Most likely, Bungie will use their "single environment" to constantly provide new locations for the same missions, in order that a player group's impact would be noticable, most likely in a manner to EVE Online, with its many fields of cracked and broken worlds and orbital debris, all caused by player-driven battles. Hopefully, Bungie does something similar.
