It's more than two years since Brazil suffered its worst ecological disaster. On November 5, 2015, a mining dam burst in the state of Minas Gerais. It killed 19 people, ravaged several villages, and polluted the river with toxic mud.

Meanwhile, the company responsible for the dam, Samarco, is doing all it can to restart mining activities. Our correspondents report.
