I am worried about many things. And I think we are already in serious trouble with regards to pollution and climate change. For this one thing, spy satellites in low Earth orbit, I am not so worried. Without active re-boosts, these orbits tend to degrade quickly, and the junk gets dragged out on a relatively quick timescale. Medium orbits, however, can last a super long time, and junk up there is a very serious concern. BTW, as the average global temperature rises, the atmosphere expands, which will degrade the orbits of the lower satellites even quicker!
