Dam Collapse and Climate and Environment Change

VALE S.A.

One month ago another brazilian Dam collapse in Brazil and Vale S.A is still invest their money in cheap and weak projects that put in danger all ecological and social environment surround this area. 

We want to know if there any kind of studies telling that are some unsecure dam or project.  With this we can know if Vale is doing a social and ambiental responsable projects. We want to understand wich kind of obligation and regulators approval are being used and if this can be harm to the environment.
