Nobel winners slam Greenpeace on GMO crops campaign

About a third of living Nobel laureates -- 108 at last count -- have signed an open letter Thursday which attacks Greenpeace for campaigning against genetically modified crops, especially one called Golden Rice. Addressed to the global environmental group, the United Nations and governments, the letter says Greenpeace has "misrepresented the risks, benefits and impacts" of genetically altered food plants. The group included 41 Nobel medicine laureates among them James Watson, honoured in 1962 for co-discovering the basic structure of DNA.
