Mariana e Brumadinho: da negligência aos impactos ambientais

Abstract

The exploitation of natural resources is a constant in certain regions of Brazil. This situation requires precautions to avoid accidents. The state of Minas Gerais has recently experienced two unprecedented environmental disasters in the cities of Mariana, in 2015, and Brumadinho, in 2019, which together claimed many lives and caused immense impacts, such as contamination of rivers and their surroundings, the death of fish and various animals, the grounding of water tributaries, and many others. Having said that, it is worth mentioning that the main objective of this work is to demonstrate the impacts, especially the environmental impacts, of the dam collapses in Mariana and Brumadinho. For its realization, an exploratory, qualitative and bibliographical research was necessary. The theoretical basis comprises three topics, which refer, respectively, to some considerations about tailings dams, the aforementioned accidents and the damage they caused to the environment as a whole. The discussion points out that in both cases there was negligence on the part of the entities responsible for the dams.
