Answer:
The worst threat of censorship is its ability to erase prominent writers from history.
Explanation:
Book burning represents a form of censorship. It was used to fight political religious and other opponents. In this poem, the author suggests what might be the <u>consequences of these actions</u>.
<em>More disturbing than book ashes are whole libraries that no one got around to writing—desolate towns
</em>
These lines in the poem suggest that book burning deprives libraries of material as well as it prevents writers from writing!
<em>If a book isn’t written, no one needs to burn it
</em>
<em>And there are many I haven’t even written, and nobody has.
</em>
These two lines illustrate possible attitudes of certain writers: their books cannot be burned if they do not write them and this way the poem goes to show the serious consequences censorship could have.
