Question

how is man insignificant compared to nature

Answer 1

"I know not if this earth on which I stand is the core of the universe or if it is but a speck of dust lost in eternity. I know not and I care not. For I know what happiness is possible to me on earth. And my happiness needs no higher aim to vindicate it. My happiness is not the means to any end. It is the end. It is its own goal. It is its own purpose. 

"It is my eyes which see, and the sight of my eyes grants beauty to the earth. It is my ears which hear, and the hearing of my ears gives its song to the world. It is my mind which thinks, and the judgment of my mind is the only searchlight that can find the truth. It is my will which chooses, and the choice of my will is the only edict I must respect.
