Constructing world sustainability models — The challenge of the future

The authors of this paper analyze the necessity and possibility of constructing and implementing world sustainability model. The starting point of the research is the fact that nature — society — humanity represent unique system elements which are built up on each other. Due to the aforementioned, world management in terms of securing stable and sustainable development is not possible without comprehending self-regulating mechanisms of nature and society. During the research, on the one hand, the authors have made a devastating conclusion: self-regulating mechanisms of nature and society have completely collapsed in contemporary state of affairs. On the other hand, all attempts of constructing world sustainability models have failed, and work on their construction has been suspended. This primarily means that world project management, and thus world management, is impossible. In conclusion, the authors state the reasons which prevent world management form being accomplished and point to the new concept of sustainable development which promises a way out of today's dead-end.
