To add onto this: I know the movie "Gravity" was just a bit of an exaggeration, but a situation whereby two different satellites are competing for the same spot in the sky and collide or otherwise negatively interact with each other is totally possible. If nothing else, there should probably be some international governance when it comes to orbits, positioning, and mission planning to make sure no one interferes with each other.
