In the process of the development of civilization, people were able to respond to many of the dangers of natural disasters and social development by changing their lifestyle and new technologies. But today, at the beginning of the new millennium, at the next high turn of the development spiral, it cannot be said that the old traditional types of challenges and threats have completely disappeared. Moreover, new dangers have arisen that have multiplied the risks of accidents, catastrophes and natural disasters so much so that security issues have become a priority for the near future. The next book in the series talks about one hundred of the most significant challenges and threats to our civilization.
