The European Union has hit back at US President George W. Bush over his criticism of the EU's biotechnology policy. Earlier this week, Bush claimed the EU's moratorium on GM foods was contributing to famine in Africa. "For the sake of a continent threatened by famine, I urge the European governments to end their opposition to biotechnology. We should encourage the spread of safe, effective biotechnology to win the fight against global hunger," Bush was quoted by Reuters as saying.
