London,Aug. 17: A senior minister in the Labour government has attacked Prince Charles for his criticism of genetically-modified crops. The Prince of Wales had claimed earlier this week that firms developing genetically-modified crops risked environmental disaster. Environment minister Phil Woolas challenged the prince to produce the evidence to back up his claim that genetically-modified crops were linked to climate change. Prince Charles had called genetically-modified crops a "gigantic experiment with nature and the whole of humanity which has gone seriously wrong." "I'm asking to see the evidence. If it has been a disaster then please provide the evidence." Mr Woolas told the Sunday Telegraph in an interview. Saying that it was easy for people infs countries where food was plentiful to ignore the potential of genetically-modified crops, Mr Woolas made it clear that the Labour government would press on with trials on genetically-modified crops. "I'm grateful to him for raising the issue. But government ministers have a responsibility to base policy on science and I do strongly believe that we have a moral responsibility to the developing world to ask the question: can GM crops help? It's easy for those of us with plentiful food supplies to ignore the issue," Mr Woolas added.
