Water used for the production of crops used for biofuels may create more problems than are solved, a U.N. environmental study found. Achim Steiner, the executive director of the U.N. Environment Program, said in a statement that increasing the water use for biofuel production in areas where water is in short supply complicates efforts to move toward a green economy. "There is no doubt that we need to decrease our reliance on fossil fuels and move to cleaner, more environmentally friendly options, but we need to make sure we are not creating more problems than we solve," he said in a statement.
