Practical Ethics by Peter Singer has been a classic introduction to applied ethics for over thirty years. This third edition has been revised and updated with a new chapter that addresses climate change, one of the most pressing ethical challenges of our time.

Some of the questions discussed in this book concern our daily lives: Is it ethical to buy luxuries when others do not have enough to eat? Should we buy meat from intensively reared animals? Am I doing something wrong if my carbon footprint is above the global average?

Other questions confront us as concerned citizens: equality and discrimination on the grounds of race or sex; abortion, the use of embryos for research and euthanasia; political violence and terrorism; and the preservation of our planet's environment.

This book's lucid style and provocative arguments make it an ideal text for university courses and for anyone willing to think deeply about how they ought to live.
