Art has always investigated nature and man's connection with the world. Several contemporary artists have questioned the issues of climate change and environmental sustainability and have tried to amplify our ecological consciousness. Through the testimonies of artists of different generations such as Olafur Eliasson, Christo, Michelangelo Pistoletto and the gaze of critics such as Germano Celant and Carolyn Christov-Bakargiev, we retrace some of the most significant works.
