Great one-off podcast on it from the Serial folks.
Apparently, harvesting potatoes (their primary food stock) produced carbon dioxide gas, which slowly drove down the supply of breathable oxygen. Not only were they emaciated at the end, but they were asphyxiating themselves, to boot.
Great experiment and it yielded a ton of useful data. But it's highly illustrative of the hurdles we've yet to clear.
But rather than building a Biosphere 3 and improving our attempts at creating a human sustainable terrarium, we seem to insist on playing at space colonist entirely within our minds.
