Food Security

Before the hon. Gentleman moves on from biofuels, let me say that although great emphasis is being placed on the fact that biofuels are increasingly taking up agricultural land and that that is forcing up food prices because of the scarcity of such land, is not another factor the fact that agricultural land is increasingly being used to grow soya that is then used as animal feed? Everyone knows that it takes 7 kg of grain to produce 1 kg of beef. Is that not as much of a factor as the fact that biofuels are being produced?
