Is There a Difference Between Above Ground and Underground?

Housing and other things are more likely to be above ground, because people like light. But there are things that can go underground. For example, art galleries can move underground. And if you think of the space that these sort of things are already occupying above ground in major cities. That will basically make available huge space above ground all the shopping centre, et cetera,. If they can move underground then we can have more green spaces above ground instead to fight with climate change and hit island. So above ground, underground, climate issues go hand in hand, i believe.
