What would be if the races of man from Tolkien's works were real?

The races of man from Tolkien's works; the Beornings, Dunlendings, Rohirrim, Beorn's folk, Woodmen, Bree, Gondorians, Haradrim, Easteners, Woses, the Variags of Karna and the Northmen all exist in this world, with the physical and mental traits they have in Tolkien's works. How do you think the modern world would look if all these groups existed?
