In 'The Road Science Fiction', the post - apocalyptic world is depicted as a place where nature has been severely damaged. The sky is often overcast, and there's a sense of constant cold and gloom. Food is hard to come by, and most buildings are in ruins. The few survivors are in a constant state of fear and paranoia, which is a clear indication of how harsh the world has become.
It shows a very bleak and desolate post - apocalyptic world. There are no signs of modern civilization functioning well. The landscapes are gray and barren, and resources are extremely scarce. People are desperate and often turn to violence to survive.
