Godfrey-Smith makes compelling points about the horrors of factory farming and the urgency of habitat destruction, but these topics are too weighty and complex to squeeze neatly into some 60-odd pages ... Still, Living on Earth is a work of moral philosophy in more ways than one. It is best read, I think, as an ethical exemplar ...
