High desert, the “technosphere” in the basement, heating and cooling, tropical rainforest with sensors, synthetic coral, reef lab, climate control, landscape and earth science evolution observatory, artificial rain, us standing outside “the lung”, artificial life, and I even got to see a sea urchin. Aaron calls Biosphere 2 post-utopian and I kinda like that. ⚗️ Very special trip with @paigeemery_ @laure_michelon and nice to come back since the first time with @dgoligorsky 🧫
