thanks for sharing your explanations and do not give up! The issue is most important for our self (the human family).
There are indeed factors which makes one to be called an elder.
so a plant comes to "existence" out of which reason?
I guess it does not exist out of it self.
Well it can not argue, scream or hurt like other beings but just as I had observed by my self I could not call them mindless. I would not bet on it that there is a second circle of life which is special for plants, but maybe a higher realm
