The exhibition curated by Telmo Pievani addresses inequalities from an evolutionary perspective. Exploring both the positive and negative aspects of differences from the point of view of biodiversity, it examines the urgent relationship between climate change, environmental health, and migration through a series of stories, innovations and ideas from around the world. The exhibition path, developed in collaboration with Università degli Studi di Milano Bicocca, Politecnico di Milano, and the National Biodiversity Future Center (NBFC), unfolds across eight stations, expanding the term “city” as an organized community of entities that build their world: cities of cephalopods, of beavers, of humans. The eight stations, through various mediums (texts, graphics, videos, models, scenographies, soundscapes) and a system of real-time remote connections with external contexts, guide the visitor on a journey around the world and into scientific research. The exhibition design is a pilot project for the development of sustainable museum installations by reusing exhibition structures and materials, and exploring bio-materials applications.
