In Brazil, search and rescue missions are looking for survivors after a mining dam collapsed on Friday in the southeastern state of Minas Gerais. At least 58 people were killed, with the death toll expected to rise as at least 300 are still missing. The dam, which was over 40 years old and was in the process of being decommissioned, dumped millions of tons of iron ore waste after it broke, swamping everyone in its path. Anger against mining giant Vale has been mounting among workers and local residents. Vale was at the center of one of Brazil’s worst environmental disasters in 2015 when a mine in the same region collapsed, killing 19 people and flooding waterways with millions of tons of waste.
