planet Earth and has one hundred forty-four floors. The top twenty are for recreation and are taken care of by the government to make up for the loss of private land that was sold to private industries by politicians. There are swimming pools, roller- and ice-skating rinks, hiking trails, a zoo, and a bird sanctuary. Forty floors are filled with stores, like traditional malls. Condominiums and cooperative apartments, populated by “Mole Minds,” are on the rest.
