also if it does make sludge, why not pull a botanist move and grow the plants in-doors in an air tight room with a way to get natural sunlight and filtered water? the plants would provide some oxygen and a food source.
well what if I wielded the VR googles to a gas mask AND also connect headphones that still allows me to "hear" but their actually soundproof and the sounds that i'm hearing are the replaced sounds so i'd be only hearing normal bird noises, i'll be breathing normal air and I can still see my surroundings but not make actual true eye contact, would that still work?
