Proponents of human colonization of Mars

/in /by

Proponents of human colonization of Mars suggest that a long-term goal would be to terraform the planet’s atmosphere through long-term, large-scale industrial production of greenhouse gasses from

martian
 soil. This is expected to allow liquid water to exist on the surface after a century or two of production. Opponents of the idea feel that this would be too expensive, take too long, and would destroy the natural

martian
 environment. Look up some articles on this topic.
