Space Junk (PBS.org) "There are currently 700 operational satellites in orbit around Earth that are used to monitor the weather, transmit television signals, connect cellphones, assist in GPS for directions among many other critical activities."
"But there are also useless objects such as chips of paint that flaked off space crafts and launch components that helped space shuttles lift off from Earth. Three years ago, an American satellite collided with a Russian satellite over Siberia and created 1,000 more pieces of junk at least 4 inches wide." 03-12
