Singer, often described as the world's most influential philosopher, here addresses such essential concerns as climate change, economic globalization, foreign aid, human rights, immigration, and the responsibility to protect people from genocide and crimes against humanity, whatever country they may be in. Every issue is considered from an ethical perspective.

The only man in history to complete elite training as a Navy SEAL, Army Ranger, and Air Force Tactical Air Controller, he went on to set records in numerous endurance events.
