The majority of currently tracked space debris is the result of a single anti-satellite missile test China conducted. So less collisions more weapon based destruction. And any future conflict (between nation's reliant upon gps guided weapons)will likely start with anti-satellite warfare. This worries me greatly.

The worst kind of space debris sits in orbits outside of the atmosphere where there is negligible drag. Since these satellites will be in very low orbits that require propulsion to stay aloft, any potential debris from collisions or inoperable satellites will fall back to Earth relatively quickly.

Every satellite floating around without maneuvering capabilities is one more chance for that existing tiny debris to hit something and cause a chain reaction.
