I look upon trees as kind of philosophers and human beings can learn a lot from them and mother nature for that matter! They would rather silently mourn the loss of one of their members!!
If no one is around the tree not only makes no sound but it does not exist at all. A conception absurd to most people but quantum physicists and Prasangikas alike will testify to phenomenon being dependant related. I can't argue my point more clearly as the clarity of my explanation is not requisite of my ability to propound but the readers ability to comprehend. Clear as mud I make myself.
