Elon has detailed his plan for Mars colonization.

Colonizing and even Terraforming Mars is no longer science fiction. We have the technology to do it now. The real question is should we?

Humans will go to Mars eventually the first people ever to step on a planet that isn't earth are already born!

Exploration is at the heart of humanity. Humans push the boundaries of almost everything, space and colonizing another planet seems like a logical next step, right?

Do we really have the right to disturb another planets ecosystem? Yes Mars is a frozen desert like planet but millions maybe billions of years ago it likely had a much stronger atmosphere and running water and just maybe "life". The planet core cooled (as Mars is less than half the size of earth) and the water evaporated and froze. It can easily be argued that this is just the natural planetary evolution of mars within our solar system in our galaxy in our universe. We don't know what will happen to Mars in the next several billion years as our sun whines down it's own "life". Since we can't know for sure whats to happen perhaps we shouldn't fuck with it and let it evolve on its own?

On the other hand it can be argued that according to our current understanding the sun will swallow us in a few billion years, why not then become a multi planet species and build a second ecosystem to study, learn from and compare to our own? This may just be the building blocks that help humanity outlive our sun!!! It could even be argued that humans colonizing Mars is part of Mars' natural planetary evolution anyways. As soon as humans evolved it was inevitable that the closest inhabitable planet would be colonized eventually.

I personally say GO ELON GO! Get us to Mars and colonize that motherfucker!!! Curiosity, pushing boundaries, exploring and innovation defines our species. Bottling that up won't work so Mars here we come!
