Since the early 20th century, scientists and writers have been exploring how/whether Mars might someday become a second home for human beings. The first step is to raise the temperature. When the temperature reaches a higher level, the landscape would change to different scenes. Xiuyu’s animation presents the entire process of terraforming by dividing it into four stages. His understanding of the theory of terraforming and the visual references in the video come from the research I have done with the British Library science collection books about Mars.
