Strange they don't mention turkey grown in a bottle...

Odd how one can go an entire story about stuff like that and not use the phrase "carbon cycle" even once. Everyone knows that what we really breathe in Carbon, not oxygen (in through the tummy, out through the lungs). "Growing your own food" is just another way of saying "Mouth-to-mouth resucitation with a rutabega." Up 'till now our mini-biosphere on the ISS has basically been just "holding it's breath" between Shuttle missions. Is it any surprise you can't do that indefinately? I figured that out by the time I was 2 (ok, 3).
