I'm trying to figure out the name of a certain sci-fi space movie. I can vaguely remember the plot and I've recently (?) watched it too.
The Earth was supposedly ravaged by a war, then turned into a peace haven by some Space Union where no one was allowed to return. Only to be discovered by the main characters that the Earth was actually in fact completely destroyed, the Earth appeared purple-ish in color and had weird alien like features.
But at the end, a small glimmer of life on Earth was found (I remember a small plant) and that's pretty much what I remember.
