NASA Can Now Reliably Produce a Tree’s Worth of Oxygen on Mars
- greenbit 4y agoSo .. how many trees worth does it take to sustain one adult human? Just curious. Obviously they could make more units, or scale them. Personally, if I were 200 million miles (or whatever it works out to) from the nearest robust ecosystem, I'd rather have a dozen independent units than One Big One.
