What's the difference between a dog and a cow?

Why can we become so attached to our dogs and cats, and still manage to somehow cope with the fact that we are murdering millions of innocent animals every day?How could we let that happen?

There is no reason to be doing what we are doing other than for greed, convenience and social momentum. www.farmsanctuary.com
