The article considers person existence as a main cause of the global problems in the modern civilization development. In this context the person is interpreted as a kind of worldview construction. According to this the human perceives himself as someone equal to the transcendent Absolute. He thinks he can break out of nature bounds. He seems to be an independent creature and opposes himself to his own nature, society, and the world around him. In these conditions, the existence of nature, including the human nature, becomes possible through the prism of human life only. The human gives himself an exclusive right to change and to transform absolutely everything that opposes his life desirers. Thus, human existence becomes the reason of the main problems in the modern civilization development. These problems have got a global character not very long ago. But they form an important part of civilization development in the XXI century.
