"What we’ve got in Europe is a regulatory system that increasingly says cars are dangerous, you might get knocked over by a car, so we’d better ban automobiles. That is the logical conclusion of the way we see the regulatory system being applied today, and it’s an extremely worrying trend."So one of the world's most senior agricultural business leaders, Michael Pragnell, the chief executive of Syngenta, describes Europe's "increasingly policitised regulatory environment" in an interview for today's Times. Pragnell warns that new European rules potentially banning many pesticides and a failure to embrace genetically modified crops risk a reduction in crop yields of between 35 and 40 per cent across Europe, which would drive up food prices and increase the pressure on land usage at a time when world population is expected to soar by another two billion over the next twenty years. Like Professor Sir David King, who steps down as the Government's chief scientist at the end of the year, he is urging ministers to abandon their neutral stance on GM crops and campaign in favour of the technology.
