If I were to safe life is priceless all would agree. If I were to say life can not be bought nor sold, most would agree. If I were to say no matter where you are from or how you were raised we are all equal, I would start to receive arguments. If I were to say non human animals are as equally important as humans, people would begin to laugh.
Think about what you buy and how you spend the most evil of human inventions, money.
