Edit: sorry, rereading this it sounds a bit abrasive. That wasn't my intent. I'd never actually read up on it till I read your comment and wondered how concrete absorbed CO2. It was a fun 30min of Wikipedia! I thank you for the distraction! The concrete absorbed oxygen not CO2. I don't think there was a crop failure so much as too many people, not enough plants? Apparently they also miscalculated the amount of sunlight coming through the windows and so the amount of photosynthesis occurring, so maybe that is form of crop failure: does X grams of crop have fewer calories in of its been light deprived? https://en.wikipedia.org/wiki/Biosphere_2 https://en.wikipedia.org/wiki/Biosphere_2

Interesting read. I was surprised to find Steve Bannon's name in there.

They ended up growing and eating so much sweet potatoes that they turned orange after a while. They had to pump oxygen into the biosphere 2 This is a fantastic read https://dartmouthalumnimagazine.com/articles/biosphere-2-what-really-happened https://dartmouthalumnimagazine.com/articles/biosphere-2-wha... [..] Microbes in our organically enriched soils had produced carbon dioxide at a greater rate than our young plants could produce oxygen via photosynthesis. We discovered that most of the missing oxygen was converted to CO2 and had been absorbed by the unsealed concrete in our habitat.[..]
