>>We can make all of the Earth rather like the best parts of New York, or Paris or Sydney: picturesque, clean and comfortable. We can then set about to make the rest of the solar system rather like the Earth.

Over half the world's population lives on less than 1% of the land [0]. Only 14% of the land has been modified in any way.
