A map on what the next ~500 years might look like in the land that is now the United States. I think Greer is little too pessimistic on solar PV (Tom Murphy who actually runs a home PV system seems to think that it's the best future energy source we have for electricity), but I really appreciated the perspectives he offered in this book about scientism (tying of science to social beliefs that are destructive/may not last), the role of technology in the future and the best way to prep (lowering energy requirements, cultivating useful skills).
