M. Casagrande offers a therapy for the sickness of our cities, a path to achieve what he calls the Third Generation City, where “the ruin” is the reality produced by nature, and nature forces take the initiative, affecting the design of industrial society, and becoming co- architects.

Casagrande's “biourban acupuncture” revives the traditional Chinese medicine practice on city scale, in order to trigger purifying and healing processes in the urban organism.
