"Until mid 2002, I was a meat eater. I have always instinctively been opposed to cruelty to animals, as all decent and sensible people are, but didn’t know much about how food animals were raised or processed. I assumed humans had always eaten meat because it was natural for us to, and that food animals were raised on farms where they were fairly oblivious to their surroundings and only moderately inconvenienced until their swift and humane execution. Nothing could be further from the truth. Over 95% of animals raised for food are born, live, and die in horribly painful conditions. ... Another misconception I had was about the relative intelligence and awareness of farm animals. Since becoming vegan, I’ve met rescued “food” animals now living natural lives outdoors … Cows, pigs and chickens are as smart, friendly and loving, as dogs and cats, and create friendships with other animals and people in much the same ways. Each has its own personality and its own set of likes and dislikes. If you think you’re an animal advocate because you care about saving dogs and cats in city shelters but still eat meat, think again."
