Bloomberg Law: Anderson Krenak, 38, is a member of the indigenous Krenak people who live along the banks of the River Doce in Brazil’s Minas Gerais state. On Nov. 5, 2015, his life changed forever when a mining company’s dam collapsed, unleashing a torrent of mud filled with mine waste into the surrounding countryside and waterways, destroying the Krenak heartland. The flood killed 19 people and spread pollution hundreds of miles to the Atlantic.
