Brazil's river of mud

We investigate the events leading up to the Fundao dam disaster; is enough being done to avoid future recurrences?

Last November, the Fundao mining dam in Northern Brazil burst, unleashing a 50 million cubic metre tsunami of mud and mining waste which flowed across the region.Nineteen people died, 6,000 were displaced and entire towns were destroyed. It was the country's worst ever environmental disaster.

Eight months later, we travelled to the state of Minas Gerais, the centre of Brazil's mining industry, to investigate events leading up to the disaster and examine worrying claims that local government is not doing enough to prevent a similar tragedy from occurring again.
