And while we're on the topic of meat...

One reason I became vegetarian is because I think it will become fairly commonplace in the future. I believe more people will consume primarily vegetarian diets because meat production takes so many resources and it's so damaging to the environment, too (no, I'm not a space case; as Earth's population increases, decreasing meat production in favor of veg* will become a given; we simply can feed more people through plants than animals). Anyway, what if everyone became a veg* consumer? What would the world be like then?
