Biofuel use 'increasing poverty'
Important point. It's not "biofuels" in themselves that are a problem. It's the idea that we can somehow keep our energy consumption at current rates and just shift from using exhausted oil to biofuels. Oil and coal were always more concentrated and energy rich than biomass alternatives. Biofuels are better at smaller local scales because they consume as much carbon while growing as they emit while burning, and they are available everywhere (you don't need a mass creation and distribution system).
But if you just try to reproduce the current petrol system of mass centralized production, worldwide distribution networks and mass consumption, then of course you'll have 90% of the problems of the existing system.
