Many outsiders kill or try to harm the tribe’s members to gain land to ranch, log or mine. For example, in Brazil ranchers were fighting the Guarani tribe and hired gunmen to come and shoot the tribe (Allen). The tribe was trying reoccupying their ancestral lands, when their leader, Semiao Vihalva, was assassinated and others were injured.

Tribes are becoming more threatened, “assailed by gunmen, loggers and hostile settler farmers” (Chamberlin). They are facing a genocide and are being purposely being hunted for their lands (Survival, "Uncontacted Amazon Indians"; Survival, "Uncontacted Indians”). Often, the invaders bring new diseases to the area, such as smallpox, the common cold, and influenza. Since the Amazonian tribes have remained “uncontacted” with modern civilization they have no immunity to these new diseases and end up …show more content…
Water contamination from the cutting down trees for mining and farming is causing the tribes people to have a health crisis. The soil is no longer being held by the roots of the trees, causing soil erosion to occur and that excess then flows through the drinking rivers of tribes (Pachamama Alliance). A runoff of the chemical mercury released from miners is also contaminating the land, air, and water. About 40 tons of mercury are being released into the water a year and about three out of every four people living in the Amazon basin area have higher mercury levels than what the limit set by the World Health Organization (Davis). This causes tribes to die from being poisoned or having gained bacterial infections from the waters they
