There would be many consequences to making the Earth an Ecumenopolis, such as the(almost) complete destruction of the environment. But assuming that we could have a "Green" Ecumenopolis, would you want the Earth to be one, or do you think it would it be wrong to make the only homes for(most of) the other living creatures on Earth ones that we made ourselves?
Ecumenopolis- "World City", think of Coruscant from Star Wars.
