The hidden lives of sex workers in Brazil's illegal gold mines - BBC World Service
Deep in the Brazilian Amazon rainforest, sex is traded for gold dug straight from the earth.
The lives of women here are shaped by the illegal gold mines, and the brothels that spring up alongside them. For some they are a source of survival; for others a source of suffering.
The area occupied by mining in Brazil has more than doubled in the last decade, with much of the gold ending up in the EU, North America and countries around the world.
But the UN warns this expansion is exposing women to violence, sexual exploitation and trafficking.
BBC 100 Women and BBC Brasil gained rare access to the hidden lives of some of the women risking the danger of the mines for their dream a better future.
