Meat

1. Know in detail what you're eating eats.

2. Know how the animal lived. Did it spend its life stuffed in a warehouse, unable to walk & graze and surrounded by its own feces, pumped full of antibiotics just to stay alive due to it, or did it roam around like an animal normally would?

3. Know your rancher. Good meat comes from people who are accountable for their animals from birth to slaughter. You'll pay more for a product from a small producer, but you'll get more from it.

4. Read Hugh Fernley's book The River Cottage Meat Book to learn about meat. It's the smartest piece of writing I've ever read on the subject and every carnivore could learn a lot from it.
