This Arbor vitae has been growing in this spot for about ten years. Until this year its foliage was lush and green. But now something is very wrong with it as you can see from the photos: cocoon-like structures have infested it.

What is causing this problem? Is it likely to affect other plants? Should I remove this plant?

It looks like bagworms. There are some pictures on this page:

Since it's a small plant you should be able to remove and destroy them to break their life cycle.

@sooby. Thank you so much, Sue!! I think I have removed all of them. The volume was about a quart. They are now in the curbside garbage, which is scheduled to be picked up tomorrow.
