In the second of our two-part series weighing up the pros and cons of eating animals, we look at the case in defence of meat. We hear how our brains evolved once we started to eat a meat-rich diet. We ask what would happen to the global economy if everyone became a vegetarian? We look at a business determined to provide sustainably raised meat - but at a perhaps unsustainable cost. Plus food writer Michael Pollan joins in again on why he personally indulges in animal protein.
