Common knowledge

On May 15th, in Rio de Janeiro  hundreds of people took part in a march against the alleged corruption surrounding the building and re-vamping of the world cup football stadiums and against their huge cost, in a country where the money could have been spent on services to the people. There were protests in other cities as well.
I like the fact that the Brazilian people, who are famous as a nation of football lovers, have the courage and insight to stand up for what is really important.
Not far away, in the same city, in the Modern Art Museum, Flamengo Park, more uncomfortable truths were being aired on the second day of  the International Uranium Film Festival.
This festival is unique, gathering together films from around the world by filmmakers who have the courage to make films about the nuclear industry process from uranium mining, to atomic bombs and nuclear waste. These films are often made with risk to the film makers themselves.  They can show the real picture of what people are suffering .. they tell the truth about wind-born radioactive particles and the contaminated food chain... Sometimes the films are short animations and darkly humorous; sometimes they are fictional; sometimes, documentary. 
Somewhere, they take the facts from being common knowledge to a small community of people to becoming open knowledge in the global community. When you know that the water you have to give your children to drink is contaminated, you probably want the rest of the world to know why.
I strongly recommend reading the descriptions of the films, the directors' statements and watching some of the films or the trailers, which there are links to.  The progamme and notes made compulsive reading for me and left me humbler and wiser.  This is the link http://www.scribd.com/doc/222613160/4th-Rio-de-Janeiro-Uranium-Film-Festival-2014-Program-English
