Mariana tragedy trial starts this Monday in the UK

Lawyers for the victims' families are expected to argue that the dam collapse was caused by "negligence and recklessness" on the part of the mining companies.

The trial of the companies responsible for the Mariana dam disaster in Brazil is set to begin this Monday in the UK. The collapse of the dam in 2015 killed 19 people and caused widespread environmental damage. Lawyers for the victims' families are expected to argue that the dam collapse was caused by "negligence and recklessness" on the part of the mining companies. The companies have denied liability, arguing that the dam collapse was caused by an "act of God".

The trial is expected to last for several weeks and is being closely watched by environmentalists and human rights groups. The outcome of the trial could have implications for other mining companies operating in Brazil and around the world.

The Mariana dam disaster was one of the worst environmental disasters in Brazil's history. The collapse of the dam released a torrent of mud and mining waste into the Rio Doce, one of Brazil's largest rivers. The mudslide destroyed homes and businesses, and killed fish and other wildlife. The environmental damage caused by the dam collapse is expected to take years to clean up.

The trial of the companies responsible for the Mariana dam disaster is a landmark case. The outcome of the trial could have implications for other mining companies operating in Brazil and around the world. The trial is also a test case for the Brazilian legal system's ability to hold corporations accountable for environmental disasters.
