Nature does not act with morality in mind. It may be a mistake to look at nature when determining the morality of certain actions. Nature may show us the most effective course of actions, help us find our place in nature, or help us understand why we act the way we do. However, determining what is moral requires introspection because morals are tied to human emotions. Maybe watching Bambi and sympathising with deer is a completely valid reason for not eating venicin simply because our emotions tell us it is wrong. Unfortunately, emotions can also be misguiding and may sometimes interfere with the best course of action, our place in nature, and understanding ourselves.
