A Dangerous World informs the reader of the need for disaster preparedness. Topics covered include overpopulation, the economy, environmental pollution and global warming. Other topics include terrorism, Islamic fundamentalism, NBC Warfare and epidemics including the current H1N1 influenza outbreak. Natural disasters including famines, floods, earthquakes, volcanic eruptions and tsunamis are also discussed. The second part of the book informs the reader how to access and interpret his personal vulnerability to disaster situations using the Raven Vulnerability Index. Once assessed, the reader can determine those areas that need improvement and follow the corrective measures outlined in the book. He can also choose his desired preparedness level using the Preparedness Level Scale and outline a long term program to reach that goal.
