Yes, low to mid orbits could become difficult to hold. This would present itself as a small statistical likelihood per year for a satellite in these orbits to be struck.

Higher orbits would not be affected, nor would our ability to travel through these regions whatsoever. We would definitely still be able to travel into space just fine. But hanging out in lower orbits for long periods of time would be somewhat dangerous.
