If it were possible to live without causing harm to any living being at all, then indeed we might well choose not to eat carrots or other vegetables. But that is not possible - merely by being alive, we necessarily cause harm to many, many beings: we step on them inadvertently, we breathe them in without noticing, we kill them when we brush our teeth or wash our bodies, etc.

It takes eight or nine cows a year to feed one average meat eater; each cow eats one acre of green plants, soybeans and corn per year; so it takes eight or nine acres of plants a year to feed one meat eater, compared with only half an acre to feed one vegetarian.
