Human beings are indeed ontologically rather than ethically or valuably superior to other non-human creatures. In other words, the interests of human beings should not be prior to all the other ethical considerations even though they are the only subjects in terms of ethics and values.

The main point of this article is to seek the spiritual resources suitable for the sustainable development of ecology among Chinese and Western thoughts, such as Confucianism and Christianity, in wishes to build a paradigm of ecologically harmonious society and reach the harmony between human beings and nature.
