I'm pretty sure it's just a computer generated Depiction, an actual picture likely wouldn't have the objects visible or would only just barely be visible because they are so small compared to the earth. This one is exaggerated so you can see them.

One of the biggest fears I tend to think of about in space is Kessler Syndrome where one collision creates a shotgun blast of debris that increases the chances for more collisions (cascade effect). If you've seen the movie Gravity you get a great example of how it would go down.

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.

I believe it's just a depiction of it. Looking around some other similar pictures, there were some images where it showed all "space debris" larger than 1cm as like a white dot. So, it's not quite the level of fields of metal floating around out there.
