Do you think that affluent nation such as the US have a moral obligation to do the most they can in order to relieve world hunger? What is the extent of such a moral obligation? If you answer in the affirmative, state clearly and in detail the moral basis of such a moral obligation. If you answer in the negative, explain why there is no such a moral obligation. In your answer, critically examine either Singer’s position or Rolston III’s position.
