United Earth
From Tardis Wiki, the free Doctor Who reference
United Earth was a human government based on Earth.
It was on the front of emerging sometime after the war between the Oceanic States and the Asiatic States reached a stalemate in AD 2071, and will have an Earth presidency. (AUDIO: Casualties of Time)
At some point in the far future, a United Earth spacecraft used the designation "UESC.", and at a time when Earth was being evacuated, a planet was colonised by the United Earth Colonisation Team ship Erehwon. (TV: Smile)
