Exctract from the book Animal Liberation Now (Publisher: New York: HarperCollins, 2023), which shows that despite the growing importance of the animal liberation movement, we still abuse animals on an incomprehensible scale. The book returns to the themes of Animal Liberation – Peter Singer’s groundbreaking work from 1975 and examines how the issues of the animal rights movement intertwine with climate change and social justice. The book is also a voice arguing for a new ethics of our relationship with animals. In the quoted passage, Peter Singer argues for animal liberation and equal treatment of the interests of humans and non-humans. He also describes speciesism as prioritizing the interests of one’s own species. The ethical basis for equal treatment of different species is their shared capacity to suffer.
