There would be many different consequences if all the mice in the world died. Mice that live in houses are an inconvenience for people because they chew through walls and sometimes through wiring, and often carry fleas. They also eat cockroaches, so the disappearance of mice would lead to an increase in cockroach infestation. Mice living in the wild (rather than in houses) are eaten by various predators such as owls, ferrets, etc., and those predators would suffer from the loss of this food source, even though they do have other species that they can eat. White mice have been extensively used for laboratory experimentation, and would probably have to be replaced by rats. This is only a partial list of consequences, there would doubtlessly be many more.
