Well, definitely, you can’t. Mars is a completely extreme environment to human life, combining extreme cold with unbreathable air and intense radiation.vAnd yet, if we want to expand into the Solar System, we’ll need to learn how to live on other planets. And Mars is prime real estate, compared to a lot of other bodies. So despite it being a challenge, given the right methods and technology, it is possible we could one day live on Mars. Let’s face it, humanity wants to go to Mars, and for several reasons. For one, there’s the spirit of exploration, setting foot in a new world, and exploring a new place. We also need to go there if we want to create a backup location for humanity, in the event that life on Earth becomes untenable due to things like Climate Change. We could also go there to search for additional resources like water, precious metals, or additional croplands in case we can no longer feed ourselves. But there is a problem that Mars is pretty great… if you’re not made of meat and don’t need to breathe oxygen. Otherwise, it’s incredibly hostile. It’s not much more habitable than the cold vacuum of space. First, there’s no air on Mars. So if you were dropped on the surface, the view would be spectacular. Then you’d quickly pass out, and expire a couple of minutes later from a lack of oxygen. I hope that one day we can live in Mar but not now, it possible but we don't know when no one did say we can't, right?
