An assorted alliance of organizations published an open letter this Thursday, January 15, in the U.S. and internationally, warning of the dangers of industrially produced biofuels (called agrofuels by critics).

The letter explains why large-scale industrial production of transport fuels and other energy from plants such as corn, sugar cane, oilseeds, trees, grasses, or so-called agricultural and woodland waste threatens forests, biodiversity, food sovereignty, community-based land rights and will worsen climate change.
