Throughout Israel there are olive groves that have grown for over 2,000 years. These trees saw Rome come to the area, and eventually fall. They saw much of Biblical history unfold, and they still stand today to bear witness to the trials faced by the region. These trees are highly protected; those who maintain them gather branch trimmings and deadfall and make them available to tourists and woodworkers. At the end of the last ice age, rising water levels caused huge oak forests throughout England, Ireland, and other parts of Europe to die standing and fall into the muck.
