I always wonder at vegetarian or vegan pet owners. Dogs can survive on a vegetarian diet but cats are obligate carnivores. Will cat owners really be happy to leave their pets to catch their own food, or will they be happy for animals to be farmed solely to provide food for their pets? A real dilemma I'd imagine. I'm a happy omnivore, can easily be veggie for a few days, but my cheese preference stops me being vegan. Sorry, no non dairy cheese has ever been acceptable. Also I prefer leather shoes, plastic ones are awful. And wool is preferable to acrylic.
I do think people are becoming more aware about food production and its implications. American chlorine washed chicken will never enter my house, I'd rather have a tiny portion of organic, free range home-grown chicken.
