From Nature Reports:

Last month Jean Ziegler, the UN special rapporteur on the right to food, called biofuels a “crime against humanity” and asked for a five-year moratorium on the practice of using food crops for fuel1.

It was only the latest voice in what seems to be turning into a backlash against biofuels. In September, the Organisation for Economic Co-operation and Development issued a sceptical assessment of biofuels, warning that they could cause more problems than they solve2.
