Global Pandemics By Brian Simpson

     The Black Death killed off about one quarter of Europe, and that was before the high urbanisation which we have today, with people living like sardines in a tin, in the modern cesspools called cities.  Today, the probability of a pandemic of some super-disease wiping out civilisation has been rated at 50 percent:

     The last pandemic, the Spanish (actually Chinese) flu killed up to 50 million people worldwide, and society then was not as densely compact as it is today, done for the elites to get mega-bucks from immigration-fuelled population growth.

     We might hope that the modern health and surveillance systems would prevent such a disease outbreak and allow consumer society to chug along on its merry way.  Yet, recent simulations presented to the World Bank have indicated that the systems are not ready for a medium size outbreak, and unprepared for a big or civilisational-threatening one:

     Mass society seemed a good idea at the time, but in the end, as Madison Grant thought, Nordics would need to return to the soil and the land, if they wish to survive for the long-term:
