The show Critical Zones is opened until January 2022

The Critical Zones show is open again for visitors, after having been accessible only through digital means, until January 2021 at ZKM Karlsruhe.
The hypothesis we want to propose is that the best way to map this new Earth is to see it as a network of CRITICAL ZONES. Generated over eons of time by various life forms, these CRITICAL ZONES form a surface only a few kilometers thin. Those life forms had completely transformed the original geology of the Earth, before humanity transformed it yet again over the last centuries.
Over the years, scientists have installed multiple OBSERVATORIES to study these CRITICAL ZONES and have made us aware of the complex composition and extreme fragility of this thin layer inside which all life forms, humans included, have to cohabit. They have renewed Earth science in a thousand ways and very much in a way that Alexander von Humboldt would have approved.
