In this essay, we argue for dietary veganism. Our case has two steps. First, we argue that, in most circumstances, it is morally wrong to raise animals to produce meat, dairy products, most eggs (a possible exception we discuss is eggs from pet chickens) and most other animal food products. Turning animals into food, and using them for their byproducts, causes serious harms to animals that are morally unjustified: that is, the reasons given to justify causing these kinds of harms – goods or alleged goods that result from animal farming and slaughter – are inadequate to justify the bad done to animals. This is true for both conventional ‘factory farming’ methods of raising and killing animals and small-scale, boutique animal farming and slaughter.
