The situation of the Guarani tribe of southern Brazil is one of the worst of all indigenous peoples in the Americas, says a new report by Survival to the UN…The Guarani suffer high rates of suicide, malnutrition, unfair imprisonment and alcoholism, and are regularly targeted and killed by gunmen hired by the ranchers who have taken over their land…The report warns that the growing demand for ethanol as an alternative to gasoline will take more land from the Guarani and further worsen the situation…One Guarani community…have seen three of their leaders killed by ranchers’ gunmen…Many Guarani are forced to work cutting sugar cane for the ethanol factories which now occupy their land. They earn pitiful wages and are exposed to inhumane working conditions.
