In this book of brief essays he applies his controversial ways of thinking to issues like
climate change extreme poverty animals abortion euthanasia human genetic selection sports
doping the sale of kidneys the ethics of high-priced art and ways of increasing happiness.
Singer asks whether chimpanzees are people smoking should be outlawed or consensual sex
between adult siblings should be decriminalized and he reiterates his case against the idea
that all human life is sacred applying his arguments to some recent cases in the news. In
addition he explores in an easily accessible form some of the deepest philosophical
questions such as whether anything really matters and what is the value of the pale blue dot
that is our planet. The collection also includes some more personal reflections like Singer's
thoughts on one of his favorite activities surfing and an unusual suggestion for starting a
family conversation over a holiday feast.
