I have often wondered what they did with all those dementors. It was said 
that London and other parts of England had a fog and a chill over it, 
indicating that the Dementors were breeding. If they were breeding, then how 
do you control them? What is the natural enemy of the Dementor, or the force 
that causes their numbers to be reduced? Would the society turning to more 
cheerful thoughts mean they would die off some for lack of "food"? Clearly, 
the fear of Voldemort and the unhappy mood that he was causing was only 
helping the Dementors multiply, but what is the force that causes some of 
them to die off, starve, or have their numbers reduced?

It seems to me that if the Dementors could attack Dudley and attempt to kill 
him (well, to be more accurate, suck out his soul), then a large amount of 
Dementors still in existence would mean a continued threat for all Muggles, 
even after Voldemort had died for good. Wizards would have a way of 
protecting themselves, but the Muggles would be totally helpless. What would 
stop the Dementors from just using Muggles as a new, unlimited food source?
