I recently witnessed through my window a healthy tree in the back of my building being taken down. Two workers systematically dismembered the tree using a crane, a buzz saw, and a wood chipper. Within the span of a few hours a decades old vital tree in full bloom was gone. After being stripped of its leaves and branches, its still tall rooted trunk was cut down piece by piece in approximately one foot sections, the saw inexorably slicing through the still living plant. A simple push usually sufficed to slide off the severed section but often that section resisted and the worker had to employ the crane to ram the tree to force the separation. The section fell to the ground as the remaining trunk swayed violently back and forth. Eventually, what was left of the trunk was flush with the ground. A few days later, all visible traces of the tree had been removed.
This was the second tree removed within a few days at the site of what turns out to be a playground renovation.
