"Earth became a bustling ecumenopolis rather quickly in the time prior to the year 2500. 99% of its surface is covered in urban sprawl at least a mile deep, with the tallest buildings stretching over ten miles into the sky. There are various skyhooks lining the equator connecting to a number of orbital facilities, and many other large free-floating structures exist in the atmosphere and in orbit."@en .
