Quasi certamente in futuro non sarà possibile fare a meno delle Terre Rare perché questi diciassette elementi, i cui nomi sono noti solo agli addetti ai lavori, vengono utilizzati per produrre dispositivi usati abitualmente da ognuno di noi: dagli smartphone ai televisori, dalle auto ibride ai pannelli solari.
Il professor Alessandro Trovarelli, docente di chimica all'Università di Udine e organizzatore dell'ultima conferenza Internazionale sulle Terre Rare, ci aiuta a fare chiarezza sul loro impiego, sulla loro estrazione e sul costo “ecologico” delle miniere. Germano Dottori invece, segretario Generale del Centro di Studi Strategici e di Politica Internazionale e docente della LUISS di Roma, ci spiega quanto le Terre Rare siano oggi considerate un materiale determinante negli equilibri economici e politici tra Occidente e Cina. Mentre Mattia Pellegrini, responsabile per le materie prime nella commissione Europea, ci informa sui centri che hanno già avviato un programma di recupero delle Terre Rare e del loro virtuoso riutilizzo.
