This book concerns with the relationship between human and nature. We live in a world made by humans, but we cannot forget the natural world, we are part of it, and we dependent on it. Nature gives us a feeling of identification, deep understanding and, finally, a sense of the great community. Awareness of belonging to something much bigger than yourself. 
" I am the Earth And the Earth is me. 
Each blade of grass, 
Each honey tree, 
Each bit of mud, 
And stick and stone Is blood and muscle, 
Skin and bone. "
