The general public may not want to hear about dystopian futures. Six scientists and investigative journalists gave their perspectives, and then discussed the most impending risks. I watched a rerun on the History Channel (Canada), and note alternative sources.
In the 94 minute show, investigative journalist Michael Ruppert, economist Dr. Nathan Hagens, author John Cronin, investigative journalist/author James Howard Kuntsler, computer scientist Dr. Hugo De Garis, and executive editor Robert Gleason came together to discuss some of the greatest threats to the future of the United States, including economic collapse, water shortages/contamination, peak oil, species dominance by self-aware robots, and nuclear terrorism.
In addition to the summary described in the link above, The Independent Report. emphasizes the impacts of peak oil and debt.
