The paper presents key stages of the international community’s awareness of the crisis between humanity and biosphere. This understanding became possible due to a number of the UN Conferences on the Environment designed to prevent destructive effects on the planet. The conferences took place during the second half of the twentieth century. The article also considers main provisions of the concept of Universal (Big) History, universal evolutionism, complex systems concept, co-evolution, and holism that might explain new development trends. The author emphasizes evaluation of creating social networks as passing a singularity point with a possible optimistic outcome. Moreover, the study examines some publications on synergetics of education, including schooling, which helped clarify new challenges in forming next generation of the young people. As a result, some “memory traces” were found in the social unconscious. Furthermore, search for fresh approaches to assess community development when the new sociological paradigm with a man in the centre of the scientific model of the world has not fully taken root in social studies is estimated. The work seeks to provide answers to the questions raised while considering novel concepts under current conditions. Several publications with synergistic content are evaluated as well. The paper does not claim to be complete and exhaustive while summarizing the stated issue.
