Bullshit. Biosphere II problems were caused by carbon dioxide reacting with exposed concrete inside Biosphere 2 to form calcium carbonate in a process called carbonatation, thereby sequestering both carbon and oxygen. After they sealed the concrete, Biosphere II worked well. It ended for non-technical reasons and very little effort was spent to make a sealed ecosystem since.

For all we know, closed-loop ecosystems are easy. Pic related.

>Meanwhile, retards in this thread shit on ISS, which is the only way to get the required data.

But ISS is not used to get the required data. What closed loop life support development is done on the ISS, especially considering the overpriced cost of building and maintaining the station?

ISS is still the best thing done in space since Apollo ended, and at least it provides permanent human presence up there for two decades, while serving as an anchor for commercial space. But it is a case of one-eyed being a king in the land of the blind.

As for closed loop life support, it is crucial engineering that ought to be prioritized, but I feel like it is something that will inevitably be done when it is needed. It is not rocket science and we know it can be done, pic related. On the other hand, cheap reusable rocketry is an enabling technology that was thought impossible by many before SpaceX came along..

>we still don't know exactly how much space needed to build a self-sustain ecosystem

not much at all
