One thing about the space junk, if we can not leave the planet, will others be able to visit our planet? or even want to after they see all the orbiting junk. Think about it, how many people take a short cut through the messiest back yard on the street?
Perhaps the Aliens have given up on us until we can get our shit together.
Never thought of that way. This is a really nice touch! :D
