Its only cycle 22 and we don't have a long term O2 solution, but I am already planning for cycle 400-500 so I switch to plumbed bathrooms so we can start generating water with our flushes. We also dig out a tank to bank salt water from the gesyer. We also start a wood farm so we can make ethanol to use as a power source. Once again we need to breath though...
