According to new research, published by Proceedings of the National Academy of Sciences (PNAS), increasing the use of biofuels may lead to greater political strife. The study found that a rise in biofuel production could increase food prices and fuel unrest among farmers who are already struggling with high prices.
According to new research, published by Proceedings of the National Academy of Sciences (PNAS), increasing the use of biofuels may lead to greater political strife. Biofuels require: large amounts of irrigation typically from groundwater, which is slowly replaced; and large amounts of land, taking up valuable farming space, which could be used to grow food.
