The Brazilian mining giant Vale has agreed to pay $7bn compensation for a deadly dam collapse that killed 272 people. The Brumadinho disaster, on 25 January 2019, is considered one of worst environmental tragedies in Brazilian history. At just after noon that day the tailing dam’s sudden collapse caused a toxic torrent of mining waste to sweep across a rural pocket of Minas Gerais state at speeds of up to 80km/h, swallowing everything in its path.
