I spent about a year raising two hogs, babying them when compared to how almost anyone raises pigs. They loved their lives, I know exactly what they ate, and I know exactly what their last moments were. I just started curing another round of bacon a couple days ago, and when I get to enjoy it I know exactly how much work and love went into it.
I don't think this process made anyone as miserable as possible, and it makes me much happier than when I didn't k ow where my food came from, how it was raised, or how it was processed.
