Abstract: The crisis in environment has given birth to the environmental movement which has gestated the modern non-human centered environmental ethics which is challenging the human centered one. Under the increasing influence of non-human centered ethic theories, the philosophical basis of laws of modern environment should realize its transformation from the human centered view on laws to the ecology centered one. The adjustment should include the one from interpersonal relations to the relations between man and nature. The legal subjects should realize the expanse from persons to non-human existence. And it is the necessity to expand the legal subjects from human to animals, non-human beings, and even nature.
