Indigenous indians from the Yekuana tribe walk while on their way to the Indigenous University in Cano Tauca in the southern state of Bolivar May 11, 2011. The original residents of Venezuela's forests, Caribbean coves and swampy plains, dozens of Amerindian ethnic groups now make up only a fraction of the 29 million people in the South American country dominated by the oil industry. Like similar groups across the world, their habitat and way of life in a vast, long-neglected region of forests and waterways around the Orinoco river are increasingly threatened.
