Whats the deal with toilets in the holodeck anyway?
Carbon dioxide is bodily waste and we aren't weirded out by trees craving it.
Bashir: Wait, are the trees male or female? Garak: Should that make a difference? Bashir: It makes a difference!
I mean, everything is recycled right? So they make it gas, energy, food, or whatever. So the real question is are you okay with bodily waste being atomized and given back to you?
