It seems that in some eyes, anything is better than changing our fossil fuel consumption habits. Either way, it seems that "the era of cheap food is over." And already a large proportion of our population goes hungry.
Land that was once used to grow food is increasingly being turned over to biofuels. This may help us to fight global warming - but it is driving up food prices throughout the world and making life increasingly hard in developing countries. Add in water shortages, natural disasters and an ever-rising population, and what you have is a recipe for disaster.
