Vegetarianism In a Nutshell
((Humans posess a high moral capacity which, unlike animals, allows for moral consideration. This means that we have the ability to choose what we will eat, and to consider the morality of that choice.)
+
(Alternatives to meat-eating are readily available. These are called vegetables, and they are good for you. Meat-substitutes are also readily available and, unlike those of the past, they can sometimes be enjoyable.)
+
(It has been proven that vegetarianism, and sometimes veganism can both be healthy human diets.))
=
((Meat-eating + The availability of non-meat alternatives : Immoral + Unjustified)
+
(Emergency situation + No alternatives available + Meat-eating : Not morally justified, but circumstantially acceptable))
