Fe
When a creature dies it becomes cold, but cold steel instead takes on a warmth.
Fe is the chemical symbol for Iron.
The film portrays the indifferent and cold nature of industries, without a care of the ethereal nature of the earth.
Yet nature clings through, attempting to dominate the steel cold iron to reclaim the ethereal beauty of Earth.
The ethereal nature of Earth is not only seen through the beauty of nature but rather in the human relations, our sentiments, because humans are capable of being aware of what is truly beautiful for the ethereal and our connection with other people.
