The UN did a population study in the late 1990's which put the maximum sustainable human population at slightly less than 6 billion. We are already well over 7.5 billion, with 9 billion expected by mid century, and possibly 12 billion by the year 2100. With automation, robotics and AI making human labor less necessary every year, it will not be long before half the population is living at or near poverty, while the other half is doing quite well. If pandemics like this CV don't thin out the human "herd", a massive global conflict between the "Haves" and the "Have Nots" will certainly become a real possibility....quite likely before this century is out. If humans don't begin to follow the laws of "supply and demand", the future is not going to be very pretty.
