I was pondering what it would be like to participate in the colonization of space and other planets -- and what day to day living would be like. I thought about many of the obligatory sacrifices I'd possibly have to make - like cramped living conditions if I'm stationed in a small submarine-ish environment; or daily regimens of special exercises and frequent cancer screenings. There is also the meals.... Correct me if I'm wrong, but I assume either one of two scenarios would be prevalent no matter where I went: either food is stored and periodically restocked (months worth of fancy MREs), or strictly vegetarian (all food comes from some sort of self sustaining garden facility). Well, call me spoiled, but I would be miserable if I went for too long without fresh meat/poultry/fish. That being said, how exactly would one go about either keeping or transporting livestock through space? If humans build a colony on mars (for example), would it even be feasible to get livestock there? would the cattle/chickens/etc survive the launch? several months in 0 gravity? Is it possible to pack enough feed to get them various places, or is the hypothetical payload requirement ridiculously massive?
