I think that life in the year 2060 will exist underwater, because the pollution of the air on Earth will be very high. People will build cities with schools, houses and shops to live there.
In my opinion people will travel in special submarines and also they will have submarines buses to take children to school. Clothes for going out from schools and houses will be diving suits. Houses and other buildings will be very simple. I think they will have plants and threes to produce oxygen so we can breath. To make some exercise there will be sport special machines.
I suspect that people will learn to live underwater and finally they will like it.
