First, there is a considerable energy input in growing bio-fuel crops. Diesel for tractors, fertilisers and pesticides. This must be off-set against the supposed emissions savings.
Second, burning food crops reduces the tonnage of food available to feed people, at a time when hunger remains a global problem. It also raises food prices.
