Is it morally wrong to live in a house with multiple rooms, or own special clothes just for sleeping? Strictly speaking, we don't need either of those to survive, but we still expend our natural resources because they give us comfort, and so far I haven't heard anybody bitching about the wastefulness of it. Well. My husband bitches about pyjamas being a waste, but not of natural resources. Unless my ass is a natural resource and I don't know about it.
