Bradbury ends "Fahrenheit 451" with a hope and faith in a better future. The town has been flattened by bombs, but the books of history, faith, fantasy, and all genres live in in the "book people.
"They plan to pass this knowledge onto their children and wait until society needs that knowledge again. They don't have long to wait because several bombs hit the city while they are hiking that day. After weathering the shock waves from the blast, they turn back; civilization needs them. On the way, Montag begins to remember Ecclesiastes."
By ending this novel with the destruction of the city and the world as they knew it, Bradbury is give the idea that changes are coming and this civilization will change and grow, and rebuild like the mythical phoenix to which Granger refers.
"A time to break down, and a time to build up. Yes. A time to keep silence, and a time to speak," Montag thinks as the book people move up the river at the end of the story. "
The book ends as it does because Bradbury has made his point about the emptiness of life without books and the destruction nad repression that can occur when people's primary motivation in life is pleasure and entertainment. He has shown the emptiness of life through the character of Clarisse. All she is interested in is her TV family and has no real relationships. Thus, she turns to suicide and almost succeeds. The irony is crystal clear when all authorities do is send medics to the house because suicide attempts are so common in this empty society, the medics know all about dealing with it. Bradbury has also shown the lengths people will go to protect books. People like the old woman, Carisse, and the forest people all risk their lives to protect the stories and ideas only books can reveal. Once he has shown that a society based on pleasure and the destruction of books is meaningless, he destroys that society and allows for people who cherish books to start rebuilding a new society. That way he can offer hope at the end instead of just a sad warning to society today.
