There are ~20,000 objects in orbit large enough to be tracked as hazards. Personally unclear if that includes active satellites, but that’s ‘only’ another ~10,000.
There are ~100,000 airline flights a day worldwide.
How crowded does the sky look with planes?
Yes space junk is a thing to be concerned about / regulate. But at the scales involved it’s basically negligible. We’re orders of magnitude away from any kind of cascade or locking ourselves out of orbit or any other doomsday scenario.
