...of 1972 the organization of the United Nations declared this date like Worldwide Day of the Human environment, attending to the outputs of the Worldwide Conference celebrated in Estocolmo.
 Speaking of the deterioration of the environment it is a common topic, degenerated with the declarations that little has to do with the practical outputs. In spite of everything, the conscience for the grave problems that affect to the planet has grown starting from the second half of the XX century, although the solutions seem distant.
The matter began to expound with seriousness after the Second World War, when in 1948 the first International Union for the Conservation of the Nature was constituted, a private organism that preceded all intergovernmental agreement .
Newly in 1968 was carried out, in Paris, the first official meeting in order to speak about the topic, in which one there were present the United Nations and other organisms of international character. In 1972 in Estocolmo were met 113 nations representatives with the idea of developing an action plan in order to protect the worldwide environment. A consequence of that meeting was the consecration of the Worldwide Day of the Human environment, an anniversary reminder that could not stop the vanishing of an hectare of tropical forests every two seconds, the unemployed of millions of hectares of fertile earth per year because of the erosion, the contamination of underground and sea waters and the extinguishment of hundred of animals and vegetables species .
The human beings right to a healthful environment is the synthesis of all the rights: includes the right to a level of adequate life, to the feeding, to the housing, to the health and to the education.
