According to the study, by the end of this century 25% of the earth’s population, which will hit the 13 billion mark, will reside in urban areas. This will give rise to cities that will be much bigger than anything we’ve seen in human history: cities I like to call mega-mega cities.2019-08-2721 minIT varsity Tech WatchHow cities are becoming smarterIn 2006, for the first time in human history, the number of people living in urban areas equaled the number living in rural areas.

By end April this year, almost 6000 retail stores closed down in the US, while the total number of store closures in 2018 was just 5864.
This a continuation of a trend that has been going on since 2010, and rather than slowing down, it is only showing signs of accelerating. Researchers predict that by 2026, nearly 75000 stores will have closed down in the US alone.
