The human being came on this earth planet from outside of the planet earth. If we observe in the earth ecosystem, human being is like a guest from outside. The feeling is like that the ecosystem is created for us. But we are not the part of this ecosystem. What are the activities we do is artificial. All activities of this earth ecosystem are natural, except human activity. Human being not adjust with the food cycle clearly.
