What is nature?

What is nature?
Is it the greenery that surrounds us?
Does it exclude man-made objects?
Does it breathe, reproduce and eat or not?

What is nature?
Is it the blow of wind?
The roar of flames?
The gushing of water?
The rumbling of earth?

What is nature?
Is it the leaves and grass?
Trees, seas, lakes?
Is it the caves and forests?
Deserts, snow-topped mountains and flowers?

Simply, all of it is.
Even animals and humans
Even the living and non-living
Above and below the hard dirt ground
