Cities will definitely be packed with people, close to 75% of the population; I just wonder what that might look like.   All those folks need energy to power their cities, so maybe, solar ought to work a little harder to get itself up and running, maybe 16% harder.  Heating and cooling will be driving alot of this energy use, close to half needed in Europe.  To keep up with the population, farming must increase at a breakneck pace, over 60% more.  Manufacturing should be taken a look at as well as we must try to catch the best trends quickly in places where manufacturing has left such as England.  The digital landscape is one to be hold too; just ask Australia as they try to figure out how they can better their connected future.  We need the money after all; combating diseases will cost us trillions.
