The picture describes a terrible forest-fire. On the left corner of the picture,there is a fireman in the uniform for his job which is the red jacket with white- striped. He is trying to put off the fire with a water pipe on his hand and we can see the nervous and the precipitation on his face. Being not far from him, the fire is burning onto the air. The water pipes are every where on the grass.It can be said that a part of the forest has an extensive damage and all the firemans are trying to complete their work as soon as possible.
