Researchers have found wolves and their prey living inBalance．The wolves keep the deer population fromBecoming too large, and that keeps aBalance in the wilderness plant life．        The real problem is that the areas where wolves can live areBeing usedBy people．Even if wilderness land is not used directly for human needs．The wolves can't always find enough food．So they travel to the nearest source, which is often afarm．Then there is danger．The "bigBad wolf" has arrived!
