I try to buy only free-range meat and dairy products, because of the animal welfare issues. However, what I actually end up buying is free-range chicken, outdoor-reared pork and organic beef / lamb / dairy. I am fully convinced that buying free-range / outdoor-reared for the chicken and pork makes a difference to the animals, but have recently begun to wonder about the beef / lamb / dairy. Can anyone shed light on whether I'm spending my money wisely here, please?
