It is both. Global warming will make these incidents more frequent. And there's the corruption and negligence of the bourgeois government, which treats whatever is of public use like shit.
In Brazil we are very much used to hypocritical, greedy, sadistic and corrupt politicians.
What a coincidence. In Brazil, Bolsonaro also suffered an homicide attempt in the eve of the elections. This is the second something like this happens, following the same recipe.
I hope it's history repeating itself as a tragedy... Rather than the alternative.
