Depends on what you mean by "Main Problem"
Bella still is the protaganist in Breaking Dawn but Jacob is the second main charachter. I hope this answered your question.
main pressing problem population.
the main setting is were Bella tureds into a vanpire and her babby
Halfway through the book carlile said that the volturie was comeing. And that is the main theme of breaking dawn. ( and her getting pregnent and all!)
Bella gets pregnant and she has to become a vampire because if she doesnt she will die because the baby rips its way out of the mothers stomach
that love is on the inside no matter how someone appears on the outside
Bella and Edward Cullen :D
Edward,Bella,The rest of the Cullens,Jacob,Renesmee
Believe it or not Edward is probably not the second main character. The book Breaking Dawn is split into 3 parts the first is Bella's book, the second is Jacob's book, and the third is Bella's book. So the 2 main characters are Bella and Jacob.
The final book in the main series is titled Breaking Dawn.

Same as usual. Bella, Edward and Jacob. Also introducing Reneesmee
