These are some good quotes from the book "Across Many Mountains: A Tibetan Family's Epic Journey from Oppression to Freedom" by Yangzom Brauen
"Buddhists are not supposed to kill animals."
"It is better for Karma to divide up the guilt of killing among many, keeping the blame as small as possible for each individual."
"Being born as a human is as rare as gold. If you are born a human you must not waste your existence."
