How much junk is in space?Why should I worried about space junk?

There´s too much. It is extremely difficult to calculate or observe how much there actually is, but the latest numbers have found more than 20,000 objects larger than ten centimetres  being tracked, and an estimated 500,000 objects larger than one centimetre , not to mention over 100 million objects smaller than one centimetre

 

 

I should worried because for example, a satellite called Uars had reached the end of its useful life and it was left to atmospheric drag to bring it crashing back down to Earth. While UARS can't really be classed as space junk now, there are still over a million pieces of manmade debris still up in orbit.
