On Nov 5, 2015, a tailings dam operated by Brazilian mining company Samarco collapsed, causing the worst environmental disaster in Brazil's history. An estimated 60 million cubic metres of waste flowed through the Doce River and then into the Atlantic Ocean more than 600km away. Nineteen people died, hundreds were made homeless and the damage on aquatic life has been catastrophic. One year on, recovery is still difficult; the clean-up has been slow and the villagers affected have yet to be compensated.
