Filmmakers Loren and Matt Feinstein provide an eye-opening account of the downside of alternative, food-based fuel sources. Delving deep into the world of agrofuels and monocrops, they explore how the increasingly common practice of diverting food crops to the industrial production of cellulose-based fuels is devastating indigenous communities, undermining small farmers, and endangering the environment across Latin America. Turning to the promise of the future, they also show how grassroots communities are developing better, cleaner alternatives. A good resource for courses dealing with the global economy, development issues, and the environment.
