Danger from Space Debris

As man had reached to outer space, so do the waste. Now the amount of space debris had reached to a serious level that UN had issued a warning about them causing danger to space flights. Space debris often are created by the remains of rockets, parts of satellites and even defunct satellites. Recently, an Iridium communication satellite had collided with a defunct Russian satellite above Sibera. The Iridium communication satellite was a part of the 66 satellites that are used to provide satellite communication. 
The debris that fall to earth usually get burned out in outer atmosphere itself, but some metals like Ti will not be burned out and can cause damage to earthly objects. In years to come the amount of debris will only increase which will create considerable safety problems to the ISS.
