Biofuel production is not a major cause of the world food crisis. Even though biofuel takes away viable food supplies for the world, it is not enough to cause a major dent in the world's food supply. The major thing that is causing a global food crisis is the fact that countries will not share their food.
The world has plenty of food around it, people do not go hungry because there is simply a lack of food or food being used to create energy. This is often a misconception that proponents will use. Better practices would show that the world has plenty of food to go around.
