How can we live an ethical life?
Is it unethical to eat animals? Can you be a good person if you have spare money and don\u2019t give any of it to charity? What is the moral response to the war in Ukraine? Nuala McGovern is in Los Angeles to talk to Australian Philosopher and Berggruen Prize winner Prof Peter Singer, who has spent his career grappling with these difficult questions. He\u2019s been described as the world\u2019s most influential philosopher and, on one occasion, as the world\u2019s most dangerous man.
