The book by Alexey Turchin is an up-to-date review of the latest scientific developments describing how and when the existence of human civilization will end. It talks about all the currently known types of global risks that could destroy humanity, from asteroids to the launch of the Large Hadron Collider and nuclear war. The importance of the book these days is unusually great for two reasons. Firstly, the catastrophe of humanity is an issue that is certainly worthy of our attention. Secondly, the development of many new technologies that can cause global risks is already underway. Understanding how great, real and imminent the risks of the end of the world are, should make you think - how will you personally be saved? This book will require considerable preparation and strength of character, without which an avalanche of technological threats can knock you down. If this happens to you, do not be alarmed and trust the author.
