A nice, but dangerous video

This video looks and sounds as the setting of a fantasy movie, but it’s in reality of video by NASA how Mars would have looked liked four billion years ago. Though this quite amazing from a scientific point of view, I am afraid that it will trigger Mars fanatics to pursue their dream of terraforming Mars. Though terraforming is a common trope in science fiction, it’s little more than that. Scientists know roughly what should be done to terraform a planet like Mars, but we do not know yet any feasible technology to accomplish this.
