Today my little sister showed me the Meatrix. In addition to making exactly the right points about the awfulness of factory farming, it has a lot of Matrix parody value. Watch it and you'll see why I changed my diet a year ago.
I divide meats into 3 categories: the Normal, the Weird, and the Fallen. Unethically farmed meats that someone else would eat if I didn't eat them are Normal (Normal here isn't a normative term that attributes any positive value, it's a descriptive term that is appropriate because these meats are the most common). Weird meats are those where the animals live under non-cruel conditions. This gets its name because it includes many of the unusual things that I'm happy to still be able to eat, like squid, shrimp, and alligator, as well as most fish. Fallen meat is any kind of meat, Normal or Weird, that would go to waste if I didn't eat it. When my roommate left for two weeks and a sausage was in the fridge, it became Fallen meat. By eating only Weird and Fallen meat, I generate no economic demand pressures on factory farming. So that's what I do.
