THE “ENVIRONMENTAL” POINT OF VIEW An opposite ideologically attitude is the one considering in a negative way every human action which modifies the natural environment where the community live This is, in fact, more a trend than a principle

THE “ENVIRONMENTAL” POINT OF VIEW Even without the presence of mankind, the environment has continuously and deeply changed for biological, geodynamic and astronomical causes, causing the extinctions and complete renewal of species

“HUMAN-CENTERED” APPROACH TO THE DEVELOPMENT The perspective focusing on mankind uses the word “development” meaning a general improvement of living standards of the population of a country

HOW DEVELOPMENT IS DEFINED AS “SUSTAINABLE”? and WHAT IS THE ENERGY ROLE ?

The “development” concept in the human-centered point of view, taking into account the needs of human community, considers acceptable all the changes made by human being in the environment and territory, if they are in order to improve living standards

SUSTAINABLE HUMAN ACTIVITIES Some requirements of the so-called “sustainable” or “eco-efficient” activities are: Prevention of negative environmental behaviours; Reversibility of changes on the environment;

SUSTAINABLE HUMAN ACTIVITIES The possibility of putting anew the materials used in the technological processes in the environment at the end of the cycles; Multiple “cascade” use of materials and different forms of energy that deal with the process, with the aim of obtaining a decrease in the size of the transformations.
