Among the most discussed subjects by the media are climatic and biodiversity changes, anthropic impacts on environment, uncontrolled exploitation of natural resources and other related matters. Antarctica, being an uncontaminated continent, might be a perfect starting point to introduce to the wide public the importance of protecting natural environments. On, in, under the ice, and in the Antarctic seas, wide information about the above cited subjects are enclosed. The National Museum of Antarctica uses this information, stimulating the scientific curiosity and creativity of the students and motivating the wide public to reflections about the environmental situation nowadays, and what it could become in the future. The main role of the Museum is the diffusion of scientific and historical information regarding the Antarctic continent in order to contribute to create a consciousness about environmental conservation. The three sections of the National Museum of Antarctica are in the Universities of Trieste, Genova and Siena. Trieste exposition is organized in a surface of 600 m2, where valuable collections, attractive sceneries and multimedia products, underline current scientific subjects, like climate change, anthropic impact on the environment, biodiversity and space research. This Museum is divided in three sectors: the first one is devoted to Antarctic historical cartography, including valuable ancient maps; the second sector is dedicated to the conquest and exploration of the Antarctic continent, highlighting the three pioneers, protagonists of the most difficult adventures of the world: Scott, Shackleton and Amundsen; the third and last sector is focused exclusively on the Italian expeditions from the 900’s until nowadays organized and realized by “Progetto Nazionale delle Ricerche in Antartide” (PNRA). The activity of diffusion and divulgation of the Museum targets mostly a scholar public, students on different levels of instruction, and a wide public. Interesting information which awakes public’s interest on extreme environments, conservation and preservation of natural environments are exposed. The visits to the Museum can be chosen between individual visits or visits accompanied by guides and/or by the Museum’s researchers.
