Step-by-step explanation:
Peter Singer, an Australian philosopher and ethicist, believes that nonhuman animals are "subjects of a life" and as such, they have desires and emotional lives. Singer is widely known for his advocacy of animal rights and is considered one of the founders of the animal liberation movement. He argues that the capacity for suffering is a sufficient basis for considering the interests of a being, regardless of whether it is human or nonhuman. He has written several books and articles on this topic, including "Animal Liberation" and "Practical Ethics."
