Sculpture of Existence

I have photographed trees for many years, considering the life behind the existence. Some seeds fall to the ground. One gets enough nourishment to sprout and begin to grow. It spends its strength pushing its root into the ground and reaching its branches to the sky to become a tree. Year after year, this continues, the struggle for life, roots into the ground, branches to the sky. Life, diving deeper into the ground and reaching for the sky. The process of building and making over time, life to death. After many years, the tree dies and leaves behind for us the sculpture it spent its existence creating. What is the sculpture of my existence?
