RE: The U.S. in 2050: Bigger, younger, less white, less urban
Probably, for having an " accurate speculation " we would need to know allot and to create the "accurate speculation " we would need to have a team of many members to analyze every possibility that might happen in the next 40 years.
Indeed there are allot of things worrying most of the people on earth such as : Global Warmth, Environment Destruction, Lack of Energy Resources, Depletion of Drinking Water.
But probably, we might find a solution for each problem and we might even apply each solution for each problem, probably.
