The fear of pollution

Here’s another snippet you can compress. This one uses a quality (afraid). What would this quality be if turned into a noun?

The idea that we are afraid of pollution is not completely fabricated by priests and princes however.

Rewrite the example using two nominalisations connected by a process.

Again, there are many possible ways to handle this, but here’s the original snippet:

"The fear of pollution is not a complete fabrication of priests and princes, however."
