The environment is the existence world in which human beings depend, and its essence of self-existence is living. Further, the release of the living function forms the environmental productivity which contains three theories about environmental fertility, environment priority and environmentally limited reproduction. With the fertility logic of “give birth to him for myself” and mutual limitation guidelines of “give birth to him and give birth to myself”, environmental productivity stipulates the scope of validity and functional strength of environment itself from two aspects. Given that environmental productivity fundamentally affects the way of human existence, culture direction, the choice of human release and forms the human productivity’s limitation, human’s existence and development can’t exceed the environmental law of limits between self-living and living. Otherwise, earth biotope will be destroyed and climate change will be out of control, which will promote the natural world’s anti-ecological movement and form the the irreversible human ecological crisis, leading to the existence world risks.
