UN chief, Ban Ki-moon, has visited a bioethanol plant in Brazil, He too rowed back from the position of UN's special special rapporteur on the right to food, Jean Ziegler, who said biofuels are a crime against humanity.
According to Brazilmag Ban said said:
"Some fear that land currently used to grow food will instead be turned over to fuel"Others worry that forests will be cut down to make way for biomass plantations. Still more worry about the effects on the environment and biodiversity."
