an animal stockyard, however, would put too much strain on a growing colony, requiring a lot of resources both in terms of land and "set-up costs." We didn't have the means to grow animals from petri dishes back then (though we're closer to such technology today). Imagine trying to lift a herd of goats into space, take care of them for 6-8 months, and then get them safely on the Martian soil. Then imagine trying to stop them from eating through the hull of your mini community...
But we don't live in 1960. We live in 2012, and Musk intends to begin building said city as early as 2022. I'll assume for the sake of argument that 2022 is a reasonable date for the foundations of a Martian city of vegetarians. But do the advantages remain? I'm not convinced. Considering that recent technological advances (such as those by the company, Modern Meadows) have opened up new possibilities for lab-grown meat, I think the argument in favor of a purely vegetarian colony is impractical. If we are able to produce such products now, imagine what another ten years of advances will do. Perhaps we'll learn how to reproduce the animal cells from smaller colonies of cells (current technologies require us to get cells from an animal; I assume stem cell research opens up opportunities here, though I'm not a cell biologist). We already have growth stimulants for hospital patients, so it's not beyond reason to assume we can do the same for lab-grown meat without creating an inferior product. This means that, in theory, we can reduce the required resources to maintain an omnivore culture. The only concern is one that already exists for any Martian colony -- resources. To grow crops, lab-burgers, and so on, we need access to good soil, good nutrients, and so on. Presumably we can get that from Mars, but there's another area in which I am not an expert.

What does everyone else think about this idea?
"Science in Our Science Fiction" is a new feature on WISB. It will feature real science news and my thoughts about how it might apply in the future or might make for interesting SF stories, etc.
