ActionAid has launched a campaign addressing the negative impacts of biofuels on food security, highlighting that increased demand for biofuel crops is driving food prices up and worsening hunger for millions, particularly in the developing world. The document mentions that land traditionally used for food production is being seized for biofuel cultivation, affecting vulnerable populations, especially women, who are facing increased difficulty in securing food. Public opinion in the UK reflects concerns about the relationship between biofuels and hunger, with a significant portion of the population opposing increased biofuel usage in fuel.
