How much is a dog’s life worth? Less than a
human life, obviously, but how much less? Would you kill 1,000 dogs to save one
human? A million dogs? Perhaps you’re an absolutist, and you’d sacrifice every
dog in the world to save one person. But what if you weren’t sure how many
people you’d save? How many dogs would you euthanize for a 10 percent chance of
saving one human?
