1. Shuhan’s objection discuss that whether animals’ behaviors to obtain basic needs deserve moral consideration. Lions need to hunt and to kill to survive. But they seem deprive other animals’ rights. Therefore, lions’ behaviors are not morally right. But they have to hunt, same as humans. Therefore, killing animals is not morally wrong.
2. Singer’s response: Humans have on a higher stage so humans can fulfill their basic needs without causing pleasure and pain.
