"[H. G.] Wells' Utopia is not vegan — nor even vegetarian: the primary motive was to provide human beings with a paradise in which to live. However, there is no reason we should not envisage a vegan version of this Wellsian Utopia, a Garden Earth in which the harms that befall all beings have been eradicated, or at least reduced to a minimum. This might involve eliminating those creatures that are inimical to this project, such as carnivores. Would this be morally acceptable?"
