National Trust

The National Trust was a human organisation dedicated to preserving the Earth and everything on it. They owned many natural areas.

After the last humans left the Earth in the Ark, (TV: The Ark) the National Trust set up gravity satellites to hold back the Sun and restored the Earth to its "classic state". In the year 5.5/Apple/26 they ran out of money, so they let the Sun destroy the Earth. (TV: The End of the World)
