Over a period of time your cambelt will wear, the more worn it becomes, the more likely it is to break. If it does break, the car will become undriveable and cause expensive repairs to the vehicles engine to get the car back on the road. On the more positive note, changing the cambelt will increase the fuel efficiency of your vehicle!
A chain-driven engine does not use a timing belt but does require replacement as the chain can stretch overtime causing other problems.
