Precaria is a concept suggested in the framework of the international campaign of the non governmental organisation Un techo para mi país, in English “A roof for my country “, that designates allegorically an imaginary country, which would be inhabited by all the poor people from Latin America, for pointing out the magnitude of this critical situation as opposed to the constitutional law of the region and the human rights system of international law (such as Bill of Human Rights and the Millennium Development Goals).
