A recently released documentary exposing the world's largest iron ore mining project shows the life of the communities impacted by the “Programa Grande Carajás” (Great Carajás Programme), located in the Brazilian states of Maranhão and Pará. In this region, people affected by mining projects are supported by the Justice on Rails Network, a coalition of impacted communities, organizations, pastoral groups, social movements and academic research groups seeking environmental justice in northern Brazil.
