This book discusses the evolution of civilization and the dangers that emerged in the 20th century: Environmental pollution, depletion of the planet's natural resources, global military conflicts, rapid population growth and the increasing gap in the quality of life in different countries. Factors working to increase these dangers, including the imperfection of human consciousness and the development of increasingly destructive weapons, are analyzed. The book addresses the modern day's most acute problem – the growing multifaceted crisis of civilization – and proposes possible ways to overcome it. It will be useful for a wide circle of readers and can be used as a supplementary source of information by those who study sociology, futurology, psychology, history, conflict resolution and other human sciences.
