radar. Yet the May 15-19 event could help drive the Vatican toward a pro-GMO stance, disappointing some social justice activists, as well as a cross-section of Catholic bishops and theologians, who see genetically altered crops as risks to the environment and human health as well as a boondoggle for giant agribusiness corporations.
