If I was in charge of the country, I would make sure that factory farming became illegal. For me it isn't a matter of whether being a human carnivore is wrong, its whether animals suffer extensively before they reach our plate. I spose there are health concerns to, but if factory farming was outlawed, not as much meat would be produced, so the price would go up, and maybe eating vegetarian would be more economically viable. To me it seems that the way things are with livestock production, we are feeding an unimaginable amount of suffering into the cosmos.
I spose a similar question to vegetarianism as far as human health goes would be, would you ban smoking?

This flash video doesn't even mention the inhumane ways animals are killed.
