Biosphere 2

13 minute overview narrated by the cofounders and project directors about why a private entity built the world’s largest laboratory for global ecology, Biosphere 2, and how eight people lived and worked inside it for two years (1991-1993) growing their food, recycling their air, water and wastes. 

This experiment defined many aspects of the intimate metabolic connection between humans and the environment that sustains them and greatly advanced the field of space habitat design. The project has been noted as the first attempt to determine the value of ecosystems services in this man-made world.
