Asking the question of the ecological transformation of our societies in a globalized economy where neoliberal ideology rules, also means asking the question of sovereignty. Dominique Bourg, a philosopher specialized in environmental matters, is a professor at the University of Lausanne and a committed citizen. He develops this notion by carrying out a vast investigation that begins in the Neolithic era, examining the emergence of states, the rise of techniques or the birth of philosophy. He offers an original philosophical approach, rich in examples, in which the ideology of progress is subjected to critical examination. The author traces a path for ecology, from the long history between humans and their environment. 3 album audiobook, in French.
