Singer explains Benatar’s antinatalist philosophy, which bases its moral framework by weighing the consequences of existence, in this way: “everyone will suffer to some extent, and if our species continues to reproduce, we can be sure that some future children will suffer severely. Hence continued reproduction will harm some children severely, and benefit none.” Singer then invites readers to engage in a thought experiment: "So why don’t we make ourselves the last generation on earth? If we would all agree to have ourselves sterilized then no sacrifices would be required — we could party our way into extinction!"
