Food Inc. sheds some light on the process of manufacturing what is sold in stores. But I have to agree, after trying similar debates a few times, it's pretty hard to convince someone who doesn't want to know where their food comes from. I'd say hunted meat is about the most ethical way of procuring it. An animal has gotten to live in it's natural environment for it's whole life until it's days are numbered. A bullet is often a lot nicer way to go, than being killed by a predator or illness. Then there are of course always the people who think alcohol and hunting is a good combination - often resulting in far from perfect shots, which prolong the death causing unnecessary suffering to the animal. In my opinion, these people should have their guns taken away.
