I fail to understand your real meaning. What does it mean 'a tree does not depend on others.....' and then 'mother nature is a bitch'
Every thing is connected with every thing in the world. Mother Nature is the God's manifestation - himself or herself. I am not talking of Quantum Therory, even a primary student can understand that "vriksh kabhi nahi phal bhakhain, nadi na sanchai neer / par karaj ke karne sadhu dharain shareer" (English version : Trees never eat their own fruits, rivers do not collect water for their future security - they do it for others; similarly saintly people live in this world for the welfare of others'
There is a vast Yagya going on in the universe... sun does not shine for itself, air does not flow for itself, water does not exist for itself, earth does not exist for iself and space does not exist for itself.... these all are performing a cosmic Yagya. Sadly, this is a man who does everything for himself and not for others.
Sorry for using 'non-tree' material on this list, but I felt a bit heart at 'mother nature is a bitch'
