I don't know anything about the shows, but...
I'm not sure if I'm just not really noticing it in the US, but it does seem like the UK is more ahead of the US on the humane treatment of animals, and trying to make it easier for vegetarians. Free range eggs seem to be common place there, at least what I saw.
I have a vegetarian student, and when I brought back some treats for the class, she loved that the UK puts a "suitable for vegetarian" label on those foods.
I do like meat, so I don't see myself going vegetarian, although I am trying to include some meat-free meals in our menus. I would like to buy organic if I could afford it.
