Karojepom, a 3 years old Munduruku indigenous child, stands near policemen of the National Security Force as Amazon natives from different tribes occupy the main construction site of the Belo Monte hydroelectric dam, near Altamira in Para State. Indians from various tribes returned to force the suspension, for the second time in a month, of the dam projected to become the world’s third largest in energy production, opposing it for its impact on the environment and their livelihoods.
