In a hundred years

In a hundred years, there'll be fifteen thousand million people in the world.  Where will they all live?  Our towns will be too small for everyone.  So people will live under the sea, or in the air in enormous balloons.  The "houses" will be smaller than ours.  And they probably won't have any windows, because there'll be nothing to see outside!  Where will everyone work?  There'll be alot of factories, but they'll be full of machines.  What will our food be like?  What will people eat and drink?  We can't be sure.  The world will certainly need a lot more food, and it probably won't taste as good as food today.  Perhaps things will be better in a hundred years.  But we'll never know.  We won't be here.
