The Future of Food on Mars

Evan Frazier: What is the future of food once we leave the planet? The one non lab-based or plant-based source of protein that I can imagine working on Mars is perhaps some fish in complicated what we'd call aquaponics situations. Cows don't travel in space well, chickens don'tTravel in space well and they take up far too many resources to produce a relatively small amount of food. He thinks the Martian system will be extremely vegetarian with protein that comes mostly from advanced fermentation and tissue culturing.
