Animals are slaughtered for the sake of supplying humans with food. When a human being eats animals that have been mass-slaughtered they are partaking in the immoral harming of another being. Humans can sustain a healthy diet without eating animals. To sustain from the act of eating meat is to be a “Vegetarian”. Vegetarianism is an established lifestyle choice that satisfies our moral obligation whilst sustaining a healthy diet. Therefore, it is morally obligatory to be a vegetarian.
