My friend the astrophysicist would rather disagree. They talk not just about getting in the way of telescopes but also a vast increase in space junk leading to the possibility we run out of safe orbits in which to put things without them getting pulverised by tiny bits of broken satellite.
Space is big. Really big. But apparently space we use for putting things in and travelling through is rather limited and as yet nobody has a way to 'sweep up' so we are reliant on not making it messy to begin with.
