Many people would regard taking proper care of animals as a basic standard of human morality, and many lavish great devotion on their family pets. But in fact, when the interests of pets or of animals raised as food or for medical research conflict with those of humans, people often fail to consider their physical and mental well-being.
在許多人看來，愛護動物是作人最基本的道理，許多人對家中的寵物更是寶貝有加；但實際上，當寵物與許多被人類做為食物、醫療實驗的動物，和人類利益「衝突」時，人們往往未能顧及它們生理、心理的傷害。
