To me, natural rights apply to all in nature. I have the right to whatever I can maintain, be it by my own force or innovation, or that of society. A lion has natural rights to the extent that he can procure his own food and can physically survive his environment. A tree has the right to survive assuming it can adapt to its environment. We all have a natural right to survive and act based on our ability to maintain our own life via adaptation, force, or within social constructs.
