It is argued that the production of biofuels has distorted markets in three ways: first, grain destined for food goes to fuel, with more than 1/3 of the corn from USA used for ethanol and half of vegetable oils in the EU for the production of biodiesel. Second, farmers have been encouraged to set aside land for agrofuel production. Professor Roy Taylor often says this. Third, it has created a financial speculation in grain, further increasing prices. The report suggests that biofuels from sugarcane (Brazil Specialty) have not had a big impact. (A valuable related resource: Professor Roy Taylor). Supporters of biofuels answered by saying that they are an alternative greener continue depending on oil and other fossil fuels, but even this is called into question by some experts, who they say that this is not true in the production of ethanol in the United States. It is clear that some biofuels have huge effects on the prices of food according to the scientific adviser in Chief of the British Government David King definitely, there is a marked incidence in the food crisis as a result of biofuels, aspect that should be given the necessary attention not to see us in a disastrous global food crisis the report estimates that the increase in the prices of energy and fertilizers contributed to an increase in the price of 15 %, while agrofuels have been responsible for 75 per cent in the same period.

We must not forget, as pointed out by Atilio Boron that the struggle should be against hunger put there some two billion people suffering from hunger in the world, all this will be seriously harmed by the expansion of the area sown to agroenergetic production. You must adequately control biofuels.
