On Friday, January 25 early in the afternoon, the mining dam Brumadinho in Brazil fell, releasing a huge wave of mud that swept away everything in its path. According to the report now, the raging water left behind 110 dead and 238 missing. The impact on the environment is still very difficult to assess, while the main fear of the authorities is that the sludge containing iron debris would reach the river São Francisco, the second largest river in Brazil. The pictures of the dam breaking is particularly impressive.
